23 Jul Gelatin hydrogel and preparation method and application thereof
Abstract
The invention discloses gelatin hydrogel, which is of a water molecule filled porous three-network structure, wherein the first network is a cross-linked network between the modified gelatin; the second network is a cross-linked network between polyethylene glycol diacrylate; the third network is a cross-linked network between the modified gelatin and the polyethylene glycol diacrylate. The invention also discloses a preparation method of the gelatin hydrogel. By using an ultraviolet light catalytic crosslinking technology, the modified gelatin is cross-linked with the polyethylene glycol diacrylate; the gelatin hydrogel is obtained through preparation. The gelatin hydrogel provided by the invention has the advantages that the elasticity modulus and the degrading performance of the support frame can be regulated and controlled through changing the modification degree of the modified gelatin and the addition quantity of the polyethylene glycol diacrylate; the structure regulation can be better performed according to the requirements of different tissue engineering support frames; the proper space and the intensity can be provided for the growth of the cells; the ordered space structure is formed.
