摘要：

A new method for electrochemically in situ conductivity measurements based on a reusable glassy carbon disc carbon fibre array double electrode is described. Using this technique and cyclic voltammetry, we have investigated the effects of the doping anion and solvent on the electrochemical properties of polypyrrole film. The electroactivity and potential dependent conductivity of polypyrrole film are strongly affected by solvent and the doping anion's solubility in the solvent, and also by the history of electrochemical treatments in different electrolyte solutions. It is very interesting that NO3-doped polypyrrole can completely keep its conducting state (doped state) at a reasonably negative potential (eg -0.8 V vs. sce) in acetonitrile solutions.
