Fracture toughness, a parameter representing the resistance to fracture and capacity of a material to absorb impact force or energy, is one of the key performance indicators that need to be considered when selecting plastics to fabricate the parts for critical structural applications. Most plastics exhibit brittle type of fracture with low fracture toughness which can greatly limit their performance especially for long-term and special applications. A relatively simple and straightforward strategy to enhance the fracture toughness is incorporating elastomers into plastics via direct melt compounding processing. However, in the case of polypropylene composites, the existence of a second phase including filler or fiber and the importance of interfacial bonding between the polymer matrix and filler, requires the mechanism and the effectiveness of toughening strategy to be studied carefully. This paper presents an overview of the toughening mechanism in Polypropylene and provides the details of different techniques for achieving the right balance between strength and toughness in thermoplastic composites. The concept of toughness in this work covers both macro and micro-level toughness that refers to structural toughness and toughness as impact behavior of composites. The factors influencing the efficiency of toughened polymer composites are discussed in detail. Current challenges and future direction in toughening mechanism in thermoplastics composites are proposed for promoting the application of different strategy or combining a couple of strategies for enhancing the fracture toughness of thermoplastic composites.

The COVID-19 pandemic is the largest global public health outbreak in the 21st century so far. Based on World Health Organization reports, the main source of SARS-CoV-2 infection is transmission of droplets released when an infected person coughs, sneezes, or exhales. Viral particles can remain in the air and on the surfaces for a long time. These droplets are too heavy to float in air and rapidly fall down onto the surfaces. To minimize the risk of the infection, entire surrounding environment should be disinfected or neutralized regularly. Development of the antiviral coating for the surface of objects that are frequently used by the public could be a practical route to prevent the spread of the viral particles and inactivation of the transmission of the viruses. In this short review, the design of the antiviral coating to combat the spread of different viruses has been discussed and the technological attempts for minimizing the coronavirus outbreak have been highlighted.

In this study, a novel scalable method based on hydrothermal-assisted ball milling was used to simultaneously synthesize and amino-functionalize molybdenum disulfide nanosheets with diaminodiphenyl sulfone (DDS-MoS2). This process resulted in the production of the functionalized nanosheets with a lateral dimension of ~600–900 nm and thickness of ~2–6 nm without requiring a lithium intercalation step. The inverse gas chromatography results revealed that total surface energies of the nanosheets significantly increased after DDS functionalization, making them highly compatible with epoxy resin. Epoxy nanocomposites containing 0.5 wt% of DDS-MoS2 nanosheets showed ~30% and ~28% increases in tensile and flexural strengths, respectively. Additionally, ~16% and ~12% enhancements in tensile and flexural modulus, respectively, were observed in these nanocomposites. The inclusion of DDS-MoS2/epoxy resin in carbon fibre composites led to the fabrication of multiscale nanocomposites with improved mechanical properties. In these multiscale nanocomposites, flexural modulus and strength were considerably improved by ~33.7% and ~29.5%, respectively. Compared to other two-dimensional nanomaterials, such as nanoclay and graphene derivatives, DDS-MoS2 nanosheets showed promising behaviour for both epoxy nanocomposites and multiscale carbon fibre nanocomposites. These achievements could be associated with the synergistic effect of DDS-MoS2 in both promoting the interfacial stress transfer and the energy dissipation through different crack retardation mechanisms.

Lithium (Li) metal is widely accepted as the most promising anode for next-generation batteries due to its highest theoretical capacity (3,860 mA h g−1) and lowest electrochemical potential (−3.04 V versus standard hydrogen electrode). However, Li-metal anodes suffer from low Coulombic efficiency and safety issues, due to the high activity and uncontrollable Li dendrite growth. Here, we demonstrate that a novel two-stage “outside-in” Li deposition behavior achieved through the use of bio-derived hollow carbon fiber textile with unique hierarchical porosity. We show that Li deposition first occurs on the external surface because of the abundant lithiophilic pores, followed by deposition both inside and on the wall of the hollow carbon fiber. This pore-induced mechanism is crucial for the carbon fiber textile serving as a stable and robust host for uniform Li deposition. This Li composite anode exhibits a high Coulombic efficiency for more than 500 cycles and high cycling stability of over 1,400 h at a current density of 1 mA cm−2. The scalable production and the novel understanding on the function of hierarchical porous structure provide critical insights into design and synthesis of carbon-based materials as hosts for Li anodes.

