摘要
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.
