Polyaniline/clay Nanocomposites: Preparation, Characterization and Electrochemical Properties. Issue 1 (17th February 2015) - Vijayakumar, B
Abstract: Preparation of polyaniline (PAni)/clay nanocomposites by reacting aniline with ammonium persulphate in presence of clay at 0-5 °C for 12 h. The composites were characterized by X-ray diffraction, infrared spectroscopy, UV-vis diffuse reflectance spectroscopy and thermogravimetric analysis for their physicochemical properties. Morphology was studied by scanning electron microscopy. The electrochemical studies of PAni/clay nanocomposites were carried out using cyclic voltammetry in 0.5 M H2 SO4 aqueous electrolyte. The PAni/clay nanocomposites showed specific capacitances of 415-455 Fg −1 at a scan rate of 10 mVs −1 .