The significant rise in contamination of wastewater, water and ground water or sediments with PPCPs is a clear evidence that nowadays applied treatment methods are inefficient in removal of these contaminants. In this study a novel cotton based adsorbent is used for efficient sorption of naproxen (NAP), caffeine (CAF) and triclosan (TCS). The adsorption of tested contaminants differed significantly: the highest amount of PPCPs sorbed was noted for TCS sorption onto CMT9 137 mg g−1, whereas the lowest adsorbed amount, 19.73 mg g−1, was observed for NAP sorption onto CMT13. The presence of co-solute affected both the mechanism of sorption and the amount of PPCPs sorbed: in the presence of TCS the sorption of NAP was changed from chemical to physical. Similarly, in the presence of TCS the mechanism of NAP sorption onto CMT13 changed from chemisorption to diffusion inside the pores. The presence of CAF definitely increased NAP sorption and partitioning. The presence of TCS increased CAF sorption, whereas the presence of NAP in the solution increased CAF sorption only onto CMT11. The NAP sorption in the presence of CAF was significantly enhanced and data confirmed that diffusion through the pores is the most often observed mechanism of selected PPCPs sorption onto CMTs. It is believed that the synthesized cotton-based adsorbents offer a unique opportunity for the sustainable PPCP removal from wastewater.

The effect of UVA-Vis irradiation of magnetic microtubes derived from cotton waste on the process of Bisphenol A (BPA) removal and mineralisation is studied. The magnetic microtubes were developed by ultra-fast microwave treatment of carbonised cotton waste to grow Fe3O4 nanoparticles onto the surface of tubes. The activity of magnetic microtubes was tested in the removal of BPA, both in the dark adsorption and under UVA-Vis irradiation. The highest dark adsorption capacity was measured for sample carbonized at 1100 °C (208 mg·g-1), confirming its high potential in BPA removal from water through direct adsorption. The highest changes in water pollution were observed during the first 10 min of treatment. Toxicity of BPA was significantly reduced after treatment and applied procedures enabled the high quality non-toxic water. The obtained results clearly indicate that the ultrafast and solvent free magnetisation of carbon microtube derived from textile waste offers a low-cost solution for the efficient photo mineralisation of BPA.

Balancing the performance, durability and safety requirements of automotive systems with the regulatory landscape in an environment of climate change has accelerated the search for sustainable fiber reinforced polymer composites for automobile structures. Glass fiber reinforced thermoplastic polymer composites (GFRP) are widely used in certain structures like front end modules and liftgate; However, they cannot be used in more demanding applications due to their low mechanical properties. Carbon fiber reinforced thermoplastic polymer composites (CFRP) are promising candidates for applications like bonnet, but their use is constrained by cost. Basalt fiber reinforced thermoplastic polymer composites (BFRP) are sustainable materials that can be positioned between GFRP and CFRP in terms of performance and cost-effectiveness. The mechanical performance of the BFRP depend on the quality of the fiber-matrix interface that aids in efficient load transfer from the matrix to the fiber. Typically, basalt fibers are inert in nature and need treatments to improve its adhesion to polymeric matrices. The major chemical treatments that are reviewed in this article include matrix functionalization, silane treatment, functionalized nanomaterial coating and plasma polymerization. The physical treatments reviewed include plasma treatment and milling. It is evident that chemically treating the basalt fiber with a functionalized nanomaterial yields BFRP with a good stiffness – toughness balance that can be used for challenging metal replacements as also in new emerging areas like sensing and 3D printing.

