▎ 摘　　要

NOVELTY - Producing graphene oxide comprises (a) introducing graphite, an oxidizing agent and acid solution into a Couette-Taylor reactor, and performing oxidation reaction to produce product containing oxidized graphite, and (b) separating and peeling oxidized graphite from the product. USE - The method is useful for producing graphene oxide (claimed). ADVANTAGE - The method shortens processing time, and is convenient to process, and environmentally friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for oxidized graphene production system comprising the Couette-Taylor reactor (120) for producing product containing oxidized graphite by introducing graphite, an oxidizing agent and acid solution into an input unit, and performing oxidation reaction, where the input unit is provided with a first pipe (110a) for introducing the graphite and acid solution into the reactor, and a second pipe (110b) for introducing oxidizing agent into the graphite and acid solution, and connected with the first pipe. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic representation of the oxidized graphene production system. First pipe (110a) Second pipe (110b) Couette-Taylor reactor (120)
