▎ 摘　　要

NOVELTY - Method of isolating graphene oxide involves forming a graphene oxide dispersed liquid by dispersing graphene oxides in water, depositing the dispersed graphene oxides in graphene oxide dispersed liquid through coagulation with each other by adding salts in the graphene oxide dispersed liquid, isolating graphene oxides, which are deposited based on concentration of salt solution, from graphene oxide dispersed liquid and removing residual salts by purifying the isolated graphene oxides. The salt solution is formed by dissolving salts in the graphene oxide dispersed liquid. USE - Method of isolating graphene oxide used for forming oxidized graphene powder (claimed) for forming high-quality transparent electrode. ADVANTAGE - The method efficiently and economically isolated graphene oxide. DESCRIPTION OF DRAWING(S) - The drawing shows the flowchart of method of isolating graphene oxide.
