Organosoluble polyimide/silica hybrid materials were prepared using the sol-gel process. The organosoluble polyimide was based on pyromellitic anhydride (PMDA) and 4,4Ј-diamino-3,3Ј-dimethyldiphenylmethane (MMDA). The silica particle size in the hybrid is increased from 100 -200 nm for the hybrid co
Polyimide-silica (PI-SiO 2 ) hybrids with a nanostructure was obtained using the nonaqueous sol-gel process by polycondensation of phenyltriethoxysilane in a polyamic acid solution. Self-catalyzed hydrolysis of phenyl-substituted akoxysilane and modification on the polyimide structure are applied an
