Abstract: A method for preparing a chemiluminescent hydrogel is disclosed, belonging to the field of luminescent materials. The method for preparing a chemiluminescent hydrogel includes the steps of: slowly adding chitosan to an acetic acid solution, stirring at room temperature until completely dissolved, adding a cobalt chloride solution, followed by a polyvinyl alcohol (PVA) solution, sufficiently stirring, ultrasonically defoaming, and subjecting a resulting mixture to an alkaline bath treatment with an alkaline solution, adding N-(4-aminobutyl)-N-ethylisoluminol (ABEI), and stirring with a hydrogen peroxide solution to obtain the chemiluminescent hydrogel. The synthesized hydrogel has the advantages of high luminous intensity and long duration. In the process, a high-water-cut polymer with a three-dimensional network structure obtained by chemical crosslinking with the addition of PVA features excellent biocompatibility, high elasticity, and nontoxicity, and is one of biomedical materials with application potential.
