Abstract:Water scarcity has driven increased research on enhancing reverse osmosis (RO) membranes. Current research methods are time-consuming and not suitable for industrial applications. In this study, a more uniform PA layer with high hydrophilicity was prepared by utilizing dimethyl sulfoxide (DMSO) to optimize the interfacial polymerization process and 4-dimethylaminopyridine (DMAP) in postprocessing to improve water adsorption and transport. Characterization and molecular dynamics simulations showed that DMSO enh… Show more
