Biodegradable nanocomposite of poly(ester-co-carbonate) and cellulose nanocrystals for tough tear-resistant disposable bags

Abstract

Current sustainable bioplastics need dramatic improvement to become competitive. Herein, we prepared poly(butylene succinate-co-carbonate) nanocomposites with citric acid and cellulose nanocrystals (CNCs). The dimethyl carbonate co-monomer lowers crystallinity and increases elongation; citric acid increases the strength, and the CNCs maximize mechanical performance. Accelerated biodegradation is also favorable for sustainable tough bags.
