    • PURPOSE: An anion-exchange composite membrane is provided to ensure low electric resistance, and excellent ion-exchange capacity, mechanical property, chemical property and processability, and to facilitate ion-exchange capacity and ion conductivity by controlling the composition of a styrene-based monomer and vinylbenzyl-based monomer. CONSTITUTION: A method for preparing an anion-exchange composite membrane comprises the steps of: impregnating a porous film in a polymerization solution including a styrene-based monomer, vinyl benzene-based monomer, crosslinking agent and initiator; polymerizing the impregnated porous film to prepare a styrene-vinyl benzene-based copolymer composite film; and reacting tertiary amine with the styrene-vinyl benzene-based copolymer and then introducing quaternary ammonium group as a negative ion exchanger.
    • 目的:提供阴离子交换复合膜,以确保低电阻,优异的离子交换能力,机械性能,化学性能和加工性能,并且通过控制苯乙烯基的组成来促进离子交换容量和离子传导性 单体和乙烯基苄基系单体。 构成:制备阴离子交换复合膜的方法包括以下步骤:在包括苯乙烯基单体,乙烯基苯类单体,交联剂和引发剂的聚合溶液中浸渍多孔膜; 聚合浸渍的多孔膜以制备苯乙烯 - 乙烯基苯基共聚物复合膜; 并使叔胺与苯乙烯 - 乙烯基苯基共聚物反应,然后引入季铵基团作为负离子交换剂。
