这篇专题文章介绍了光诱导活性表面接枝聚合的基本化学和应用。讨论了聚合物基质惰性烷基C-H键的活化机理、活性自由基和可逆休眠物种的结构、接枝链的生长方式(包括直链、支链和交联体)以及空间效应的作用。介绍了一步法和两步法两种工艺的特点及其在制造图案精确可控、功能要求高的聚合物刷、平面基板上支链和嵌段接枝链以及聚合物层压等方面的应用。还介绍了三维共价键合聚合物颗粒的制备，如纳米级聚合物颗粒单分子膜(均匀分布和双峰分布)、微米级的离散固体和中空聚合物颗粒以及在聚合物衬底上的多层聚合物颗粒。最后总结了光诱导活性表面接枝聚合在非平面表面改性中的应用，如制备核-壳聚合物粒子、Janus粒子和具有毛状高分子链的交联水凝胶。
This feature article covers the fundamental chemistry and applications of photo-induced living surface grafting polymerization. The mechanism of activation of inert alkyl C–H bonds of polymer substrates, the structures of the active free radical and reversible dormant species, the modes of the grafting chain growth (including linear, branched and cross-linked variants), and the role of spatial effect are discussed. Two technologies, i.e., 1-step and 2-step processes, their features and applications in fabricating polymer brushes with precisely controlled patterns, desired functions, branched and block grafting chains on planar substrates, and polymer lamination are presented. The fabrication of 3-dimensional covalently bonded polymer particles, such as nano-sized polymer particle monolayers (with uniform and bimodal distributions), discrete solid and hollow polymer particles of micrometer size, and multilayer polymer particles on polymeric substrates are also introduced. In the last part, the application of photo-induced living surface grafting polymerization in non-planar surface modifications, such as the preparation of core–shell polymer particles, Janus particles and cross-linked hydrogels with hairy polymer chains is summarized.
