Polypyrrole nanostructures formed by electrochemical method on graphite impregnated with paraffin

Polypyrrole nanostructures were prepared electrochemically by template-free method on graphite impregnated with paraffin. The experimental parameters, such as testing temperature, polymerization potential, doped ions and the status of the electrode surface have significant effect on the morphology of the formed polypyrrole. Under various experimental conditions, fibrillar, taper and cauliflower polypyrrole can be obtained. By controlling the active sites, the polypyrrole nuclei will grow in one-dimensional pattern, and thus polypyrrole nanowires were obtained. The method should be useful for preparation other materials nanowires.
