A novel approach is used to synthesize graphite oxide (GO) coated with polyaniline (PANI) by in-situ emulsion polymerization. The dispersion behavior of exfoliated graphite oxide in aqueous solution under ultrasonic vibration is investigated by atomic force microscopy (AFM). Strong interactions owing to hydrogen bonds and electrostatic effects between PANI and GO surfaces are revealed by FT-IR and Raman spectra. Scanning electron microscopy (SEM) further confirms that GO is well-coated with PANI, and a uniform appearance is seen. The increased crystallinity of PANI/GO is characterized by X-ray diffraction (XRD). The product is also characterized by thermogravimetry(TG) and electrical conductivity.
