With regard to anion exchange membranes,the traditional preparation method involves a much complicated process—chloromethylation,in which the commonly used chloromethyl methyl ether and bis-chloromethylether are now considered carcinogens.Therefore,it is necessary to develop new routes to prepare anion exchange membranes without such chloromethylation process.As for cation exchange membranes, mostly-perfluorinated sulfonic acid ionomers,such as Nafion~?

对于强碱性的阴离子交换膜的制备，由于传统路线中的卤甲基化步骤中不可避免的采用强致癌物质二氯甲醚，因此无论是从经济成本还是环境保护方面，开发不采用氯甲基化步骤的阴离子交换膜制备方法是目前的一个迫切要求。
