Summary: The authors developed a high-performance, degradable, and recyclable bio-based epoxy resin by reacting the lignin derivative vanillin with 4-amino cyclohexanol via Schiff base. This resin exhibited higher Young's modulus and tensile strength compared to bisphenol A epoxy. It also showed good degradation in an acidic environment and recoverability through heat treatment. Additionally, the resin could be used to prepare carbon fiber-reinforced composites, with the carbon fiber being completely recyclable. This study provides a pathway for the preparation of high-performance epoxy resin and the effective recycling of carbon fiber.

Summary: Synthetic materials cause damage over time, so the use of naturally-derived polymers for sustainable material fabrication is gaining recognition. We created hybrid hydrogel sheets using polysaccharides and nanocellulose as wound dressings. Antibacterial properties were added through silver nanoparticles in the polysaccharide blend, and the films were crosslinked via thermal annealing to avoid the use of harmful chemicals. The resulting silver nanoparticle-polysaccharide hydrogels effectively reduce bacterial viability and have potential as on-demand dressings.
