表面光接枝聚合反应新进展

Recent developments in UV-induced surface graft polymerizations

表面性能对高分子材料应用至关重要,但多数聚烯烃材料表面惰性,需对表面进行改性或功能化.紫外光引发表面光接枝聚合反应具有诸多优势,因而获得广泛应用.作者以本实验室近年的研究为基础,结合这一领域国际上的部分重要研究成果,概述了实施表面光接枝聚合反应的一些新方法:控制/活性表面光接枝聚合、自引发光接枝聚合、暗区表面光接枝聚合、表面光接枝-交联聚合以及表面小分子光化学反应等.

Polymer surfaces play a big role in polymer materials properties and applications. Because of the highly inert surfaces, a majority of polymer materials need surface modification and functionalization. UV-induced surface graft polymerization is obviously advantages over other methods for surface graft modification and thus has found a great number of practical applications. This review is designed to introduce the latest developments in UV-induced surface graft polymerizations and polymeric materials surface modifications, mainly according to our own investigations and also referring to some important achievements from others. This article covers the following contents： controlled/living surface graft polymerizations, self-initiated surface graft polymerizations （i.e., surface graft polymerizations in the absence of photoinitiators）, unable-to-be-irradiated surface graft polymerizations, surface graft/cross- linking reactions, and surface photochemical reactions. The last section was dedicated to discuss the relevant intractable problems. This review is expected to speed up the progress in the intriguing research field： polymeric materials surface modification and functionalization.
