DETAILED DESCRIPTION - Oxidized graphene organic solution preparation involves determining target solution of oxidized graphene organic solution according to actual needs, and then determining target concentration of the oxidized graphene organic solution. The concentration and volume of the target oxidized graphene organic solution are calculated and assumed. The calculated aqueous graphene solution is added in organic solvent in a container with agitator to form mixed liquid. The obtained mixed liquid is transferred into distillation or fractionation equipment under vacuum conditions with stirring for 10-30 minutes at a rotational speed of 50-1000 revolutions per minute (rpm). The distillation or fractionation temperature is adjusted between the azeotropic point of the water and the organic solvent and the boiling point of the organic solvent under the vacuum conditions. The distillation or fractionation is started, where the evaporated water is condensed by using condensing medium. The organic solvent is added into organic solution of the oxidized graphene in the distillation or fractionation bottle. The organic solution is sonicated for 10-1200 seconds to obtain total solution of graphene oxide. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic scanning electron microscopic photograph of the oxidized graphene organic solution.
