The research of shape memory polymer is a hot topic in the field of smart polymers. In recent years, as an important kind of shape memory polymers, the light-induced shape memory polymers have attracted great interest from researchers due to their unique properties. In this article, the progress in light-induced shape memory polymers is reviewed. The unique advantages, memory mechanism, applications and research trend of the shape memory polymers are introduced. In terms of the shape memory mechanism, light-induced shape memory polymers can be divided into two types, one is based on photochemical reactions, the other is based on light- induced heating. The shape memory polymers based on the two memory mechanisms are reviewed in detail. The applications of these materials are also discussed. Finally, the problems in light-induced shape memory polymers are pointed out, and the future development and applications of the polymers are prospected.
