摘要:Low-dielectric-constant poly(acetoxystyrenezhi-co-octavinyl-polyhedral oligomeric silsesquioxane) (PAS-POSS) organic-inorganic hybrid nanocomposite was successfully synthesized via one-step free radical polymerization and characterized by FUR, high-resolution (1)H NMR, (29)Si NMR, DSC, TGA, AFM, spectroscopic ellipsometry and dielectric constants measurements. The results show T(g) and T(dec) were elevated dramatically due to the incorporation of inorganic POSS cores. Spectroscopic ellipsometry and dielectric constants measurement display the incorporation of POSS into PAS homopolymer can apparently reduce the dielectric constant of materials due to the increase of relative porosity of the hybrid nanocomposites.
