The process does not work on perfluorosulfonic acids such as PFOS. [237] A 2022 study published in Chemical Science shows breakdown of C-F bonds and their mineralization as YF 3 or YF 6 clusters. [238] Another study in the Journal of the American Chemical Society described the PFASs breakdown using metal-organic frameworks (MOFs). [239]
One of the most common and commercially available PEM materials is the fluoropolymer (PFSA) [2] Nafion, a DuPont product. [3] While Nafion is an ionomer with a perfluorinated backbone like Teflon, [4] there are many other structural motifs used to make ionomers for proton-exchange membranes. Many use polyaromatic polymers, while others use ...

Longer-chain perfluoroalkyl carboxylic acids, e.g. with five to nine carbons, are useful fluorosurfactants and emulsifiers used in the production of polytetrafluoroethylene (Teflon) and related fluoropolymers.
