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.

Description

Technical field

[0001] The invention relates to the field of polymer compounds, in particular to a novel glucose oxidase-mediated free radical polymerization initiation system and a method for preparing hydrogels. Background technique

[0002] Polymer compounds play an important role in the field of materials and are widely used in industries, agriculture, biomedicine, environmental protection, and civil life. Common polymer synthesis reactions usually need to control temperature and pressure, which requires high reaction equipment, and sometimes requires the use of toxic catalysts. With the increasing awareness of the sustainable development of human society, the use of high-efficiency, non-toxic, and environmentally friendly synthetic methods to prepare required polymer products is the direction of polymer synthetic chemistry research.

[0003] Biological enzyme is a kind of protein with catalytic function and adjustable activity produced by living cells. It has the following ch...
