In order to develop a novel method for preparing perfluorosulfanate ion-exchange membranes, active species of the plasma reactions were analyzed by in situ mass spectroscopy. From the results, the reaction mechanism of the plasma polymerization and optimization of the preparation method were elucidated.1) Membranes prepared from benzenesulfonylchloride (BSC) monomer did not have ion-exchange capacity, whereas cation-exchange membranes can be prepared from benzensulfonylfluoride (BSF) monomer.2) From the results by in situ mass spectroscopy, it was demonstrated that the stability of an ionic-exchange situ of a monomer in plasma is a key point to prepare membranes with high ion-exchange capacities.3) C13-NMR results indicated that the plasma polymer had a highly cross-linked structure.

为了开发一种制备全氟磺酸离子交换膜的新方法，采用原位质谱分析了等离子体反应的活性物种。结果表明：1）以苯磺酰氯（BSC）为单体制备的膜不具有离子交换能力，而以苯磺酰氟（BSF）为单体制备的膜具有阳离子交换能力; 2）原位质谱分析结果表明，苯磺酰氟（BSF）为单体制备的膜具有较好的离子交换能力。结果表明，单体在等离子体中离子交换位置的稳定性是制备高离子交换容量膜的关键。3）C13-NMR结果表明，等离子体聚合物具有高度交联的结构。
