Ayesha KausarPolyurethane foam is a polymeric material having cellular structure. Multifunctional polyurethane foams reinforced with nanofiller have combined enhanced specific properties with density reduction. This article primarily considers important aspects of various foam processing techniques. Numerous nanofillers such as graphite, graphene, graphene oxide, carbon black, carbon nanotube, nanoclay, and inorganic nanoparticle have been reinforced in polyurethane foam. Particular attention is given to various categories of polymer/carbon nanofiller and polymer/inorganic nanofiller composite foams. Applications of polyurethane composite foams have been focused with relevance to aerospace and automotive industry, radar absorbing and electromagnetic interference shielding, oil absorbants, sensors, fire proof, shape memory, and biomedical materials.

Currently, a lot of research efforts have been directed toward exploiting the special high-performance characteristics of polymers with sulfur in the backbone. Sulfur-containing polymers fall under various classes and cover an extremely broad property range. The impetus to their development resulted from the unique properties and success in their applications, depending upon the type of linkage introduced. This review basically sets out to explain the design, synthesis, properties, and applications of various sulfur-containing polymers especially polyamides, polyimides, poly(amide-imide)s, polybenzimidazoles, polyurethanes, polyesters, etc. Outstanding performance of these polymers came up from their structures having sulfur-based groups such as thiophene, sulfide, sulfone, thiazol, and thiourea. Thus these linkages endow special features to such functional polymers. The sulfur-containing polymers are also described here with reference to their relevance as optically active, liquid crystalline, flame retardant, and fuel cell materials. Several endeavors are underway to take advantage of incorporated sulfur moiety in the polymer backbone, as a consequence to ascertain their validity on the forefront of scientific investigations.

In this review, potential and properties of carbon nanotube, graphite, graphene oxide, and clay nanofiller have been deliberated with reference to aerospace application. The polymers discussed as matrices are polypropylene, polyaniline, polyurethane, polystyrene, and polyamide. Main focus of the review is to converse space competency of polymer/carbon nanotube, polymer/graphite, polymer/graphene oxide, and polymer/clay nanocomposite. The effect of nanofiller addition on the desired aerospace properties of polymeric nanocomposite has been conversed. Attractive features are high glass transition temperature, thermal stability, high modulus, chemical resistance, and nonflammability. Toward the end, challenges in the enhancement of materials’ properties for aerospace relevance have been considered.

Ayesha KausarThis is an overview of polymer coating technology, which is a way for altering surface properties to meet performance requirement in variety of technical applications. Polymer coatings have been utilized for purposes of adhesion, barrier properties, scratch and abrasion resistance, chemical resistance, wettability, biocompatibility, etc. Different approaches have been developed and adopted for fabrication of protective organic coatings. A judicious choice of polymer, coating technique, and fabrication parameters may lead to high performance coatings with upgraded properties. Recently, polymer coatings have been successfully and frequently adopted for solar cell, lithium-sulfur batteries, membrane technology, Light-Emitting Diode, corrosion protection, packaging, and biomedical.

Ayesha KausarPolycarbonate is an important thermoplastic polymer. Due to its high performance, polycarbonate has a range of engineering applications in construction, automotive, aircraft, data storage, electrical, and telecommunication hardware. However, polycarbonate’s use is limited in advanced applications due to limitations, such as strong hydrophobicity, relatively limited chemical functionality, high melt viscosity, notch sensitivity of mechanical properties, and relative softness. Blending with other thermoplastic polymers improves its physical characteristics. The present review outlines up-to-date developments concerning the design and application of polycarbonate blends. A particular emphasis has been given to establish polycarbonate blends such as: • polycarbonate/polyethylene • polycarbonate/poly(methyl methacrylate) • polycarbonate/poly(vinylchloride) • polycarbonate/ polystyrene • polycarbonate/polyurethane • polycarbonate/polyester • polycarbonate/poly(ɛ-caprolactone). To improve the polycarbonate blend properties, fillers including organic and inorganic reinforcement materials (carbon nanotube, montmorillonite nanoclay, and metal nanoparticle) have also been employed. Polycarbonate blend applications in biomedical, flame retardant, and membrane materials have also been reviewed. To fully exploit the future potential for polycarbonate-based engineering materials, the structure–property relationship and compatibilization mechanisms need to be further explored.
