Synthesis of perfluorinated ionomers and their anion exchange membranes

Perfluorinated ionomers (S-PFSO2NH-GCI-OH) and their anion exchange membranes (AEMs) were successfully synthesized from short side-chain perfluorosulfonamide polymer for the first time. S-PFSO2NH-GCI-OH ionomers well dissolved in many solvents, especially in low-boiling point solvents and formed a transparent solution. The wet membrane of S-PFSO2NH-GCI-OH displayed a well defined nano-phase separated structure with the ionic cluster dimension of...