In a circular economy model the way we use the textiles needs to change at a fundamental level. A circular economy is an alternative to a traditional economy (fabrication, use and dispose) in which we keep resources in a loop for as much time as possible, try to maintain their value while in use, and repurpose for generation of new products at the end of utilization. The value of the global fashion industry is 3000 Billion dollars that accounts for more than 2% of the world's Gross Domestic Product (GDP) (https://fashionunited.com/global-fashion-industry-statistics/). In the last two decades not only the textile industry has doubled the production but also an average global annual consumption of textiles has doubled from 7 to 13 kg per person and reached to the threshold of 100 million tonnes of textiles consumption. More than two thirds of the textile goes to landfill at the end of their use and just around 15% is recycled. Various scientific studies confirm that the disposal nature of fast fashion and throwaway culture is resulting in a serious environmental, health, social and economic concern. One of the global environmental challenges arising from micro-plastic and micro-textile waste entering into the oceans that can end up in fish and eventually food chain. Herein, through a systematic literature review, the significance of circular fashion and textile is highlighted and various approaches for reuse, recycle and repurposing of the textiles waste as well as disruptive scientific breakthroughs, innovations and strategies towards a circular textile economy have been discussed. Looking into the future, remarks have been made in regards to tackling the key challenges in recycling of textile materials in different stages of their manufacturing process.

For practical applications, both environmental and economic aspects are highly required to consider in the development of recycling of fibre reinforced polymers (FRPs) encountering their end-of-life. Here, a sustainable, low cost, and efficient approach for the recycling of the glass fibre (GF) from GF reinforced epoxy polymer (GFRP) waste is introduced, based on a microwave-assisted chemical oxidation method. It was found that in a one-step process using microwave irradiation, a mixture of hydrogen peroxide (H2O2) as a green oxidiser and tartaric acid (TA) as a natural organic acid could be used to decompose the epoxy matrix of a waste GFRP up to 90% yield. The recycled GFs with ~92.7% tensile strength, ~99.0% Young’s modulus, and ~96.2% strain-to-failure retentions were obtained when compared to virgin GFs (VGFs). This short microwave irradiation time using these green and sustainable recycling solvents makes this a significantly low energy consumption approach for the recycling of end-of-life GFRPs.

In this study, we have developed a rapid, cost-effective, environmentally green, and yet efficient approach for the complete reclamation of the carbon fibre composites through a microwave assisted chemical method. It was found that in a catalyst-free and one-step process using microwave irradiation, a mixture of hydrogen peroxide (H2O2) and tartaric acid (TA) can initiate decomposition of the epoxy matrix up to 95% yield, leaving behind CFs with ~92% tensile strength and ~94% strain-to-failure retentions compared to the original CFs. Less than 2 min microwave irradiation was used which makes this approach considerably promising for the fast reclamation of the carbon fibre composites. The repetition of reclamation for the second and third times, which have been performed on the composite laminates re-manufactured using the reclaimed CFs, indicated that further reductions in the CFs mechanical performance are typically less than 5% after first reclamation process. Our proposed reclamation process changed surface properties of the reclaimed CFs compared to original CFs, which led to a significant increase in interfacial performance of the recycled CFs-epoxy composites. Moreover, the re-manufactured composite laminates using the reclaimed CFs showed highly comparable flexural strength and modulus, compared to its original composite laminates.

Mollusk shells, a natural bio composite with a hierarchical layered microarchitecture composed of mineral tablets and interleaved with organic biomaterials matrix has emerged as a promising alternative for the development of advanced functional and high-strength materials. It is widely acknowledged that the nature-mediated complex hierarchical intricacies in such design architecture are dimensionally a great challenge to imitate in artificial materials. However, the macroscopic illustration of architectonic principle possesses ability to render improved mechanical property in commercially available polymeric systems. In this context, the current study elucidates the macroscopic dimensional imitation of various mollusk architecture in polycarbonate via 3D printing by utilizing fused deposition modelling without utilizing interleaved biopolymer. The resulted architectures were subsequently compared for their impact, wear, and tensile characteristics and demonstrated that the exploration of complex laminar design strategy in polycarbonate elucidated ~48% augmentation in mechanical property compare to other hierarchical architecture like nacre, foliated, and complex cross laminar structure. It is envisioned that such design strategies in engineering polymers possess ability to open new avenue for further improving mechanical properties without altering their intrinsic characteristics.

