NOVELTY - Preparation of graphene oxide, involves: mixing graphite raw material and oxidant by mechanical action and oxidation reaction. USE - For preparation of graphene oxide (claimed). ADVANTAGE - The method gets rid of the chemical oxidation of the strong acid and strong oxidant; greatly reduces by-products and impurities; provides convenient separation and purification; reduces technical steps; shortens the processing time of mechanical ball milling; reduces energy consumption; greatly improves the yield; is fast, simple, convenient and environment-friendly; and provides high efficiency. DETAILED DESCRIPTION - Preparation of graphene oxide, involves: mixing graphite raw material and oxidant by mechanical action and oxidation reaction.
