利用交流电化学热方法测定了Ｂｒ－／Ｂｒ２和Ｐｂ／Ｐｂ２＋电极的电极反应熵变．在动电位情况下利用该方法研究了聚吡咯电极反应．结果表明经碱溶液处理后聚吡咯电极的电化学活性明显下降，但从交流电化学热性质看，它还部分保留了原先聚吡咯电极的电极反应特性．
The electrode reaction entropy change of Br- / Br2 and Pb / Pb2 + electrodes was measured by AC electrochemical thermal method. The method was used to study the polypyrrole electrode reaction at the potentiodynamic condition. The results showed that the electrochemical activity of polypyrrole electrode decreased obviously after treated with alkali solution. However, it also partially retained the electrode reaction characteristics of polypyrrole electrode.
