Polyaniline-Graphene (Pan-GF) nanopaper composite material was successfully synthesized by in-situ polymerization of aniline intercalating into graphene oxide with ammonium peroxydisulfate (APS) in the presence of inorganic acid. After reducing GO/PANI, rGO/PANI nano composite material was got. We prepared nanopaper using GO/PANI and rGO/PANI, which has high conductivity and strong tensile strength. The reaction mechanism along with the corresponding oxidation states and doping levels were proposed and characterized by various equipments, such as ESR, UV/vis, FTIR, CV, SEM, TEM, XRD, TGA/DSC, Roman, etc. It was found that we can use one-step process to achieve the aniline intercalation and polymerization to make the Pan-GF nano composite. The nano featured polyaniline fabric material was attached on the surface of graphene to form a uniform network structure, which showed significant reducing the filler loading for polymer blending system. And based on the phenomenon, we make a preparation of the nano composite material nanopaper. Various potential industrial applications will be presented in terms of surpecapacitor, polymeric nano composite, extrusion, injection molding, EMI shielding, anti-corrosion, and electric heaters, etc.
