Preparation of GrapheneNanosheets/CarbonNanotube/Pt/Polyaniline Nanocomposite with high specific capacitance as Electrode Material forSupercapacitors

GrapheneNanosheets/Carbon Nanotube/Pt/Polyaniline Nanocomposite (GNS/CNT/Pt/PANI) is synthesized via in situ polymerization. The PANI nanofibers was homogeneously coating on thesurface of GNS greatly improve the charge transfer reaction. CNTs as conductive wires interconnected among GNS/PANI particles and also Pt nanoparticles as an extender surface area. Electrochemical properties were characterized by cyclicvoltammetry (CV), electrochemicalimpedance spectroscopy (EIS) and galvanostatic charge/discharge. This analysis showed that theGNS/CNT/Pt/PANI composites exhibit remarkable specific capacitance than the pure individual components.
