An anion-exchange membrane based on vinylbenzyl chloride/ethylmethacrylate/styrene monomer (VBC/EMA/SM) terpolymer was prepared with radical polymerization and amination reaction for various amination times. Structure of aminated VBC/EMA/SM anion-exchange membranes were characterized with Fourier-transform infrared (FTIR) spectrometry. The molecular weight and thermal stability were obtained with gel permeation chromatography (GPC) and thermogravimetric analysis (TGA). The basic properties such as water uptake, ion exchange capacity and electrical resistance were measured. The values of ion exchange capacity, water uptake, electrical resistance and molecular weight of synthesized anion-exchange membrane were 1.4 meq/g, 31.5 %, 1.92 Ω․cm2 and 3.3 ×104 g/mol, respectively. The morphology of membrane was observed with scanning electron microscope (SEM). |
