| 摘要 | 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 d0; 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/cm2, and wherein the thickness d is greater than the thickness d0. In one embodiment, the thickness d≧10×d0. | ||

| 主权项 | 1. A method for reducing a film of graphite oxide, comprising: (a) providing a film of graphite oxide with a thickness d0; and (b) delivering optical energy in a single pulse from a flash lamp 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/cm2, and wherein the thickness d is greater than the thickness d0. | ||
