PET-RAFT polymerization (Photoinduced Electron Transfer-Reversible Addition-Fragmentation Chain Transfer Polymerization) has been widely concerned and applied in the field of polymerization due to its characteristics such as low energy consumption, mild reaction conditions, time-space control, reaction orthogonality and oxygen resistance. In terms of surface modification, PET-RAFT polymerization is used to improve the surface characteristics of materials, such as biocompatibility and anti-adhesion. In the biomedical field, PET-RAFT polymerization technology is used to prepare drug delivery systems such as spherical micelles and vesicles. In addition, the application of PET-RAFT polymerization in 3D printing and laser writing demonstrates its great potential for precise control of material structure and functionalization. The key to PET-RAFT polymerization is to find suitable photocatalysts. Currently, the types of catalysts include homogeneous catalyst systems, such as transition metal complexes, porphyrin and phthalocyanine catalysts, organic dyes, and semiconductor materials, as well as heterogeneous catalyst systems, such as macro material supported, nano material supported, metal organic framework, co valent organic framework, conjugated microporous polymers, etc. Among them, heterogeneous catalysts can be effectively recovered and utilized by centrifugation and filtration separation of photocatalysts.The heterogeneous catalyst can be effectively recycled by centrifugation and filtration separation. In the future, researchers will develop new low cost, high efficiency, easy recovery, non-toxic photocatalysts to improve the use of low energy photons and improve the compatibility of photopolymerization with the environment.
