摘要: 多面体笼型倍半硅氧烷( POSS)是由O-Si-O链接的纳米大小的笼型无机芯[(SiO1.5)n]和外围有机取代基团(活性或惰性)组成,这种独特的结构为杂化功能材料的制备提供了重要的平台与基础。本文从低介电材料结构对性能的影响,以及低介电性能的形成机理,综述了当前低介电材料制备方法,尤其是多面体笼型倍半硅氧烷( POSS)在低介电材料控制制备的研究进展,为该领域新材料设计提供借鉴。

关键词: 多面体寡聚倍半硅氧烷, 纳米复合材料, 低介电常数

Abstract: Polyhedral oligosilsesquioixanes (POSS) is a nanosized organic-inorganic hybrid molecule, which consists of a well-defined cage-like nano inorganic core [(SiO1.5)n] surrounded by organic corner groups. The unique structure of POSS molecules provide a an important platform for controllably preparation of hybrid nanocomposites in molecular level dispersion. In this paper, the influence of hybrid molecular structure on properties and forming mechanism of low dielectric constant, in particular, the research progress of POSS-based nanocomposite low dielectric constant materials were summarized.

Key words: Polyhedral oligomeric silsesquioxane(POSS), Nanocomposite, Low dielectric constant
