▎ 摘  要

NOVELTY - Graphene oxide is prepared by oxidizing graphite by a strong oxidant; stripping the graphite oxide by ultrasonic wave; regulating pH value of the graphite oxide; deionizing the graphite oxide sol; washing and filtering the obtained monoatomic lamellar graphene oxide; and drying and ball-milling the product to obtain graphene oxide in thickness of single or multiple atoms. USE - Method for the preparation of graphene oxide (claimed). ADVANTAGE - The method is simple, efficient, and high-energy. DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of the method for preparation of graphene oxide (claimed).
