Polymeric membrane processes including ultrafiltration (UF) and reverse osmosis (RO) are widely used in water purification and desalination because of their simple operation and energy efficiency. However, polymeric membranes are prone to organic fouling such as oily wastewater. Since the membrane fouling leads to decline of water flux, physical and/or chemical cleaning processes or membrane surface modifications should be required to reduce the membrane fouling. Conventional surface modifications have some drawbacks such as harsh modification condition and material-specific. Recently, dopamine has been an attractive reagent can be easily coated on universal substrate and also show the improved anti-fouling properties. Despite its outstanding performance, dopamine modified membranes have poor resistance to chlorine as a commonly used oxidizing agent. Here, we demonstrate a highly chlorine-tolerant dopamine based surface modification using cross-linked poly(ethylene glycol) diacrylate. |
