Coal-based Carbon Nanofibers Prepared by Electrospinning for Supercapacitor†
摘要
Abstract
Coalbased carbon nanofibers with uniform diameters were prepared by means of electrospinning with oxidized coal, polyacrylonitrile(PAN) and N,Ndimethylformamide(DMF). Coalbased supercapacitor electrodes were further obtained by carbonization and activation. The phase and morphology of precursor and final product were characterized via energy dispersive spectroscopy ( EDS ) , BrunauerEmmettTeller ( BET ) adsorptiondesorption isotherm, scanning electron microscopy( SEM) , Fourier transform infrared spectroscopy ( FTIR) and thermogravimetric analysis( TGA) . The results indicated that the solubility of raw coal in organic solvents can be enhanced after oxidizing treatment with potassium permanganate because of the disconnection of alkyl chains in macromolecules and the increase of oxygen containing groups. Electrochemical testing of the coalbased electrode showed a specific capacitance of 259. 7 F/g at a current density of 1 A/g in threeelec trode system, and a capacity retention of 99. 2% after 1000 cycles at a current density of 5 A/g.关键词
