Abstract: Electrochemical scanning tunnelling microscope (ECSTM) has been used in situ to follow the progress of pyrrole electropolymerized on HOPG.ECSTMexperiments show that the initial state in the formation of films is polypyrrole chains on the electrode surface, and provide an evidence that the growth of polypyrrole films resembles that of metal film on HOPG.

Key words: Polypyrrole, ECSTM, Electropolymerized mechanism
