A method to fractionate and isolate components of oxidized graphene material, comprising: a. fractionating a system that includes graphene oxide, a solvent and water, wherein the fractionation creates two phases or fractions: (i) a water phase or fraction that contains highly oxidized graphene oxide, and (ii) a solvent-in-water emulsion phase or fraction that contains a graphene-based material; and b. separating the graphene-based material from the solvent-in-water phase or fraction to recover the graphene-based material. Currently amended
The method of claim 1, further comprising repeating the fractionating process on the solvent-in-water emulsion phase or fraction. Original
The method of claim 1, wherein the solvent is selected from the group consisting of heptane, toluene and chloroform. Original
The method of claim 1, further comprising using the graphene-based material (uGO) in an application selected from the group consisting of one or more of a medical device, a nanoelectronic, an electromechanical system, a sensor, a composite, a catalysis, and energy storage device, and an optics application. Original
Canceled
