| abstract |
The invention discloses a novel high-strength hydrogel which is prepared by the following steps: synthesizing a first network hydrogel from a polyelectrolyte (such as hyaluronate, polyglutamic acid, chondroitin sulfate or polylysine); and after soaking the hydrogel in a double-bond functional polyethyleneglycol water solution for some time, taking out, and crosslinking to obtain the high-strength double-network hydrogel. The synthesized high-strength hydrogel has favorable biocompatibility, can be used as a tissue engineering/repair scaffold material or the like, and has wide applicability in the field of biomedical materials. |
