Method for manufacturing graphene oxide and the graphene oxide manufactured by the same

The present invention relates to a manufacturing of graphenes, and especially to a method for manufacturing graphene oxides, and the graphene oxides thereof. The present invention as described comprises: a step of preparing an oxidation-graphite dispersion; a step of generating eddy on the oxidation-graphite dispersion and desquamating the oxidation-graphite; and a step of obtaining oxidation-graphite produced by the desquamated oxidation-graphite.
