补充资料：电解食盐水溶液离子膜电解槽所用的膜材料之一
分子式：
CAS号：

性质：又称全氟羧酸-磺酸复合离子膜  Rf-COOH-Rf-SO3H  电解食盐水溶液离子膜电解槽所用的膜材料之一。使用时，将较薄的羧酸层面向阴极，较厚的磺酸层面向阳极，因而兼有羧酸膜和磺酸膜的优点。由于Rf-COOH层的存在，可阻挡氢氧离子返迁移到阳极室，确保了高的电流效率（96%），因Rf-SO3层的电阻低，能在高电流密度下运行，且阴极液可用盐酸中和，产品氯气中氧含量低，氢氧化钠浓度可达33%～35%。可在全氟磺酸膜上涂敷一层全氟羧酸的聚合物，或是将磺酸膜和羧酸膜进行层压，或是采用化学方法处理而制得的复合膜。现以采用化学方法处理者质量最佳。
