摘要：
Ultra thin graphene oxide (GO)/polyvinyl alcohol and graphene-polyvinyl alcohol/gelatin composite films were fabricated by electrostatic layer-by-layer assembly and spinning coating methods. The assembling and coating process were traced with UV-visible absorption spectroscopy and the morphology of the formed ultra thin films was observed under scanning electron microscopy. The results show that the adsorption value of the GO based composite films linearly increased as the number of layers increased. The ultra thin graphene oxide/polyvinyl alcohol and graphene-polyvinyl alcohol/gelatin composite films have layered structure with high tensile strength because of the incorporation of GO. These strong ultra thin films have potential applications in coating, sensor and electrochemical devices.
