Easy Fabrication of Reverse Osmosis Membrane with High and Anti-biofouling and Chlorine Resistance Properties

摘要：

　　N-halamine precursor P(ADMH-co-VAm) was used to improve thin-film-composite polyamide (PA) reverse osmosis (RO) membrane antibacterial and chlorine resistance properties through second interfacial polymerization process.The modification procedure is easy and the resultant membrane shares similar permselectivity with some commonly used RO membranes, higher than the virgin membrane;meanwhile, it demonstrates significantly improved anti-biofouling and chlorine resistance properties.P(ADMH-co-VAm) on the membrane surface plays as sacrificial layer when membrane suffers from chlorine attack, protecting the selective PA sub-layer intact.After chlorination, P(ADMH-co-VAm) transfers into N-halamine antibacterial polymer, which endows the membrane with potent antibacterial performance.
