High-toughness chitosan-based films fabricated by crosslinking via Mannich multicomponent reaction for strawberry preservation.
Chitosan-based films suffer from issues such as poor plasticity and inadequate barrier properties. Herein, high toughness chitosan-based films were fabricated by chemical crosslinking between chitosan with acetoacetylated poly(vinyl alcohol) via the Mannich multicomponent reaction. The structure and properties of the r...
