Beschreibung
Zusammenfassung:The invention provides membranes useful for filtration of water and other liquids. The membrane may be a composite membrane having a polymer layer incorporating quaternary phosphonium or ammonium groups. The polymer layer may be resistant to protein adsorption in an aqueous environment. The membrane may also be a surface-modified membrane in which a polymer having quaternary phosphonium or ammonium groups is covalently attached to the membrane surface. Methods for making and using the membranes of the invention are also provided.
