[54] PROCESS FOR THE PREPARATION OF NANO-SCALED GRAPHENE PLATELETS WITH A HIGH DISPERSIBILITY IN LOW-POLARITY POLYMERIC MATRIXES AND RELATIVE POLYMERIC COMPOSITIONS
[57] Abstract: A process for the production of nano-scaled graphene platelets which comprises:a putting a graphite material in contact with molecular or atomic oxygen or a substance capable of releasing molecular or atomic oxygen, obtaining a precursor consisting of graphite material functionalized with oxygen groups FOG, characterized by a carbon/oxygen molar ratio higher than 8:1b subsequently, reducing chemically or physically said FOG precursor obtaining nano-scaled graphene platelets characterized by a carbon/oxygen molar ratio higher than 20:1
