제목 Synthesis and characterization of branched and fluorinated poly(arylene ether sulfone) electrolyte membranes for fuel cell applications
초록 This report describes the preparation and characterization of branched and sulfonated poly(arylene ether sulfone) copolymer (PAES) membranes containing perfluorocyclobtane moieties. Two different monomers, 4,4'-bis(trifluorovinyloxy)biphenyl, 4,4'-sulfonyl-bis(trifluorovinyloxy)biphenyl and a brancher 1,1,1-tris(4'-trifluorovinyloxyphenyl)ethane were synthesized through fluoroalkylation and Zn-mediated dehalogenation. They were then terpolymerized through thermal [2π+2π] cycloaddition. The branching degree of the terpolymers were controlled by the brancher content. Lastly they were post-sulfonated with chlorosulfonic acid. Their properties such as water uptake, ion exchange capacity and ion conductivity were observed in terms of sulfonation degree and branching degree.
