FO is prominent membrane technology for desalination due to no hydraulic pressure requirement and low fouling propensity compared to RO. TFC membrane was widely used due to excellent perm-selectivity and chemical resistance. TFC membrane consists of dense and support layer. Academic efforts focused on advance TFC membranes characteristics and performances. This work attempts to fabricate TFC FO membrane with highly permeable ultra-thin intermediate layer on the support layer using polydopamine and graphene oxide. Role of the intermediate layer on performances was demonstrated via characterization and FO operation.
