    • 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.
    • 具有高耐污性的选择性膜。 在一个实施方案中,选择性膜是具有通过将亲水性化合物共价键合到聚酰胺膜而制备的亲水性涂层的复合聚酰胺反渗透膜,所述亲水性化合物包括(i)适于与聚酰胺直接共价键合的反应性基团 膜,反应性基团是伯胺和仲胺中的至少一种; (ii)非末端羟基; 和(iii)酰胺基。 在另一个实施方案中,亲水性化合物包括(i)适于与聚酰胺膜直接共价键合的反应性基团,反应性基团为伯胺和仲胺中的至少一种; (ii)羟基; 和(iii)酰胺基,酰胺基通过烷基和烯基之一直接与羟基连接。
