Abstract: 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.

Key words: N,N′-Dimethyl-m-phenylenediamine(DMMPD), 5-Choroformyloxyisophthaloyl chloride(CFIC), Polyimide-urethane, Chemical structure, Chlorine resistance performance
