文摘

Nanocomposite properties were metal alkoxide and polyimide COOH dependent. Polyimide COOH–Ti interactions reduced chain mobility and led to crosslinking. TiO2 domain size and polyimide compatibility was greater than SiO2. SAXS and TEM revealed that TiO2 formed smaller domains than SiO2. Material FFV increased 38% with TiO2 but changed little with SiO2.
