摘要
通过界面聚合方法,将功能单体N,N'-二甲基间苯二胺(DMMPD)与多元酰氯5-氯甲酰氧基-异肽酰氯(CFIC)聚合,制得一种耐氧化的聚酰亚胺-氨酯反渗透复合膜.采用全反射傅里叶变换红外光谱(ATR-FT-IR)和X射线光电子能谱(XPS)分析了膜活性层的化学结构,考察了膜的耐氧化性能,并探讨了膜活性层化学结构与膜抗氧化性能之间的关系.
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.
