常见的芳香族聚酰胺复合反渗透（RO）膜易氧化，以N,N'-二甲基间苯二胺（DMMPD）为关键功能单体，与5-氯甲酰氧基间苯二甲酰氯（CFIC）反应，采用界面聚合技术制备了耐氯聚酰亚胺-聚氨酯RO膜材料。 X射线光电子能谱(XPS),测定了膜的耐氯性能,并分析了膜活性层的化学结构与耐氯性能的关系。
The common aromatic polyamide composite reverse osmosis(RO) membrane is easy to be oxidated.Chlorine resistance polyimide-urethane RO membrane material by interfacial polymerization technology was prepared with N,N′-dimethyl-m-phenylenediamine(DMMPD) as a key functional monomer which reacted with 5-choroformyloxyisophthaloyl chloride(CFIC).The surface chemical structures of membrane active layer were analyzed by combination of attenuated total reflectance infrared(ATR-IR) and X-ray photoelectronic spectroscopy(XPS),and the chlorine resistance performance of membrane was also measured.Furthermore,the relationship between chemical structure of membrane active layer and chlorine-resistant performance was analyzed.
