It has been shown that laser can induce selective local electropolymerization of polypyrrole (PPY) and poly-o-phenylenediamine(POPD). The resonance Raman spectroscopic result indicates that the structure of the laser-induced PPY is nearly identical to that of the PPY formed under the normal condition of electropolymerization. It seems to be reasonable to assume that the laser induced thermal effect is most likely to influence the electropolymerization kinetics, as the temperature rise at the illuminated surface area results in considerable shift of the equilibrium potential. Electrochemical micro-patterns were achieved by laser-induced electropolymerization of PPY and POPD on Au and HOPG electrode. The diameter of points and the width of lines obtained are about 2~4 and 8 micrometers respectively.
