    • A preparation method of a polyamide thin film composite reverse osmosis membrane and a polyamide thin film composite reverse osmosis membrane prepared using the preparation method are provided. The preparation method of a polyamide thin film composite reverse osmosis membrane using interfacial polymerization of an amine aqueous solution and amine-reactive compound includes the steps of (a) forming an active layer through interfacial polymerization by contacting a surface of a porous support with an amine aqueous solution containing a polyfunctional aromatic amine monomer and an organic solution containing polyfunctional acyl halide monomer as an amine-reactive compound, and (b) performing post-treatment preceded by the forming of the active layer by contacting the active layer with an aqueous solution containing 0.1 to 100 wt % of polyfunctional tertiary alcohol amine. The polyamide thin film composite reverse osmosis membrane prepared by using the polyfunctional tertiary alcohol amine as a post-treatment compound has improved water permeability and salt rejection compared to a case of using various post-treatment agents or methods.
    • 提供了使用该制备方法制备的聚酰胺薄膜复合反渗透膜和聚酰胺薄膜复合反渗透膜的制备方法。 使用胺水溶液和胺反应性化合物的界面聚合的聚酰胺薄膜复合反渗透膜的制备方法包括以下步骤:(a)通过界面聚合形成活性层,通过使多孔载体的表面与胺 含有多官能芳族胺单体的水溶液和含有多官能酰卤单体作为胺反应性化合物的有机溶液,和(b)在活性层形成之前进行后处理,所述活性层通过使活性层与含有 0.1〜100重量%的多官能叔胺胺。 通过使用多官能叔醇胺作为后处理化合物制备的聚酰胺薄膜复合反渗透膜与使用各种后处理剂或方法的情况相比,具有改善的透水性和耐盐析性。
