When evaluated as supercapacitor electrodes，the charge transfer resistance decreased from 3.31 Ω （PANI/CFs） to 1.84 Ω （PANI/m-CFs）， and the areal specific capacitance reached 2 098mF/cm2 at 1mA/cm2 of current density. Furthermore， the cycling stability improved from 73.6% to 78.9% after modification.
