DELAMINATION OF GRAPHITE BY ELECTROCHEMICAL INTERCALATION

A simple technique of electrochemical intercalation had been established to delaminate the graphite layers. The graphite sticks were set as electrodes in electrolyzer and electrotolyzed for about 24 h. The resulting product, nano grade powder, which dispersed homogeneously in water medium, were found in the form of thin lamina, with the size of 200 nm and the thickness of 2 nm~10 nm. FTIR revealed that the nanographite has been partly oxidized, while it was still conductive.
