Aquivion(R) PFSA ionomer membranes are melt-extruded films based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-(CF2)2-SO2F industrially produced by Solvay Specialty Polymers. Following a film hydrolysis the perfluoropolymer's functional groups are operative in their sulfonic acid form, SO3H.
Synonyms: Aquivion(R) SO3H; Tetrafluoroethylene-perfluoro(3-oxa-4-pentenesulfonic acid) copolymer, Ethanesulfonic acid
Linear Structural Formula: [CF2CF(OCF2CF2SO3H)]m[CF2CF2]n
Application: Aquivion(R) PFSA membranes are used for electrochemical applications such as, but not limited to, polymer electrolyte fuel cells, electro-deionization systems, ozone generators, water electrolyzers, hydrogen separators and compressors, redox flow batteries as well as pervaporation or gas humidification systems.
