Gelatin/polypyrrole (Gel/PPy) with photo-sensitive and controlled release properties was prepared by chemical polymerization based on the light absorption characteristics of polypyrrole and the temperature-sensitive spiral-irregular crimp structure of gelatin.The hydrogel was compounded,and carbendazim was used as a template drug to investigate the controlled release of the gel system.The results showed that polypyrrole could effectively compound with gelatin,and acted as a crosslinking agent to enhance the mechanical strength of the gel.Increasing temperature can promote the release of carbendazim.Under the condition of light for 3 hours,the system could achieve effectively controlled release of carbendazim,and the release rate increased with the decrease of the crosslinker content.
