Abstract: A high-oxidation and NOx-free synthesis of graphene oxide (GO) from natural graphite using the modified Hummers' method is described. The amine-functionalized GO using dodecylamine (DDA) is used as a filler for membranes for the first time. Antifouling and antibacterial properties of UF membranes are achieved using amine functionalization of GO. A process of incorporating raw GO and dodecylamine-functionalized GO (GO-DDA) in polysulfone (PSF) via phase inversion technique is disclosed.
