发明名称 COMPOSITE POLYAMIDE MEMBRANE DERIVED FROM AROMATIC MONOMER INCLUDING ANHYDRIDE AND SULFONYL HALIDE FUNCTIONAL GROUPS
摘要 A method for making a composite polyamide membrane including the step of applying a polyfunctional amine monomer and polyfunctional acyl halide monomer to a surface of the porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, wherein the method is characterized by: i) conducting the interfacial polymerization in the presence of an aromatic anhydride monomer include at least one sulfonyl halide functional group, or ii) applying the aromatic anhydride monomer to the thin film polyamide layer.
