A novel partially fluorinated anion exchange membranes were synthesized using vinylimidazole (VI), trifluoroethylmethacrylate (TFEMA) and divinylbenzene (DVB) by solution polymerization. The structure of membranes was confirmed by FT-IR and 1H-NMR spectrometer. The membrane properties such as bursting strength, thermal property, chemical resistance, water content, ion exchange capacity, electrical resistance and ion conductivity were measured. The maximum values of bursting strength, ion exchange capacity and ion conductivity were 4.53 kgf/cm2, 1.92 meq/g dry and 0.0088 S/cm, respectively. The minimum values of water content and electrical resistance were 3.33% and 1.25 Ω • cm2, respectively. The chemical resistances of membranes were better than that of commercial membrane (AMX). |
