Nafion: Applications, Companies & Products

Nafion is a brand name for a sulfonated tetrafluoroethylene based fluoropolymer-copolymer synthesized in 1962 by Donald J. Connolly at the DuPont Experimental Station in Wilmington Delaware U.S. patent 3,282,875. Additional work on the polymer family was performed in the late 1960s by Walther Grot of DuPont. Nafion is a brand of the Chemours company. It…
