New method to prepare graphite nanocomposites

The carbon nanosheets are obtained as a by-product during preparation of fullerene and carbon nanotubes, many methods have been developed exclusively to prepare graphite nanosheets, which include micromechanical cleavage, chemical vapor deposition, and chemical routes through graphite intercalation compounds. The synthesis of dispersing graphene nanosheets in a uniformly polymer matrix is a difficult process, but the uniform dispersion of GO nanosheets in polymer matrices is relatively more successful. The chemical reduction of GO sheets in water always results in their irreversible coagulation and restacking, making the sheets difficult to redisperse. The reduction of GO is also confirmed by elemental analysis, as the C/O ratio have been used as a conventional measure of the oxidation degree of graphitic materials. The TEM micrograph gives the cross-sections of the graphite nanosheets, which are 1-3 nm thick and finely dispersed in the polysulfide matrix.
