Abstract
Commercial few‐layer graphite platelets were characterized by atomic force microscopy (AFM). Successive oxidation of the graphite platelets was carried out at 450–550 °C in air, and AFM measurements were performed after each oxidation step. The measurements showed that the applied thermal oxidation reduced the dimensions of the platelets. We have also observed the spontaneous assembly of the few‐layers thick platelets into a macroscopic, free‐standing film. Portions of this free‐standing graphite film were investigated by AFM and scanning tunneling microscopy (STM). (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
