摘要：Problem to be solved: to provide a stable type of a graphene dispersion or a preparation method for at least one month without using a dispersion additive for various solvents. Solution: the method of preparing an oxide graphene dispersion
includes the following steps (1) to (3), removing impurities such as unoxidized oxide graphite, dispersing only the single layer of graphed oxide graphene, and preventing the dispersion in the solvent other than water in the monolayer delamination process Features: (1) the process of obtaining a graphite oxide aqueous dispersion containing single layer graphene by stripping the surface of the oxidized graphite in water. (2) the process of removing the precipitates by centrifuging the aforementioned oxidized graphite water dispersion solution to recover supernatant and obtaining a single layer graphene aqueous dispersion solution. (3) the solvent substitution process in which the single layer oxide graphene aqueous dispersion is subjected to solvent substitution treatment with water or organic solvent. Diagram
