因有机酸掺杂可提高聚苯胺的导电性及其电化学性能而备受关注。分别以有机酸十二烷基苯磺酸（DBSA）、水杨酸（SA）与盐酸作为共掺杂剂,采用化学氧化聚合法制备聚苯胺（PANi）材料。采用傅里叶红外光谱仪（FTIR）与扫描电子显微镜（SEM）对聚苯胺样品进行微观结构与形貌表征,并通过循环伏安（CV）、恒电流充放电（GCD）及交流阻抗（EIS）测试分析其电化学性能。研究结果表明,与单一盐酸掺杂的聚苯胺相比,采用有机酸DBSA共掺杂合成聚苯胺对其分子链结构影响较大,电化学性能变差;而采用有机酸SA共掺杂合成的聚苯胺具有更好的电化学性能,在1 A/g电流密度下,比电容可达533.3 F/g,聚苯胺电极材料与电...

Polyaniline (PANi) with organic acid doping has attracted much attention due to superior conductivity and electrochemical performance. In this study,PANi samples were synthesized by oxidative polymerization using organic acids as co-dopants,such as dodecylbenzene sulfonic acid (DBSA),salicylic acid (SA) and inorganic acid (hydrochloric acid). The microstructure and morphology of polyaniline samples were characterized by Fourier transform infrared spectrometer (FTIR) and scanning electron microscope (SEM). Besides,their electrochemical performances were investigated by cyclic voltammetry (CV),g...
