Abstract: The chemically cross-linked hydrogel is a hydrogel formed by reaction of silk with a crosslinking agent, and the crosslinking agent is a diglycidyl ether crosslinking agent. The hydrogel is obtained by dissolving silk fibers in a lithium bromide solution and crosslinking through the crosslinking agent. The hydrogel has good elasticity, and can recover more than 90% of its volume/height after being compressed for 100 cycles with a compressive deformation of 20%. The silk is very stable in matrix structure and mechanical properties. After incubation in PBS at 37° C. for 30 days, the content of ?-sheets in the secondary structure elements of the silk is less than or equal to 40%, and its compressive modulus is less than or equal to 100% (with a compressive deformation of 20%). The hydrogel has good biocompatibility and adjustable biodegradability, and can be used for repairing or filling tissues in subjects.
