CHROMIUM DOPED POLYANILINE/MWCNTS NANOCOMPOSITE FOR SUPERCAPACITOR ELECTRODE MATERIALS

In this study we have prepared Cr-doped polyaniline/MWCNTs [Cr-PANI-CNT] nanocomposite by simple in-situ polymerization method where ammonium persulphate used as oxidant in HCl medium. The probable interaction between the Cr with both MWCNTs and PANI is investigated by Fourier transform infrared spectroscopy (FTIR) analysis. The morphological analysis of the nanocomposite was studied by FESEM and TEM analysis. The electrochemical performance of the nanocomposite was characterized by three electrode method. The nanocomposite showed the highest specific capacitance of 328 F/g at 10 mV/s scan rate.
