NOVELTY - Cross-linking eco-friendly hydrogel involves preparing graphene oxide, adding in deionized water, and ultrasonically dispersing to obtain solution A, dissolving sodium chloride, potassium chloride, disodium hydrogen phosphate, and dipotassium hydrogen phosphate in deionized water, adjusting the pH value of solution with hydrochloric acid, and preparing solution B, weighing sodium alginate powder and chitosan powder and mixing thoroughly to obtain mixed powder a, adding to the solution B, then adding solution A, heating and stirring the whole system to obtain solution C, injecting into the container to make uniformly covers the surface of container, weighing calcium carbonate powder, calcium sulfate powder, calcium chloride powder and fully mixing to obtain mixed powder b, adding the mixed powder b into deionized water to obtain solution D, immersing the container covering solution C into solution D, then taking it out, letting it stand for cross-linking, and obtaining the product. USE - Method used for cross-linking eco-friendly hydrogel containing graphene oxide in field of medical cosmetology or in dressings (claimed). ADVANTAGE - The method utilizes good protein adsorption function and mechanical enhancement function of the three-component cross-linking agent and graphene, solves the technical defects of alginate hydrogel cross-linked by one-component and two-component cross-linking agent, significantly accelerates the cross-linking speed of alginate hydrogel and improves its cross-linking degree, and improves cross-linking speed, mechanical properties and anti-cracking properties of the hydrogel.
