Graphene / polyaniline nanocomposite was successfully produced by using aniline monomer react with expendable Graphite in the assistance of supercritical carbon dioxide (SC CO<sub>2</sub>). The graphite was intercalated by the aniline monomer and exfoliated during the aniline polymerization. The resulting graphene / polyaniline nanocomposite was fully characterized by transmission electron microscopy (TEM), Atomic force microscope (AFM), Fourier transform infrared spectroscopy (FTIR), Raman spectra, Thermo Gravimetric Analyze (TGA) and fluorescence spectrometer. We had demonstrated a single-step process to achieve the aniline intercalation and polymerization to make the Graphene /Polyaniline composite. The polyaniline was firmly attached at on the surface of graphene to form a uniform “comb” network structure, which had the benefit to leverage the functional performance from polyaniline and nano features from Graphene structure. The functionalized Graphene / polyaniline nanocomposite would have potential applications in surpercapacitor, transparent electrodes and catalysis, and nano devices.
