We have used atomic force microscopy (AFM) to investigate the surface morphology of poly(N-methylpyrrole) after electropolymerization on indium tin oxide and highly oriented pyrolytic graphite (HOPG) surfaces. We have found that the polymer surface became rougher with higher current density or lower solution temperature. In situ observations of the initial stages of electropolymerization revealed that an extremely weak adhesion exists between the polymer and HOPG. As a result, the AFM tip-sample interaction could easily move the polymer, and we have proposed that this can be used for patterning surfaces.
