Nafion an overview | ScienceDirect Topics

Nafion is a sulfonated tetrafluoroethylenebased fluoropolymer–copolymer with conductive properties. Due to the presence of perfluoroalkyl backbones in Nafion, it has high hydrophobicity properties, hence making it an effective matrix to disperse graphene in an aqueous solution [53].Nafion was used as an electrode modifier for sensor electrode fabrication [54].
