The Introduction of graphene oxide dispersions

Graphene oxide dispersions can build the largest concentration of 2 mg / ml of graphene oxide , graphene oxide solution of graphene oxide films prepared from the precipitation does not occur.
Dispersion behavior of graphene oxide in different organic solvent impact . As-prepared graphite oxide may be dispersed , N-dimethylformamide, N-methyl-2-pyrrolidone, tetrahydrofuran , ethylene glycol . In all of these solvents , all of the stratum corneum is divided into individual graphite oxide materials , single-layer graphene oxide film group , was achieved. Exhibited dispersed graphene oxide sheets between the long-term stability and a few hundred nanometers and several microns large , a similar situation dispersed graphene oxide in water . These results should be easy to handle and deal with the graphene-based materials used in different environments .
