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
