The 4-vinylbenzyl chloride(VBC)-co-styrene(St)-co-2-hydroxyethyl acrylate (HEA) copolymer (VSH) was synthesized by solution copolymerization. The quaternary ammonium groups () were introduced in the VSH copolymer by amination reaction. The anion-exchange membrane, various of different crosslinking agent contents, was prepared by casting method on the glass plate. The chemical structure and thermal properties of copolymers were investigated by FT-IR, TGA and DSC. And than, the water uptake, electric resistance, ion exchange capacity and ion conductivity of anion-exchange membranes were characterized by wet method and instrumental analysis. And also, the charge-discharge efficiency of membrane was measured by Voltmeter. |
