PROBLEM TO BE SOLVED: To provide a method for obtaining graphene oxide with a high functionalization level and with a high monolayer content (>99.8%), which has a short production time, a high total production yield, and environmental friendliness, and which is scaled up easily.SOLUTION: A method for obtaining graphene oxide includes a step of a) adding an acid and a salt to graphite for obtaining a graphite oxide, and a step of b) exfoliating the graphite oxide by mixing the graphite oxide, in which the steps a) and b) are carried out simultaneously in a high shear mixer. Preferably, the acid is sulfuric acid and the salt is potassium permanganate and no other components are added.SELECTED DRAWING: None |
