▎ 摘　　要

NOVELTY - Making graphene oxide or flakes comprises: placing graphite into water containing an oxidizing agent, where the oxidizing agent has an oxidation potential less than 2V; mechanically exfoliating graphite into graphene flakes; and separating the graphene flakes from the water, where the graphene flakes are substantially flat. USE - The method is useful for making graphene oxide or flakes (claimed). ADVANTAGE - The method provides graphene oxide or flakes in large scale with high quality. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide or flakes made by the method.
