氟表面活性剂和氟聚合物(IX)——全氟磺酸树脂和全氟磺酸离子交换膜

全氟磺酸树脂(PFAR)及其前体全氟磺酰氟树脂(PFSR)，以及由其为基材制备的全氟磺酸离子交换膜(PFSIEM)是重要的氟化工产品，在氯碱工业、燃料电池、化工生产和国防安全等领域有重要应用。介绍了PFSR，PFAR和PFSIEM的发展历程、产品种类、制备方式、加工方法、表征方法和产品应用，并对其研究热点及我国在该领域的发展进行了展望。

Fluorinated surfactants and fluoropolymers (IX) Perfluorosulfonic acid resin and perfluorosulfonate ion-exchanged membrane

Perfluorosulfonic acid resin (PFAR) and its precursor, perfluorinated sulfonyl fluoride resin (PFSR), as well as perfluorosulfonate ion-exchanged membrane (PFSIEM) derived from them are important fluorinated chemical products. They play key roles in the fields of chlor-alkali industry, fuel cell, chemical production as well as national defense and state security. Herein, the development course, way for the preparation and method for the processing, the characterization methods as well as applications of PFSR, PFAR and PFSIEM were described. Finally, the focused points in the research work field as well as outlook for the development in China were presented.
