Cellulosic Functional Bioplastic with Tunable Strength and Toughness Through Heat-Treatment of Dynamic Covalent Networks.

ABSTRACT: The growing environmental crisis caused by petroleum-based polymers has intensified the development of sustainable alternatives, with many biomass-derived polymers demonstrating potential for degradability, renewability, and low carbon footprints, though these properties can vary depending on structure and processing. However, traditional bio-based systems often lack tunability in mechanical properties, making it challenging to achieve both high strength and ductility. Herein, we report a high-performance, recyclable bio-based film (CAF-L) constructed via Diels-Alder dynamic covalent chemistry between furfuryl-functionalized cellulose acetate and maleimide-modified lignin. Thermally responsive dynamic Diels-Alder bonds, activated through heat-treatment, enable programmable network crosslin
