An Overview of Photopolymerization and Its Diverse Applications

Abstract

Photopolymerization is an energy‐saving and environmentally friendly technology and has been widely applied and continuously developed in various fields since the mid‐20th century. Today, photopolymerization technology has become ubiquitous in every aspect of our lives. This review initially explains the principle of photopolymerization reactions, introducing the process of photopolymerization and the initiation mechanisms of photoinitiators. Then, this review focuses on the applications of photopolymerization technology in thiol‐based click reactions, photoinduced controlled/living polymerizations, 3D printing, ultraviolet (UV) nanoimprint lithography photoresist and hydrogels to demonstrate its irreplaceable role at present.
