摘　　要：笼型倍半硅氧烷(POSS)是一种由Si—O—Si键构成的高度对称笼型结构、端基具有极高的可设计性及高反应性新型有机-无机杂化材料,空间尺寸1～3nm;选取带有特定结构的光、电、磁等特性单元,利用活性聚合的方法可制得不同形状的POSS-Polymer杂化材料,通过溶剂、热、电、纳米印刷等方法"梳理"分子链结构,使之成为长程有序的纳米序列结构材料,获取具有预期结构和功能特性的高分子实体。本文从分子自组装的角度对两亲性笼型倍半硅氧烷(POSS)杂化高分子材料进行了介绍,分析了其在生物医药用高分子、智能高分子及低介电高分子材料等多个领域内的最新研究进展,并对今后的发展做了相关的预测与展望。Polyhedral Oligomeric Silsesquioxane （POSS） are hybrid organic-inorganic nanoparticles with a 3D cage structure, i. e. , by a polyhedral Si--O--Si nanostruetured skeleton, surrounded by several organic groups linked to silicon atoms by covalent bonds which have high designability and high reactivity. Variety of POSS-Polymer hybrid materials can be prepared by selecting specific optical, electrical,magnetic and other characteristics of the unit through living polymerization method. Long range ordered nanometer structure materials are obtained by ＂combing＂ structure of molecular chain through solvents, heat, electricity, and the nanoprinting methods, obtaining the expected sequence, structural and functional polymers. This article introduces the self assembly of amphiphilic POSS hybrid polymer materials, analyzes the latest advances in research of the biological medical polymer, intelligent polymers and electro-active polymer materials ,forecasts and prospects the development in the future.
