▎ 摘  要

NOVELTY - Producing reduced oxidized graphene dispersion solution, comprises (a) preparing oxidized graphene dispersion solution by adding first dispersion medium into oxidized graphene powder, and dispersing, (b) reducing oxidized graphene by adding hydrazine hydrate into the obtained oxidized graphene dispersion solution, (c) washing the reduced oxidized graphene with water, and (d) adding second dispersion medium and dispersant into the washed reduced oxidized graphene, and dispersing. USE - The method is useful for producing reduced oxidized graphene dispersion solution (claimed). ADVANTAGE - The method produces reduced oxidized graphene dispersion solution having improves dispersion stability.
