The vinylimidazole(VI)-co-trifluoroethylmethacrylate(TFEMA)-co-divinylbenzene(DVB) copolymer was synthesized using by the solution polymerization. The copolymer was functionalized with such as 1bromo-2-methylpropane, 1bromobutane, 1bromo-3-methylbutnae, 1brmopentane and QPVTD anion exchange membranes were prepared by the casting method. The chemical structure of the membrane was confirmed by FT-IR, 1H-NMR spectroscopy. 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%, 8.0Ω/cm2 and 1.25meq/g dry respectively. |
