This work details the effect of varying the ratio of concentrations of oxidant-to-monomer, in the process of synthesizing Polyaniline (PANI) in emeraldine salt (oxidation state) form for pseudo capacitor application. The formation of emeraldine salt is confirmed by analytical characterizations such as Fourier Transform Infrared spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS) and Raman analysis techniques. The UV/Vis spectroscopic (UV) technique was employed to elucidate the optical band gap of variants. Both DC and AC measurements have shown a maximum total conductivity of 1.296 × 10³ S cm⁻¹. The cyclic voltammetry (CV) of variants exhibit reversible redox reactions due to back and forth transitions between emeraldine and pernigraniline oxidation states and high diffusion of ions in the fabricated polyaniline thin films. The electrochemical impedance spectroscopy has shown their low solution resistances and charge transfer resistances behaving like a near ideal capacitor and the specific capacitances of CER variants have been calculated by performing constant current discharge cell test showing a maximum specific capacitance of 30.2 Fg⁻¹. The variants also exhibit better coulombic efficiencies.

这项工作详细介绍了在合成用于伪电容器的翡翠盐（氧化态）形式的聚苯胺（PANI）的过程中，改变氧化剂与单体的浓度比的影响。通过诸如傅立叶变换红外光谱（FTIR），X射线光电子能谱（XPS）和拉曼分析技术之类的分析特征可以确认翡翠盐的形成。UV / Vis光谱（UV）技术用于阐明变体的光学带隙。直流和交流测量均显示最大总电导率为1.296×10 ³  S cm ^-1。变体的循环伏安法（CV）表现出可逆的氧化还原反应，这归因于翡翠和邻肾上腺素氧化态之间的来回转变以及所制备的聚苯胺薄膜中离子的高度扩散。电化学阻抗谱已显示出它们的低溶液电阻和电荷转移电阻表现为接近理想电容器，并且通过执行恒定电流放电室测试显示出CER变体的比电容，显示出30.2 Fg ^-1的最大比电容。这些变体还表现出更好的库仑效率。