Present study reports superhydrophobic-oleophilic, environment-friendly, & biodegradable silk material derived from Bombyx mori silkworm, for practical oil-water separation and oil recovery applications. In this study, raw silk fibers were degummed using water and Na2CO3 (at 100 °C), for removal of outer gummy sericin protein layer, which was confirmed using FTIR & FE-SEM analysis. The water & Na2CO3 degummed silk fibers showed superhydrophobicity with water contact angles (WCA) of 153° & 158°, respectively, demonstrating Wenzel & Cassi-Baxter states. Degummed silk fibers showed superoleophilicity (OCA∼0°) towards petroleum oils like Petrol, Diesel, & Engine oil. The water & Na2CO3 degummed silk fibers showed oil-water separation efficiencies of 95 % & 87.5 %, respectively. Both degummed silk fibers showed more than 50 % efficiency till 10 separation cycles. Further, raw & degummed silk fibers showed an environmental biocompatibility, by their biodegradation under in-house developed biotic de-compost culture consisting of biodegrading micro-organisms. Their analysis showed that biotic de-compost culture rendered biodegradation weight loss of 11 % and 18 %, respectively, in 35 days. Successive results showed that, degummed silk fibers can be effectively utilized for practical oil-water separation, and further, they can be environmentally biodegraded, thereby mitigating their waste generation and disposal problem.

Graphene based flame retardants have gained increasing attention among researchers due to some interesting properties such as the tortuous path effect. Nonetheless, their complex, unsustainable, eco-unfriendly, and costly production hinder their adoption in various fields. Here, we used waste deoxyribonucleic acid, generated by the fishing industry, as a sustainable source of phosphorus and nitrogen to functionalize graphene nanomaterials. Our scalable and one-step approach, which employs waste-derived deoxyribonucleic acid as a green modifier in the ball milling process, is capable of producing the deoxyribonucleic acid-functionalized graphene nanoplatelets from graphite with high production yield, high oxygen, nitrogen and phosphorus contents, and high water dispersion concentration. Such a synthesized approach led to the exfoliated nanoplatelets, mostly consisting of layers with a thickness <9 nm and a lateral size of 300–600 nm, with the Brunauer–Emmett–Teller specific surface area of ∼180 m2/g. The remarkable effect of the deoxyribonucleic acid-functionalized graphene as an efficient and sustainable flame retardant on fire extinguishing of a wide range of polymer matrices including epoxy resin, polyvinyl alcohol, and polystyrene nanocomposites was successfully evidenced by achieving V-0 rating in UL-94 vertical burning tests. A multilayer char residue consisting of a compact layer and a porous layer was found to be the dominated mechanism in the fire extinguishing. The combination of deoxyribonucleic acid and graphene can result in manufacturing value-added green flame retardants from indirect reuse of fish waste, which can be suitable for high performance polymer nanocomposites including construction, automotive and aerospace. It is envisaged that the loop from fish waste to green flame retardants may come to be closed soon, which can be the main goal of the circular economy in cutting-edge applications.

Synthesis of two dimensional (2D) nanomaterials from natural resources for the fabrication of high performance multifunctional polymer nanocomposites has gained great interest. Herein, we report on a facile method for synthesizing 2D bauxite nanosheets (BNS) directly from its ore using a combination of ball-milling and hydrothermal processes. Successful preparation of the BNS was confirmed using scanning electron microscopy (SEM), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) specific surface area, and particle size distribution. The changes in phases monitored by X-ray diffraction (XRD), before and after ball-milling and hydrothermal treatment, indicated the presence of γ-Al2O3 in the BNS structure. As a promising application, the BNS was introduced into a thermosetting epoxy resin. Thermal analysis and rheological analyses were performed to understand the influence of BNS on the curing and processing of the epoxy matrix. Higher mechanical performance of the epoxy resin reinforced with BNS was achieved and characterized using tensile, flexural, and dynamic thermo-mechanical (DMT) analyses. Thermal stability of the epoxy nanocomposites containing BNS were also evaluated using thermogravimetry analyses (TGA). The overall results indicate that BNS can effectively serve as a cost-effective multifunctional reinforcing agent in fabrication of high performance epoxy nanocomposites.

