Beschreibung
Zusammenfassung:	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 8:1 b) subsequently, reducing (chemically or physically) said FOG precursor obtaining nano-scaled graphene platelets characterized by a carbon/oxygen molar ratio higher than 20:1.
