CLASSIFICATION METHOD OF GRAPHENE OXIDE AND GRAPHENE OXIDE CLASSIFICATED BY THE SAME

摘要

The present invention relates to a method for classifying graphene oxide and graphene oxide classified by the method, and a method for classifying graphene oxide according to an aspect of the present invention includes preparing two or more types of graphene oxide having different sizes. step; Dispersing the graphene oxide in an organic solvent/water mixture; And separating the precipitate and the supernatant liquid dispersed in the organic solvent/water mixture.
