Ion exchange membranes: State of their development and perspective

“…Anion exchange functional groups can be either strongly basic, such as tertiary ammonium or weakly basic, such as primary, secondary or tertiary amine groups. Anion exchange membranes prepared by grafting of 4-vinylpyridine onto films, such as PTFE [64,65], PE [65,66], PP [67,68], ETFE [69], PVDF [70,71], penton [72] and polyvinyl chloride (PVC) [73] followed by quaternization with alkyl halide have been reported in literature.…”
