Sodium ions will expand the spacing between graphene oxide layers because of the limiting effect, and thus the ordered structure of layer-by-layer membranes via GO disappeared after long running in the sodium ions. GO-OCNTs-LbL membrane was prepared by graphene oxide (GO) and oxidized carbon nanotubes (OCNTs) with 5 bilayers on a polyethersulfone membrane. Insert of OCNTs in the GO interlayer for GO-OCNTs-LbL membrane restricts the expansion of GO. Performance of FO membranes can be investigated by NaCl, MgCl2, Na2SO4, and sucrose as draw solutions and deionized water as feed solution. GO-OCNTs-LbL membrane has a higher water flux than GO-LbL membrane for NaCl, MgCl2, Na2SO4 and sucrose as DS. Solute flux of GO-OCNTs-LbL membrane for NaCl decreased by 70.2% than that of GO-LbL membrane. Therefore, GO-OCNTs-LbL membrane exhibit better rejection performance for NaCl than GO-LbL membrane.
