Abstract

See full text

A method of preparing graphene sheets. The method includes: immersing a portion of a first electrode and a portion of a second electrode in a solution containing an acid, an anionic surfactant, a salt, an oxidizing agent, or any combination thereof as an electrolyte, the immersed portion of the first electrode including a first carbon material and the immersed portion of the second electrode including a second carbon material or a metal; causing a potential to exist between the first and second electrodes; and recovering, from the solution, graphene sheets exfoliated from the carbon material(s). Also disclosed is a method of preparing a graphene film electrode. The method includes: dissolving graphene sheets in an organic solvent to form a solution, applying the solution on a substrate, adding deionized water to the solution on the substrate so that a graphene film is formed, and drying the graphene film.
