Thin-film composite (TFC) membrane is currently the most widely used membrane structure for reverse osmosis (RO) process. Most commercial membrane for RO consisted of porous support layer and dense polyamide permselective layer, yet the polyamide layer has a very rough surface morphology and considerable thickness, and these features are intrinsic properties of current RO membrane fabrication process. In this study, we present the new membrane fabrication, named layered interfacial polymerization (LIP). LIP could control the roughness and thickness of permselective layer without complicated process or significant membrane performance loss, and the performance itself was comparable to conventional IP membrane. Moreover, the fabricated membrane has a remarkable antifouling ability possibly due to the unique smooth morphology.
