Abstract

Polypyrrole/PEOLiClO4 junctions were prepared in situ by the electrochemical polymerization of pyrrole in the polymer electrolyte PEOLiClO4. The junction prepared in situ by the potential sweep method exhibited rectifying behavior in the current-voltage curves. The capacitance-voltage properties of the junction showed an energy barrier at the interface between polypyrrole and PEOLiClO4. On the contrary, polypyrrole/PEOLiClO4 junctions prepared in situ by galvanostatic and potentiostatic methods did not show rectifying behavior. These results are explained on the basis of the properties of the interface between p-type polypyrrole and the polymer electrolyte.