The most known analogue of graphene, molybdenum disulfide (MoS2) nanosheet, has recently captured great interest because it can present properties beyond graphene in several high technological applications. Nonetheless, the lack of a feasible, sustainable, and scalable approach, in which synthesizing and functionalization of 2H-MoS2 nanosheets occur simultaneously, is still a challenge. Herein, a hydrothermal treatment has been utilised to reduce the effect of breaking mechanisms on the lateral size of produced nanosheets during the ball milling process. It was demonstrated that the hydrothermal pre-treatment led to the initial intercalation of an organic molecule such as 4,4’-diaminodiphenyl sulfone (DDS) within the stacked MoS2 sheets. Such a phenomenon can promote the horizontal shear forces and cause sliding and peeling mechanisms to be the dominated ones during low energy ball milling. Such combined methods can result in the production of 2H functionalized MoS2 nanosheets. The resultant few layers showed an average lateral dimension of more than 640 nm with the thickness as low as 6 nm and a surface area as high as 121.8 m2/g. These features of the synthesised MoS2 nanosheets, alongside their functional groups, can result in fully harnessing the reinforcing potential of MoS2 nanosheets for improvement of mechanical properties in different types of polymeric matrices.

Carbon fibre composites offer considerable potential for mass reduction in automotive applications. However, raw material cost is one of the major factors that constraints its extensive use in this mass market. Here we report a systematic study that presents the cost contributors by considering the entire process chain of the carbon fibre manufacturing. The sensitivity analysis revealed that the final cost of Polyacrylonitrile (PAN) precursor and carbon fibres were strongly influenced by tow size. It was observed that a prompt decrease in the precursor and carbon fibre cost per kg for tow sizes from 3k to 12k, later this decrement was gradual and almost became stable above 50k. Moreover, with an increase in tow size from 3k to 50k, the contribution of the precursor on the final carbon fibre cost decreased from 76.6% to 49.6%. On the other hand, the contribution of the other factors increased with increase in the tow size, for instance, labour (9.86%–17.78%), Energy (2.49%–6.48%) and Depreciation (6.11%–11.01%). Nevertheless, precursor holds the major share in determining the final price of the carbon fibres.

For most carbon‐based materials, hierarchical porous structure including well‐defined macropores, mesopores, and micropores is commonly seen in 3D aerogels, monoliths, or some carbothermic natural biomass. However, because of the filiform character and long draw ratio, it is difficult to achieve such pore network as well as attain excellent mechanical performance in a 1D single carbon fiber system. To address this issue, an innovative hierarchical porous and hollow carbon textile (HPHCT) is developed via the “dynamic template (KOH, SiO2, and Al2O3) calcination” strategy. Unlike conventional one‐step activated carbonized fiber simply with meso or micropores, the fabricated textile generates honeycomb‐like macropores uniformly spreading on fiber surface. More importantly, the ultra‐lightweight yet flexible HPHCT is mechanically robust, superior to ordinary carbonized one. In addition, it delivers high capacitance of maximum 220 F g−1 as well as keeping long term stability with 100% retention after 10 000 cycles as freestanding electrodes in supercapacitor. Meanwhile, the all‐solid integrated symmetric HPHCT supercapacitors demonstrates its high potential in powering electronics for wearable energy storage application.

Polyacrylonitrile (PAN) is a versatile man-made polymer and has been used in a large array of products since its first mass production in the mid 40s. Among all applications of PAN the widely used application is in manufacture of precursor fiber for fabrication of carbon fibers. The process of PAN-based carbon fiber production comprises fiber spinning, thermal stabilization and carbonization stages. Carbon fiber properties are significantly dependent on the quality of PAN precursor fiber and in particular the process parameters involved in thermal stabilization. This paper is the first comprehensive review that provides a general understanding of the links between PAN fiber structure, properties, and its stabilization process along with the use of mathematical modelling as a powerful tool in prediction and optimization of the processes involved. Since the promise of the mathematical modelling is to predict the future behaviour of the system and the value of the variables for the unseen or unmeasured domain of variables; and in the era of industry 4.0 rise, this review will be valuable in further understanding of the intricate processes of carbon fiber manufacture and utilising the advanced mathematical modelling using machine learning techniques to predict and optimize a range of critical factors that control the quality of PAN and resultant carbon fibers.
