摘要：

用聚有机二硫化物与聚苯质共混，是提高聚苯胺的电化学性能的有效方法之一．以二硫二磺酸为掺杂剂掺杂的聚苯胺, 可明显地改善聚苯胺的电化学活性，使聚苯胶与掺杂剂中的－S－S－在相同的区域内共同参与氧化还原反应，提高了聚苯胺的电容量和充放电循环性．

Abstract:

One method to improve efficiently polyaniline's electrochemical properties is the comixing of polyaniline with disulfide disulfonic acid. When doped with disulfidedisulfonic acid, polyaniline's electrochemical activity is greatly improved. The bondage-S-S-of the dopant coparticipates oxidation-reduction reaction with polyaniline in the same area, thus polyaniline's capacity and charge-discharge cyclibility are improved.
