固体表面接枝聚合物刷的研究与进展

New Approaches of the Polymer Brush Tethered on the Solid Substrate Surface

回顾了近年对固体表面接枝聚合物的有关研究,描述了聚合物刷的结构特征及其理论研究。重点介绍了由物理吸附法,"接枝到表面"法和"从表面接枝"法制备聚合物刷的路径和最新研究进展,并介绍了聚合物刷的应用。"从表面接枝"法是近年来研究聚合物刷的热点,不但可以用传统聚合法在一般固体表面接枝聚合物,还可以通过可控聚合或活性聚合在纳米颗粒表面接枝,实现无机-有机聚合物纳米复合材料的组装。

This article reviewed recent literatures on polymer brushes which attached to solid substrate surface. The characteristics of configuration, theories and applications on polymer brushes were introduced also. The synthetical methods and new novel progresses on the tethered polymer prepared by way of physisorption, ＂ grafting to＂ and ＂grafting from＂ were enumerated. ＂Grafting from＂ method was studied extensively these years, which was not only used to tether polymer on common solid surface but also attached polymer on nanoparticle with controlled polymerization or living polymerization to realize the assembly of inorganic-polymer nanocomposites.
