Improving membrane durability associated with resistance to chlorine and biofouling is critical important for polyamide (PA) reverse osmosis (RO) membrane technology. Here, few-layered TiO2 nanoparticles and graphene oxide (GO) were layer-by-layer self-assembled onto flat PA reverse osmosis membrane surfaces by hydrogen bonding and physical absorption to address this challenge. Contact angle testing proved that the membrane surface hydrophilicity was improved with the increase of bilayers. The modified PA membrane with bilayer number
