Synchronous crosslinking imidized polymer electrolytes having fully interpenetrating polymer networks (full-IPNs) structure for application in membrane fuel cell

Polymer electrolyte films having fully interpenetrating polymer networks (Full-IPNs), composed of styrene-maleic anhydride alternating copolymer (PSMAn) and isobutylene-maleic anhydride alternating copolymer(PisoMAn), have been prepared by using 2,2'-benzidinedisulfonic acid(BDSA) as the imidizing crosslinker. The resulting films were characterized by using TGA, EA, IEC, water uptake, and proton conductivity. The purpose of this work deals with the synchronous crosslinking imidization reaction of between polymers as a synthetic method, in order to prepare novel heat-resistant polymer electrolytes for application in membrane fuel cell.
