The invention discloses a homogeneous anion exchange membrane and a preparation method thereof. The method firstly dissolves 4-vinylbenzyltrimethylammonium chloride SMS and dimethylaminoethyl methacrylate DMAEMA in a solvent to form a homogeneous solution , and add a cross-linking agent and an initiator to initiate polymerization and cross-linking at a certain temperature. After the reaction is completed, add 1,4-p-dichlorobenzyl XDC, and carry out a secondary cross-linking reaction at an appropriate temperature to obtain a homogeneous film casting solution. After scraping the membrane, the solvent is dried to obtain a homogeneous anion exchange membrane. The homogeneous anion exchange membrane prepared by the invention has low resistance, high ion migration number, high current efficiency and low energy consumption in the electrodialysis process, and the preparation method has simple process and can realize industrialized continuous production. |
