接枝聚合改性的芳香聚酰胺复合反渗透膜及制备方法
摘要：
本发明公开了一种接枝聚合改性的芳香聚酰胺复合反渗透膜及制备方法，属于复合反渗透膜的制备技术。该接枝聚合改性的芳香聚酰胺复合反渗透膜表面通过接枝聚合反应带有3-烯丙基-5，5-二甲基海因聚合物。其制备过程包括：通过5，5-二甲基海因与烯丙基溴反应制备得到单体3-烯丙基-5，5-二甲基海因；采用偶氮二异丁脒盐酸盐为引发剂通过接枝聚合的方法将3-烯丙基-5，5-二甲基海因引入到芳香聚酰胺复合反渗透膜的表面，制备得到接枝聚合改性的芳香聚酰胺复合反渗透膜。本发明过程简单，所制得的接枝聚合改性的芳香聚酰胺复合反渗透膜同时具有耐氯和抗微生物污染性能。
摘要（英）：

The invention discloses an aromaticpolyamide composite reverse osmosis membrane modified by graft polymerization and a preparation method thereof, belonging to a preparation technology of composite reverse osmosis membranes. The surface of the aromaticpolyamide composite reverse osmosis membrane modified by graft polymerization is provided with a 3-allyl-5,5-dimethylhydantion polymer. The preparation method comprises the steps of: reacting 5,5-dimethylhydantion with allyl bromide to prepare the 3-allyl-5,5-dimethylhydantion polymer as a monomer; and introducing the 3-allyl-5,5-dimethylhydantion polymer into the surface of the aromaticpolyamide composite reverse osmosis membrane by adopting zaodiisobutyronitrile amidine hydrochloride as an initiating agent through using a graft polymerization method to prepare the aromaticpolyamide composite reverse osmosis membrane modified by graft polymerization. The invention has simple process; and the prepared aromaticpolyamide composite reverse osmosis membrane modified by graft polymerization has properties of resisting chlorine and preventing microbial contamination.
