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....
