Claim:
1. A method for producing functionalized graphene, comprising: combining a crystalline graphite with a first electrolyte solution, the first electrolyte solution including at least one of a metal hydroxide salt, an oxidizer, and a surfactant; milling the crystalline graphite in the presence of the first electrolyte solution for a first time period to produce a thinned intermediate material; combining the thinned intermediate material with a second electrolyte solution, the second electrolyte solution including a strong oxidizer and at least one of a metal hydroxide salt, a weak oxidizer, and a surfactant; and milling the thinned intermediate material in the presence of the second electrolyte solution for a second time period to produce a functionalized graphene.
