The IPA-co-HDO-co-(TPA/MA) copolymers for all vanadium redox-flow battery were synthesized by melt condensation polymerization using isophthalic acid(IPA), 1,6-hexandiol(HDO), terephthalic acid(TPA) and maleic anhydride(MA).The amination of chloromethylated IPA-co-HDO-co-(TPA/MA)(CIHTM) copolymer was carried out using trimethylamine, and the anion exchange membrane was prepared by UV curing reaction. The structure and thermal stability of IHTM copolymers were confirmed by FT-IR, 1H-NMR and TGA analysis. Properties of the anion membrane such as water uptake, ion exchange capacity, electric resistance and electrical conductivity were measured by gravimetry, titration and LCR meter. The efficiency of the all-vanadium redox flow battery was carried out. |
