Abstract:
A method of reducing a film of graphite oxide. In one embodiment, the method includes the steps of providing a film of graphite oxide with a thickness d; and delivering optical energy in a single pulse to the film of graphite oxide at a distance no more than 1.0 cm away from the film of graphite oxide to reduce the film of graphite oxide to a film of graphene with a thickness d, wherein the optical energy has a radiant exposure in the range of between 0.1 and 2 J/cm, and wherein the thickness d is greater than the thickness d. In one embodiment, the thickness d≧10×d.
