Abstract:
The process comprises the following steps: mixing lamellar graphite, containing an intercalating material, with NaNO3 and adding the mixture to a solution of H2SO4 (98%) under continuous stirring; cooling the mixture in an ice bath; adding, very slowly, from 2% to 10% of KMnO4, during a period of time up to 1 h, maintaining the stirring; removing the mixture from the ice bath, heating it and maintaining it under stirring, until the formation of graphene oxide; diluting the mixture in deionized water until the volume of the solution has increased at least 30% and the temperature has not exceeded about 60° C.; leaving the mixture to stand for completing the reaction; heating the mixture between 95° C. and 100° C. and keeping it under high stirring. Adding deionized water and hydrogen peroxide to the mixture, for completion of the oxidation reaction; purifying the mixture by washing it with a solution of HCl and, then, with deionized water, for removing the acids: and filtering and drying the mixture for obtaining the graphene oxide in powder with a conversion degree higher than 90%.

Claim (Index 3):
The process, according to  claim 2 , characterized in that the intercalating polymer is selected among commercial polymers having oxygen in the structure thereof.
