▎ 摘　　要

NOVELTY - The method involves irradiating graphene oxide (GO) with a beam of light or radiation to form reduced graphene oxide (RGO) in a three-dimensional (3D) pattern, in which the RGO is porous RGO with pores having sizes tuned by controlling the beam of light or radiation. The GO includes layers of porous GO film, in which each layer of the porous GO film includes layers of porous GO sheets, and oxygen functional groups situated between two or more GO sheets. A portion of the oxygen functional groups is removed between the GO sheets by the irradiation. USE - Manufacturing method of capacitors, supercapacitors, and electrodes. ADVANTAGE - Provides the ability to accurately control the reduction process and the pore size and interlayer spacing in the porous reduced graphene oxide film, by the irradiation with the beam of light or radiation. Allows more efficient use of the area of the device, thus may enhance the overall energy density of the supercapacitor storing more energy within a limited volume.
