Electrochemical Synthesis of Polyaniline Nanobelts with Predominant Electrochemical Performances

Polyartiline (PANI) as one of most promising conducting polymers has attracted much attention because of its low cost, superior electrochemical performance, distinguishable electrical properties, mechanical flexibility, and relative ease of processing. In this article, we explored a novel route to prepare PANI nanobelts directly onto conducting substrates by electrodeposition, which represents a facile synthetic method for the Synthesis of high quality samples with excellent electrical contact to a substrate, which is critical for further supercapacitor testing. I-lie products were characterized by scanning electron microscopy (SEM), powder X-ray diffraction analysis (XRD), and Fourier transform infrared (FTIR) analysis. These prepared PAN[ nanobelts were found to haven large Surface area, which promotes remarkable enhancement in the performance of supercapacitors. The PANT electrodes composed of nanobelts showed a high specific capacitance (SC) value of 873 Fg(1-) at 10 mVS(-1) and high stability over 1000 cycles. The results of electrochemical measurements show that these PANI nanobells have a potential application as high-performance supercapacitor electrode material.
