Abstract

Samples of polyaniline synthesized from aniline sulfate were electrochemically cycled in LiCl, LiClO₄, and lithium tetracyanoquinodimethane, with the electrolyte replacement. In all studied cases, the polyaniline is shown to retain its electrochemical activity upon the electrolyte and doping anion replacement. The electrochemical activity with the Cl^– and \({\text{ClO}}_{4}^{ - },\) dopants is reduced in the first cycles upon the electrolyte replacement; however, in the subsequent cycles the reduction decreased. When the electrode under testing has been returned to the native electrolyte, its electrochemical activity and electrochemical capacitance increased, recovering their initial values. When polyaniline has been doped with the tetracyanoquinodimethane anion, each next cycling series revealed an increase in its electrochemical activity, which manifests itself in the cyclic voltammogram area, as well as increase in the electrochemical capacitance from one cycling series to the next one.

掺杂阴离子置换对聚苯胺电化学行为的影响

抽象的

由硫酸苯胺合成的聚苯胺样品在LiCl，LiClO ₄和四氰基喹二甲烷锂中进行电化学循环，并替换电解质。在所有研究的情况下，聚苯胺均显示出在电解质和掺杂阴离子替代物上保持其电化学活性。与CL中的电化学活性^-和\（{\文本{CLO}} _ {4} ^ { - }，\）在更换电解液后的第一个循环中减少掺杂剂；但是，在随后的循环中，减少量减少了。当被测电极恢复为天然电解质时，其电化学活性和电化学电容增加，恢复其初始值。当聚苯胺已掺入四氰基喹二甲烷阴离子时，每个下一个循环系列均显示其电化学活性增加，这在循环伏安图区域中表现出来，并且从一个循环系列到下一个循环系列的电化学电容也增加。
