Abstract This work studied the effect of self-doped polyaniline (SPANI)-assembled carbon nanoparticles (CNPs) on a supercapacitor. SPANI was in situ polymerised and assembled on CBs by mixing the monomers o-aminobenzenesulphonic acid (SAN) and aniline (AN) with an initiator and CNPs. SAN acted as a self-doped monomer and a surfactant. SPANI-modified CNPs used as an electrode material would improve the performance of CB-based supercapacitor. Variation of the molar ratio of AN/SAN altered the performance of the SPANI–CNP-based supercapacitor. Cyclic voltammetry, galvanostatic charge–discharge, and electrochemical impedance spectroscopy were employed to investigate the properties of the supercapacitors. The SPANI–CNP-based supercapacitor attained optimal performance at an AN/SAN ratio of 1.0, exhibiting a specific capacitance of 342 Fg− 1 at a charging current density of 0.5 Ag− 1 in a symmetric cell.

使用分子自组装聚苯胺在碳纳米颗粒上增强超级电容器的性能

摘要 这项工作研究了自掺杂聚苯胺 (SPANI) 组装的碳纳米粒子 (CNP) 对超级电容器的影响。通过将单体邻氨基苯磺酸 (SAN) 和苯胺 (AN) 与引发剂和 CNP 混合，SPANI 被原位聚合并组装在 CB 上。SAN充当自掺杂单体和表面活性剂。用作电极材料的 SPANI 修饰的 CNP 将提高基于 CB 的超级电容器的性能。AN/SAN 摩尔比的变化改变了基于 SPANI-CNP 的超级电容器的性能。采用循环伏安法、恒电流充放电和电化学阻抗谱来研究超级电容器的性能。基于 SPANI-CNP 的超级电容器在 AN/SAN 比率为 1.0 时获得最佳性能，
