In this study, aniline-based monomer, N,N′-(propane-1,3-diyl)bis(2-aminobenzamide), (PAB), was synthesized and characterized by proton nuclear magnetic resonance (1H-NMR), carbon-13 nuclear magnetic resonance (13C-NMR), and Fourier transform infrared spectroscopy. The electropolymerization of the monomer was performed on glassy carbon electrode by cyclic voltammetry (CV). The effects of solvent, dopant, scan number, and scan rate on the electropolymerization and properties of the poly(PAB) films were investigated. The modified electrode was also characterized by Fourier transform infrared-attenuated total reflection spectroscopy and scanning electron microscopy–energy-dispersive X-ray analysis. The capacitive properties of the poly(PAB) films were firstly tested by electrochemical impedance spectroscopy. The highest specific capacitances (C sp) of poly(PAB) films were obtained as C sp = 6.22 mF cm−2 in 0.1 M lithium perchlorate/acetonitrile (ACN) for [PAB]0 = 20 mmol dm−3 and C sp = 16.9 mF cm−2 in 1 mol dm−3 sulfuric acid for [PAB]0 = 5 mmol dm−3 at the scan rate of 5 mV s−1 from CV measurements. This study is novel because it was the first study on capacitance performances of poly(PAB) films in the literature.

N,N'-(propane-1,3-diyl)bis(2-aminobenzamide) 的电聚合、表征和电容器研究

在本研究中，合成了苯胺基单体 N,N'-(propane-1,3-diyl)bis(2-aminobenzamide), (PAB) 并通过质子核磁共振 (1H-NMR)、碳-13核磁共振（13C-NMR）和傅里叶变换红外光谱。通过循环伏安法（CV）在玻碳电极上进行单体的电聚合。研究了溶剂、掺杂剂、扫描次数和扫描速率对聚 (PAB) 膜的电聚合和性能的影响。改性电极还通过傅里叶变换红外衰减全反射光谱和扫描电子显微镜 - 能量色散 X 射线分析进行表征。聚（PAB）薄膜的电容特性首先通过电化学阻抗谱测试。聚 (PAB) 薄膜的最高比电容 (C sp) 是在 0.1 M 高氯酸锂/乙腈 (ACN) 中获得的 C sp = 6.22 mF cm-2，[PAB]0 = 20 mmol dm-3 和 C sp = 16.9 mF cm-2 在 1 mol dm-3 硫酸中，[PAB]0 = 5 mmol dm-3，扫描速率为 5 mV s-1，来自 CV 测量。这项研究是新颖的，因为它是文献中关于聚（PAB）薄膜电容性能的第一项研究。
