Title:
METHOD FOR PREPARING CHEMILUMINESCENT HYDROGEL
Document Type and Number:
WIPO Patent Application WO/2022/032714
Kind Code:
A1
Abstract:
A method for preparing a chemiluminescent hydrogel, belonging to the field of luminescent materials. The method for preparing a luminescent hydrogel comprises: slowly adding chitosan to an acetic acid solution, stirring same at room temperature until the chitosan is completely dissolved, then adding a cobalt chloride solution, followed by a polyvinyl alcohol solution, sufficiently stirring same, then ultrasonically defoaming same, and subjecting same to an alkaline bath treatment with an alkaline solution and adding N-(4-aminobutyl)-N-ethylisoluminol (ABEI), stirring same, and then adding a hydrogen peroxide solution to obtain chemiluminescent hydrogel. The synthesized hydrogel has the advantages of high luminous intensity, being long-lasting, etc. In the process, a high-water-content polymer with a three-dimensional network structure obtained by means of chemical crosslinking with the addition of polyvinyl alcohol has the characteristics of good biocompatibility, high elasticity, being non-toxic, etc., and is also one of biomedical materials with application potential.
