23 Jul Glucose oxidase mediation free radical initiating system and method for preparing hydrogel by using glucose oxidase mediation free radical initiating system
Abstract
The invention relates to a glucose oxidase mediation free radical initiating system and a method for preparing hydrogel by using the glucose oxidase mediation free radical initiating system. The glucose oxidase mediation free radical initiating system consists of a N-hydroxyphthalimide derivative, glucose oxidase and glucose and has the advantages that the initiation condition is gentle, the preparation is simple and convenient, the pH value application range of a reaction medium is relatively wide, and the environment can be protected. According to the method provided by the invention, by adjusting the pH value of the reaction medium or adjusting the concentration ratio of components of a ternary initiating system, monomer polymerization can be initiated within 3-30 minutes at the room temperature under control to prepare hydrogel, and high-strength nano composite hydrogel can be also prepared, so that the method has remarkable application prospect in fields such as controlled-release of medicines, enzyme immobilization, tissue engineering and substance separation.
