Strong, ductile and biodegradable polylactic acid/lignin-containing cellulose nanofibril composites with improved thermal and barrier properties

Currently, it is challenging to produce biodegradable polylactic acid (PLA) composite with both high strength and great ductility. In this work, lignin-containing cellulose nanofibrils (LCNF) derived from old newspaper were amalgamated with a biodegradable PLA matrix to prepare multifunctional composites with integrated strength and ductility. Owing to the lignin content of LCNF, the interfacial interaction and compatibility between LCNF and PLA...
