摘要

process for the production of nanometer graphene platelets, nanometer graphene platelets, and thermoplastic polymer based compositions. a process for the production of nanometric graphene platelets, which comprises: a) bringing a graphite material into contact with molecular or atomic oxygen and obtaining a precursor consisting of graphite material functionalized with oxygen groups (fog) distinguished for a carbon / oxygen molar ratio higher than 8: 1, b) subsequently (chemically or physically) reduce said fog precursor by obtaining nanometer graphene platelets distinguished by a carbon / oxygen molar ratio greater than 20: 1.
