Abstract
Provided is a method of forming a uniform graphene layer on a substrate (metal- or conductive-polymer-coated, ITO) by doping expanded graphite using various kinds of dopants (Lewis acid) to grant a positive charge thereto, dispersing the doped expanded graphite in an organic solvent using ultrasonic waves to obtain a solution in which the graphene is dispersed in the organic solvent, and electrically applying a negative voltage to the solution.
