Internally plasticized poly(vinyl chloride) (PVC) materials are investigated via grafting of propargyl ether cardanol (PEC). The chemical structure of the materials was studied by FT-IR and ¹H NMR. The performace of the obtained internally plasticized PVC materials was also investigated with TGA, DSC and leaching tests. The results showed that grafting of propargyl ether cardanol (PEC) on PVC increased the free volume and distance of PVC chains, which efficiently decreased the glass transition temperature (T_g). No migration was found in the leaching tests for internally plasticized PVC films compared with plasticized PVC materials with commercial plasticizer dioctyl phthalate (DOP). The internal plasticization mechanism was also disscussed according to lubrication theory and free volume theory. This work provides a meaningful strategy for designing no-migration PVC materials by introducing cardanol groups as branched chains.

A facile and environmental-friendly approach was developed for the preparation of the cross-linked nanocellulose aerogel through the freeze-drying process and subsequent esterification. The as-prepared aerogel had a three-dimensional cellular microstructure with ultra-low density of 6.05 mg·cm⁻³ and high porosity (99.61%). After modifying by chemical vapor deposition (CVD) with hexadecyltrimethoxysilane (HTMS), the nanocellulose aerogel displayed stable super-hydrophobicity and super-oleophilicity with water contact angle of 151°, and had excellent adsorption performance for various oil and organic solvents with the adsorption capacity of 77~226 g/g. Even after 30 cycles, the adsorption capacity of the nanocellulose aerogel for chloroform was as high as 170 g/g, indicating its outstanding reusability. Therefore, the superhydrophobic cross-linked nanocellulose aerogel is a promising oil adsorbent for wastewater treatment.

Ionogels have emerged as a groundbreaking category of materials for flexible electronics, yet the challenge of integrating high mechanical stretchability, rapid electrical response, and reliable self‐repair in bio‐based ionogels persists. Here, a lignin‐derived ionogel is presented, designated P(LA‐TA)‐gel, through a straightforward, one‐step solvent‐free process. By leveraging arginine‐grafted lignin‐terminated polythioctic acid and incorporating imine and hydroxyl groups into the supramolecular framework, the P(LA‐TA)‐gel with both dynamic disulfide bonds and supramolecular hydrogen bonds achieves effective energy dissipation channels. This configuration adeptly balances mechanical stretchability—exhibiting a strain of 1233%—with dynamic reversibility, evidenced by an adhesion strength of 335.5 kPa. Notably, the P(LA‐TA)‐gel showcases rapid response characteristics, achieving a response time of 0.1 s, along with high ionic conductivity of 17.36 mS cm ⁻¹ and robust self‐healing capabilities exceeding 90%. When utilized in flexible sensors, this ionogel demonstrates a wide response range and high sensitivity. This study establishes a sustainable platform for the development of next‐generation flexible sensors and highlights significant potential applications across wearable electronics, electronic skin technology, and soft robotics.

An epoxy resin adhesive based on β-hydroxyester bonds and multiple hydrogen bonds was prepared with tung oil and lignin. Molecular dynamics simulation was used to regulate the structure and properties of adhesives.
