Technological Characteristics of the Processes of Carbon Nanostructure Production by the Methods of Plasma-Arc and Gas-Pyrolytic Deposition

摘要

The techniques of pyrolytic vapor deposition from acetylene and plasma-arc vacuum deposition of graphite are used to prepare carbon nanotubes (CNTs). Graphite electrodes for plasma-arc deposition are premodified with transition metals by electrochemical deposition from aqueous solutions of their salts. It is shown by SEM and AFM that the structure and morphology of the surface of CNT samples depends on the synthesis technique.
