| titleOfInvention | A kind of preparation method of catechol-modified chitosan-alginate double network hydrogel |
| abstract | The invention discloses a preparation method of a catechol-modified chitosan-alginate double network hydrogel, comprising the following steps: (1) taking chitosan and a modifier, and reacting to obtain a chitosan derivative The chitosan derivative is catechol graft-modified chitosan; (2) take the chitosan derivative and alginate, add an oxidizing agent, and conduct an oxidative cross-linking reaction to prepare o-phthalic acid. The diphenol-modified chitosan single-network hydrogel; (3) adding a metal salt solution to the catechol-modified chitosan single-network hydrogel for secondary cross-linking and curing, the metal salt solution The metal cation is above divalent, and the catechol-modified chitosan-alginate double network gel is prepared. By adopting a specific cross-linking sequence in the present invention, the prepared double network gel has both good mechanical properties and anti-fatigue properties. |
