GRAPHENE OXIDE, GRAPHENE OXIDE DISPERSION LIQUID AND METHOD FOR PRODUCING GRAPHENE OXIDE

摘要

PROBLEM TO BE SOLVED: To provide a graphene oxide that has high dispersibility and prevents the occurrence of structural defects.SOLUTION: A suspension comprising a carbon material having a graphene structure and an aqueous dispersion medium is plasma-treated in the liquid or on the liquid surface, to introduce a hydroxyl group and/or a carbonyl-containing group into graphene.SELECTED DRAWING: None
