▎ 摘 要
NOVELTY - Microwave pretreatment of high-dispersity graphene oxide includes placing graphite into microwave oven, and microwave treating; adding into concentrated sulfuric acid-containing three-necked flask together with sodium persulfate, water bath heating, stirring, suction filtering, washing repeatedly with deionized water until neutral, and oven-drying to obtain pre-oxidized graphite; and subjecting to Hummers' method. USE - Method for microwave pretreatment of high-dispersity graphene oxide (claimed). ADVANTAGE - The method is simple and has mild reaction condition. The graphene oxide has high dispersibility. DETAILED DESCRIPTION - Microwave pretreatment of high-dispersity graphene oxide comprises: (A) placing graphite into microwave oven, and microwave treating; (B) adding into 20 mL concentrated sulfuric acid-containing three-necked flask together with sodium persulfate, water bath heating, stirring, suction filtering, washing repeatedly with deionized water until neutral, and oven-drying to 60 degrees C for 24 hours to obtain pre-oxidized graphite; and (C) subjecting to Hummers' method.
