摘要：

Graphite platelets of 1-5 mu m in diameter consisting of a few graphenes were generated from commercially available exfoliated graphite by ultrasonic treatment in benzene (1 mg material in 20 ml solvent) for 3 h. Droplets from the suspension were dispersed on silicon wafer. The graphite platelets were characterized by atomic force microscopy (AFM). Successive oxidation of the sample was carried out at 450-550 degrees C in air. AFM measurements showed that the thermal oxidation removed 2-3 graphenes from the platelets and it left behind single graphene layers. (C) 2007 Published by Elsevier Ltd.
