Abstract: M onovalent-selective ion-exchange membranes were fabricated by adding graphene oxide (GO) to polyacrylic acid (PAA) and alternately deposited on the surface of cation-exchange membrane with polyetherimide (PEI) through layer-by-layer self-assembly (LBL).The result indicated that the composite membranes terminated with PEI had higher separation efficiency. GO was deposited onto the membrane surface evenly and continuously with the assembly of polyelectrolyte. The surface resistance of the composite membranes increased with the assembled number of bilayers. Moreover, the addition of GO is beneficial to reduce the membrane resistance compared to the multilayer membranes without GO. The composite membranes exhibited improved separation efficiency with the assembled bilayers. Besides, the separation efficiency increased firstly and then decreased with the GO concentration and showed the highest selectivity with GO concentration of 0.5 g/L.
