摘要：

Polypyrrole (PPy) solution has been prepared by dissolving PPy powder in m-cresol after doping with sodium dodecylbenzenesulfonate, and free-standing film of PPy has been cast from the solution. The PPy prepared in this way has very shiny smooth surfaces and contains approximately 13% of the solvent. The activation energy of electrical conduction was found to be 0.14 eV. It has been concluded that the solvent, i.e. m-cresol, plays an important role in electrical conduction as well as the enhancement of electrical conductivity during annealing at around 120 degrees C. The decrease in electrical conductivity as the PPy film is heated above 140 degrees C is due to the loss of solvent.
