NOVEL POLYPYRROLE MICROSTRUCTURES GENERATED BY DIRECT ELECTROCHEMICAL OXIDATION OF PYRROLE ON p-TYPE SILICON SUBSTRATE

Polypyrrole microstructrues with morphology like bowls, cups, goblets and bottles have been electrochemically generated by direct oxidation of pyrrole on p-silicon substrate in the aqueous solution of camphorsulfonic acid. The wellordered microstructures can stand upright on the working electrode surface and their morphological features can be easily controlled by changing the electrochemical polymerization conditions. The growing process of microstructures was studied by scanning electron microscopy. The microstructures made ofpolypyrrole films in doped state were characterized by Raman and Infrared spectra.
