摘要：

Oxidation chronoamperograms of highly compacted polypyrrole films were performed in propylene carbonate solutions containing different electrolytes (LiF, LiCl, LiBr and LiI), allowing the study of the effect of the counterion size on the rate of electrochemical switching controlled by conformational relaxation processes.
