Abstract Polyaniline (PANI) is one of the important materials in conducting polymers (CPs) for significant applications in devices due to its unique properties such as high electrical conductivity, flexibility, and economical price. In this work, novel and eco-friendly green synthesis of polyaniline Nanorod (PANI-NR) were developed by solar irradiation approach in acidic medium without the aid of any surfactant and template. As characterized by morphology studies, the average diameter of PANI-NR is approximately 200–250 nm and length is 2–2.5 µm. The elemental analysis and structural geometry of PANI-NR are examined through EDX, Mapping, and XRD studies. The electrochemical properties were investigated using CV, GCD, and EIS techniques. The electrochemical performance of Cyclic voltammetry analysis shows the redox peaks which confirms the PANI-NR has excellent electrical conductivity. A specific capacitance of 25 F/g at 10 mV/s scan rate by CV studies and 106 F/g at 1 A/g current density by GCD studies is observed for One-Dimensional (1D) PANI-NR as an electrode material for supercapacitor. Also, it shows remarkable cyclic retention and stability. These results indicate that PANI-NR is expected to have better electrochemical performance in energy storage applications.

用于高效电化学超级电容器的新型一维聚苯胺纳米棒：一种简便且绿色的方法

摘要 聚苯胺 (PANI) 是导电聚合物 (CPs) 的重要材料之一，因其具有高导电性、柔韧性和经济价格等独特特性，在器件中具有重要应用。在这项工作中，在没有任何表面活性剂和模板的帮助下，在酸性介质中通过太阳照射方法开发了聚苯胺纳米棒（PANI-NR）的新型环保绿色合成方法。根据形态学研究的特点，PANI-NR 的平均直径约为 200–250 nm，长度为 2–2.5 µm。通过 EDX、映射和 XRD 研究检查 PANI-NR 的元素分析和结构几何。使用 CV、GCD 和 EIS 技术研究了电化学性质。循环伏安分析的电化学性能显示了氧化还原峰，这证实了 PANI-NR 具有优异的导电性。对于作为电极材料的一维 (1D) PANI-NR，通过 CV 研究观察到在 10 mV/s 扫描速率下的比电容和通过 GCD 研究在 1 A/g 电流密度下观察到的比电容为 106 F/g超级电容器。此外，它还表现出显着的循环保持力和稳定性。这些结果表明，PANI-NR 有望在储能应用中具有更好的电化学性能。
