光诱导的RAFT聚合研究进展

Progress in photoinduced RAFT polymerization

目的综述光诱导的RAFT聚合的研究进展,为聚合物材料分子设计提供参考。方法参考国内外相关文献30余篇,对紫外光(UV)诱导的RAFT聚合和可见光诱导的RAFT聚合研究进展进行阐述。结果总结了光诱导的RAFT聚合的现状及问题。结论开发低强度、红外/近红外等柔和的光引发体系和类似于生物体系中单体精确调控的聚合过程将是未来发展的方向。

Purposes—To review the progress in the research of photoinduced reversible addition-fragmentation chain transfer polymerization(RAFT)and to provide a reference for molecular design of polymer materials.Methods—More than 30 relevant literature at home and abroad were summarized,the progress in research of UV-induced RAFT polymerization and visible-light-induced RAFT polymerization was introduced.Result—The current situation and problems of photoinduced RAFT polymerization are summarized.Conclusion—The development of softer irradiation sources such as low light intensity and infrared/near-infrared light wavelengths,and RAFT polymerization system that resembles self-regulatory and biological processes will be the future development directions.
