Abstract

New polyimide–silica hybrid materials were prepared using the polyamic acid synthesized by copolymerization of 3, 3′, 4, 4′-benzophenonetetracarboxylic dianhydride (BTDA), 4, 4′-oxydianiline (ODA) and an A2A′-type tri-functional amine, 1, 1-bis (4-(aminophenoxy) phenyl)-1-(4-(4-amino-2-trifluoromethylphenoxy) phenyl) ethane (1)(BTDA: ODA: 1= 7: 6: 1 in the molar). 3-(Triethoxysilyl) propyl succinic anhydride (TESSA) was reacted with amino ...
