A novel fluorinated poly(aryl ether oxadiazole)s ionomer with quaternary imidazole groups were synthesized via copolymerization of 3,3′,5,5′-tetramethy biphenyl diphenol(TM-BP),2,5-bis(2,3,4,5,6-pentafluorophenyl)-1,3,4-oxadiazole(FPOx)and 6F-BPA,bromination of the benzylic methyl,and functionalization with N -methylimidazole. The anion exchange membranes(QFOAEMs)were obtained by solution casting method. The ion exchange capacity(IEC),conductivity,water uptake and swelling ratio of the QFOAEMs were studied. The results showed that the permeability of vanadium ion of QFOAEMs was 1.1×10-8cm2·min-1,much less than that of Nafion117 membrane(3.8×10-7cm2·min-1). The QFOAEMs membrane has a potential application for vanadium redox flow battery.
