Various weight percentages of the GNP were added to the (1:1) molar ratio solution of aniline and pyrrole so as to generate the GNP-PANI-PPy nanocomposites. The prepared nanocomposites were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The characterizations conformed the formation of homogeneous composite having GNP-embedded in to the PANI-PPy hybrid polymer matrix. The electrochemical activity of the nanocomposite was examined in three electrodes and two electrode configurations. It was found that the cyclic voltammetry and galvanostatic charge-discharge studies revealed the excellent redox characteristics of the generated hybrid nanocomposites with high specific capacitance as high as 195 F g-1. The specific capacitance was found to be strongly influenced by the GNP amount. The symmetric device consisting of (GNP-PANI-PPy|Electrolyte|GNP-PANI-PPy) was constructed and its energy storage performances were evaluated and presented. � 2021 Elsevier Ltd. All rights reserved.
