| Abstract: |
| This study reports the electrochemical synthesis of nanocomposite thin films composed of polyaniline (PANI) and copper oxide (CuO) deposited on Indium Tin Oxide (ITO)-coated glass substrates. The films were prepared via in-situ electropolymerization of aniline in the presence of CuO nanoparticles, followed by detailed structural, morphological, and electrochemical characterization. Scanning Electron Microscopy (SEM) revealed a uniform nanofibrillar morphology of PANI decorated with well-dispersed CuO nanoparticles. Electrochemical impedance spectroscopy demonstrated a dramatic reduction in charge-transfer resistance, with the ITO/PANI-CuO electrode achieving ~80 Ω·cm2 compared to ~3 000 Ω·cm2 for ITO/PANI and ~1 000 Ω·cm2 for ITO/CuO. Cyclic voltammetry confirmed the superior pseudocapacitive behavior of the hybrid electrode, with an areal capacitance of ~0.548 F/cm2, representing an enhancement of over two orders of magnitude relative to pristine PANI (~0.004 27 F/cm2). These findings highlight the strong synergistic effect between PANI and CuO, confirming the potential of the nanocomposite films as high-performance electrodes for supercapacitor applications. |
