چکیده انگلیسی
A ternary nanocomposite consisting of polypyrrole (PPy), graphene oxide (GO) and multi-walled carbon nanotube (MWCNT) for supercapacitor was prepared via facile one step potentiostatic technique. Field emission scanning electron microscopy (FESEM) images displayed a randomly entangled nanostructure of MWCNT with rough wrinkle surface of GO incorporating with PPy granular structure represent the morphology of PPy/GO/MWCNT nanocomposite. The ternary nanocomposite was further justified its chemical composition by using Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. PPy/GO/MWCNT exhibited a high specific capacitance of 358.69â¯Fâ¯gâ1â¯at a scan rate of 100â¯mVâ¯sâ1 in 1â¯M Na2SO4, which is comparatively higher than both binary nanocomposites, PPy/MWCNT (207.52â¯Fâ¯gâ1) and PPy/GO (139.03â¯Fâ¯gâ1). The PPy/GO/MWCNT nanocomposite also possessed much longer charge-discharge time and excellent cycling stability (88.69%) with the specific energy of 40.45â¯Wh/kg and specific power of 441.24â¯W/kg. Therefore, PPy/GO/MWCNT nanocomposite is a potential electrode material for high-performance supercapacitor.
