Research and Progress of Photosensitive Polymer Hydrogel

In recent years, much attention is paid to the photosensitive polymer hydrogel, a kind of intelligent polymer hydrogels by scientists all over the world. The development of photosensitive intelligent polymer hydrogel is introduced in this paper. The mechanisms of photosensitivity, types and status of application of the hydrogels are described in detail, and the prospect of the application research and development of it are also recommended.
