| 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 ~3000 Ω·cm2 for ITO/PANI and ~1000 Ω·cm2 for ITO/CuO. Cyclic voltammetry confirmed the superior pseudocapacitive behavior of the hybrid electrode, with an areal capacitance of ~0.548 F·cm?2, representing an enhancement of over two orders of magnitude relative to pristine PANI (~0.00427 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. |

| 本研究旨在探讨由聚苯胺（PANI）和氧化铜（CuO）组成的纳米复合薄膜的电化学合成方法，该薄膜沉积于涂有氧化铟锡（ITO）的导电玻璃基底上。该方法通过在酸性电解质介质（H2SO4）中进行电化学聚合，实现在PANI薄膜中原位引入CuO纳米粒子。为了确保CuO纳米粒子在PANI基体中的有效分散，研究中严格控制了关键的合成参数，如施加电位、沉积时间以及单体浓度。利用多种表征技术对所制备复合材料的结构与形貌特性进行了分析，包括扫描电子显微镜（SEM）用于观察表面形貌，紫外-可见光（UV-Vis）光谱用于确认化学成分。此外，还通过电化学阻抗和电容分析，评估了该薄膜作为超级电容器电极的性能。结果表明，与纯PANI薄膜相比，CuO掺杂显著增强了PANI/CuO复合薄膜的电化学响应，循环伏安图的面积明显增加。上述研究结果表明，该纳米复合材料的有序结构在高性能超级电容器应用方面具有良好的发展前景。 |
