Beschreibung
Zusammenfassung:	An integral composite membrane is provided including a porous polymeric membrane impregnated with a perfluoro ion exchange material to make the micropores of the membrane occlusive and a surfactant having a molecular weight greater than 100 wherein the thickness of the composite membrane is less than 0.025 mm. Methods for making and regenerating the integral composite membrane are also provided.
