Abstract: Using the hydrogen-bonding interaction between graphene oxide(GO) and sulfonated polyethersulfone (SPES), we constructed the multilayer structure of GO and SPES on the polyester fiber mats via layer-by-layer self-assembly. In each self-assembled layer, sulfonic acid groups are arranged along the axis of fiber, which provides the long-range proton transmission channels, promoting the rapidly proton conduction. The performances of the composite membranes based on SPES and multilayer assembled polyester fiber mats were studied. The results show that the proton conductivity of composite membranes increases with the increasing assembly layers. At the same time, the mechanical properties and methanol-resistance of the composite membranes were obviously improved.
