发明名称 SELECTIVE MEMBRANE HAVING A HIGH FOULING RESISTANCE
摘要 A selective membrane having a high fouling resistance. In one embodiment, the selective membrane is a composite polyamide reverse osmosis membrane having a hydrophilic coating made by covalently bonding a hydrophilic compound to the polyamide membrane, the hydrophilic compound including (i) a reactive group that is adapted to covalently bond directly to the polyamide membrane, the reactive group being at least one of a primary amine and a secondary amine; (ii) a non-terminal hydroxyl group; and (iii) an amide group. In another embodiment, the hydrophilic compound includes (i) a reactive group adapted to covalently bond directly to the polyamide membrane, the reactive group being at least one of a primary amine and a secondary amine; (ii) a hydroxyl group; and (iii) an amide group, the amide group being linked directly to the hydroxyl group by one of an alkyl group and an alkenyl group.
