The supercapacitor performance of the nanocomposites was studied by Fourier transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The electrochemical properties of electrodes were also investigated by cyclic voltammetry (CV), galvanostatic charge–discharge and electrochemical impedance spectroscopy (EIS) techniques in 0.5 M Na2SO4. The specific capacitance of 321.47 F. g-1, 277.77 F. g-1 and 80 F. g-1 obtained for PANI/MnO2-MWCNT, MnO2-MWCNT and MWCNT, respectively. The EIS results also showed that the capacitive behavior of MWCNT was improved by the addition of MnO2 and PANI. https://icc.journals.pnu.ac.ir/article_1754_00ec4d6c8f528c5762ce5206bb90f807.pdf
