Imidazole salt polyionic liquid modified polyvinylidene fluoride charged membrane and preparation method

摘要: The invention provides a preparation method of an imidazole salt polyionic liquid modified polyvinylidene fluoride (PVDF) charged membrane. adopts P(PEGMA-co-BVImBr) as the additive for blending modification PVDF into membrane, thus obtaining salt-containing synthesis random copolymer is simple, also immersion-precipitation phase transformation employed to prepare and has characteristics no need pore-forming agent, mild reaction conditions, easy realization, few needed operation steps, simple operation, easier industrial production, membrane wide applicationrange, structure not destructed, membranes good stability.
