The poly(vinylimidazole-co-trifluoroethylmethacrylate-co-divinylbenzene)(QPVTD) copolymers were synthesized by solution polymerization. The quaternization of PVTD copolymers were carried with functionalizing reagents such as 1-bromo-2-methylpropane, 1-bromobutane, 1-bromo-3-methylbutane, 1-bromopentane. The QPVTD anion exchange membranes were prepared by the casting method. The chemical structure of the membranes were confirmed by FT-IR, 1H-NMR spectrometer. The membrane properties such as water content, ion exchange capacity, electrical resistance and ion permselectivity for nitrate were measured. The maximum water uptake, electrical resistance and ion exchange capacity were 60.85 %, 8.0 Ω/cm2 and 1.25 meq/g, respectively. |
