Tetrafluoroethylene-perfluoro(2-(2-sulfonylethoxy)propyl vinyl ether) copolymer

CAS: 31175-20-9

Tetrafluoroethylene-perfluoro(2-(2-sulfonylethoxy)propyl vinyl ether) copolymer (EPC) is a polymer that is synthesized by the polymerization of tetrafluoroethylene and perfluoro(2-(2-sulfonylethoxy)propyl vinyl ether). EPC has been shown to be effective in removing nutrients, such as phosphate and nitrate, from wastewater. The polymer can be used as an additive in the treatment of wastewater and perovskite. EPC has also been observed to reversibly form bilayers with water droplets or surfactant micelles. The FTIR spectroscopy revealed that the chemical structure of the copolymer includes fluorine, carbon, hydrogen, oxygen, sulfur, nitrogen, and chlorine. The microscopy showed that EPC forms a uniform film on glass slides when irradiated with UV light. The electrochemical impedance spect
