Thermally expanded graphite (TEG) is a vermicular-structured carbon material that can be prepared by heating expandable graphite compounds. Liquid phase exfoliation of TEG obtained from graphite nitrate cointercalation compounds (GNCCs) with organic substances allows obtaining dispersions of carbon nanoparticles, namely few-layer graphenes as well as small graphene structural fragments. This paper presents the results of complex investigations of structural features of triple GNCCs with acetic acid, formic acid, ethyl acetate and acetonitrile as well as TEGs on their base. X-Ray powder diffraction and scanning electron microscopy were used for studied GNCCs and TEGs characterization. GNCCs were used as a source for thermally expanded graphite which can be considered as perspective precursor for graphene and related structures. Morphology of the carbon nanoparticles formed from corresponded TEGs by liquid phase exfoliation in tert-butanol assisted with sonication is discussed. The most promising results were observed for the TEG sample obtained from a triple GNCC with acetic acid and acetonitrile. – (Springer Proceedings in Materials ; Vol. 41) .
