Abstract
Photopolymerization as an
energy-saving and environment-friendly technology has been applied in
many fields and developed continuously since the middle of the 20th
century. Today, photopolymerization technology is ubiquitous in every
aspect of our lives. This review starts from the principle of
photopolymerization reaction, introduces the process of
photopolymerization, initiation mechanism of photoinitiators and three
kinds of polymerization methods according to the wavelength of
irradiation source. Subsequently, review focuses on the application of
photopolymerization technology in thiol-based click reaction, 3D
printing, photoresist, hydrogels and other fields, so as to demonstrate
its irreplaceable role in the present.
