摘要

多面体低聚倍半硅氧烷(POSS)是新兴的有机/无机杂化材料，其特殊的笼状结构可以从纳米尺度上影响聚氨酯体系的结晶行为、微相分离程度、交联密度等结构特征。少量添加即可大幅提高聚氨酯的耐水性、热稳定性、力学性能，以及阻燃性能、黏结性能、韧性等。本文从POSS/聚氨酯复合材料的结构出发，介绍了化学合成POSS基聚氨酯及物理共混POSS/聚氨酯复合材料，总结分析了悬垂型、星型、串珠型以及物理混合 POSS基聚氨酯复合材料的结构特点，以及POSS结构差异对其复合材料性能的影响与影响机理。

Abstract

Polyhedral oligomeric silsesquioxanes (POSS) as a new kind of organic-inorganic hybrid materials with special cage-like structure

has an effect on the crystallization behavior

degree of micro-phase separation and crosslinking density of the polyurethane system. It has been demonstrated that incorporation of small amounts of POSS into PU can significantly enhance the water resistance

thermal stability and mechanical properties. This article reviews some new insights into the relationship between the performance of POSS/PU nanocomposites and the structure of different POSS such as pendants

starburst

beaded and physical blend.
