Abstract:
1. A polymer electrolyte membrane comprising an interpenetrating polymer network comprising: the crosslinked product of a polyimide having a reactive terminal group; and an ion conductive polymer, wherein the crosslinked product of the polyimide is formed in the presence of the ion conductive polymer to thereby form the interpenetrating polymer network, and wherein the polyimide is a compound having a repeating unit represented by Formula 1 below: where m is in the range of 0.01 to 1, n is in the range of 0 to 0.99, and m+n=1; average copolymerization p is in the range of 10 to 10,000; X and X′ are each independently Y and Y′ are each independently X R Q and Q′ each independently represent simply a chemical bond or are each a group selected from the group consisting of —O—, —CO—, —SO Z and Z′ are each independently selected from C, Si, Ge, Sn, and Pb; and E is a univalent reactive terminal group having a carbon-carbon double bond or triple bond, derived from a monoamine compound or monoanhydride compound.
