|1. (WO2013111947) METHOD FOR ISOLATING GRAPHENE OXIDE|
|Applicants:||KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
|Title:||METHOD FOR ISOLATING GRAPHENE OXIDE|
The present invention provides a method for isolating graphene oxide comprising the steps of: (a) forming a graphene oxide dispersed liquid by dispersing graphene oxides in water; (b) depositing the dispersed graphene oxides in the graphene oxide dispersed liquid through coagulation with each other by adding salts in the graphene oxide dispersed liquid; (C) isolating the graphene oxides, which are deposited according to the concentration of the salt solution, from the graphene oxide dispersed liquid, wherein, the salt solution is formed by dissolving the salts in the graphene oxide dispersed liquid; and (d)removing residual salts by purifying the isolated graphene oxides.
