In this study, proton exchange membranes are prepared from poly(arylene ether ketone) having long pendant sulfoalkyl groups as proton conductor for the membrane of all vanadium redox flow battery system. Sulfonated PAEK with flexible side chain were prepared by polycondensation of 4,4-Difluorobenzophenone with 2,2-Bis(3-amino-4-hydroxyphenyl)hexafluoropropane and Bisphenol-AF, followed by post-sulfonation using 1,3-butanesultone. We confirmed the structure by using H1-NMR, FT-IR. And the properties of membrane such as ion conductivity, ion exchange capacity were tested for all vanadium redox flow battery applications. |
