The PANi/GO thin film was reduced electrochemically with different potential windows, scan rate and number of cycles which was acquired using layer-by-layer (LBL) assembly method. The resultant electrodes displayed various specific capacitances after pre-reduction with different conditions.The influence of the electrochemical reduction was investigated by Raman spectroscopy and X-ray photoelectron spectroscopy for capacitance performance. The optimum conditions were explored for supercapacitor application and an elevated specific capacitance 2619 F cm<sup>-3</sup> (areal capacitance 18.38 mF cm<sup>-2</sup>) at 1 mV s<sup>-1</sup> obtaining the film reduced with applied potential of -0.87 to -0.5 V. This study could introduce the new possibilities for the improvement of the electrochemical reduction effects to the composite materials for high-performance supercapacitors.</p> ER -
