A Fully Bio-Derived Vitrimer from Lignin and Soybean Oil with Integrated Photothermal Conversion, Self-Healing, and Recyclability

To advance the high-value utilization of lignin and develop sustainable materials for clean energy applications, a fully bioderived polyimine vitrimer (VL) was synthesized through an energy-efficient room-temperature process by covalently integrating levulinic acid-modified lignin with a soybean oil-derived diamine....

Chitosan-Based Self-Adaptive Crosslinker-Driven Functional Integration of Polyurethane Foam: High Strength, Intrinsic Flame Retardancy, and Upcycling.

Semi-rigid polyurethane foam plays an indispensable role in the field of safety protection. However, its widespread use has brought challenges of unsustainability and potential fire hazards. Bio-based foams offer a new path to solve these problems, but the complexity of traditional manufacturing processes and their ins...

Lignin-based film with tunable mechanical properties enabled by polyether amine incorporation

To achieve high-value utilization of lignin and develop high bio-based content materials, flexible films were prepared via Schiff base reaction of levulinic acid-esterified lignin with castor oil amine and varying amounts of polyether amine (0 to 50 wt.%). The incorporation of polyether amine as a flexible plasticizing...
