摘要
本文综述了近年来在线形聚合物、树枝状大分子及树枝化聚合物等不同聚合物的每个重复单元上,高密度地、通过不同联接方式接枝上新的聚合物侧链而形成的刷形接枝共聚物,即聚合物分子刷的研究进展。主要介绍聚合物分子刷的三种合成途径,即“大单体聚合法”,“从主链接枝法”及“接枝到主链法”,并对不同路线的特点进行分析,同时对分子刷在制备纳米杂化材料、纳米导线及智能材料等方面的应用进行了综述。
This article highlights the recent development of synthesized polymer molecular brushes, which are formed by high-densely attaching polymers via different strategies to linear polymers, dendrimers or dendronized polymers. Three different synthetic methods for molecular brushes, e. g. ＂grafting through＂, ＂grafting from＂ and＂grafting to＂ are detailed and compared based on the achievable molar mass and structure perfection of the resulted molecular brushes, together with some conformation dependence. Some reports on the synthesis and conformational study of peptide brushes and thermally switchable polymer brushes were also included. The applications of molecular brushes in different areas, such as nano-materials for surface modification and nano-wires are also introduced briefly.
