Extremely strong and tough chitosan films mediated by unique hydrated chitosan crystal structures

Chitosan-based materials have attracted considerable attention owing to their inherent biodegradability, biocompatibility, and antimicrobial properties. However, the establishment of a scalable technology for the fabrication of high-strength and high-toughness chitosan films remains a major challenge. Herein, a new route for the fabrication of high-strength and high-toughness chitosan films mediated by a unique hydrated chitosan crystal...
