NAFION® is a DuPont Trademark for its perfluorosulfonic acid polymer.
The polymer has cation exchange properties and has excellent chemical stability similar to TEFLON®.
Unlike TEFLON® however, it adsorbs and swells in water due to the sulfonic acid terminated
side chains on the fluoropolymer backbone:
It has a wide variety of applications: from battery separators, to strong acid catalysis, to
artificial muscles. NAFION® is available from Ion Power in pellet, liquid dispersion, and membrane form.
Since 1999, Ion Power has been DuPont's officially appointed world-wide NAFION® distributor.
