Abstract

High-flexibility, high-toughness double-cross-linked (DC) chitin hydrogels are prepared through a sequential chemical and physical cross-linkings strategy. The incorporation of chemically and physically cross-linked domains imbues the DC chitin hydrogels with relatively high stiffness, high toughness, and toughness recoverability.
