▎ 摘 要
NOVELTY - Classification method of graphene oxide comprises preparing at least two graphene oxides having different sizes, dispersing the graphene oxide in organic solvent/water mixture, and separating the precipitate and supernatant dispersed in the mixture. USE - The method is useful for classification of graphene oxide. ADVANTAGE - The graphene oxide is simple to prepare and has good mechanical property. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the classification method of graphene oxide (Drawing includes non-English language text).
