In Situ Observation and Selective Electrochemical Deposition of Polypyrrole by Scanning Tunneling Microscope

Abstract
Electrodeposition of polypyrrole and its selective deposition on a highly oriented pyrolytic garaphite asubstrate was observed in situ by means of scanning tunneling microscope (STM) in an electrochemical cell. The results indicated that the STM can be used to manipulate the electrodeposition of conducting polymers.
