摘要： The present invention relates to a partially oxidized graphene and a method for preparing the same. Since the partially oxidized graphene is prepared by subjecting the partially oxidized graphite to a high pressure homogenization, the exfoliation efficiency is excellent, the inherent characteristics of graphene are maintained even without using a reduction step after exfoliation, and the dispersibility thereof in organic solvents is excellent, and thus the invention can be applied to various fields.
