METHODS FOR PRODUCING GRAPHENE WITH TUNABLE PROPERTIES BY A MULTI-STEP THERMAL REDUCTION PROCESS
A process for the preparation of graphene includes the steps of a) providing flash thermal treatment of a graphite oxide at a temperature up to 700° C. sufficient to produce exfoliation and under inert atmosphere and b) cooling the material obtained in the previous step below 90° C. The method furth...

| description | A process for the preparation of graphene includes the steps of a) providing flash thermal treatment of a graphite oxide at a temperature up to 700° C. sufficient to produce exfoliation and under inert atmosphere and b) cooling the material obtained in the previous step below 90° C. The method further includes the step of c) heating the material resulting from the previous step under inert atmosphere at a temperature which is higher than the temperature of step a), wherein the heating rate is between 1 and 15° C./min. The graphenes obtained from the process exhibit excellent physico-chemical properties. |
