Abstract

The invention discloses a preparation method of a graphene film. The preparation method comprises the steps: firstly, dissolving polymethyl methacrylate into acetone to obtain a polymethyl methacrylate and acetone liquid; then, dropwise adding the polymethyl methacrylate and acetone liquid on a metal to form a layer of polymethyl methacrylate film; covering a quartz glass slide on the polymethyl methacrylate film; then, simultaneously placing the metal sheet, the polymethyl methacrylate film on the metal sheet and the covered quartz glass slide into a high-temperature annealing furnace with a nitrogen condition, and carrying out high-temperature annealing while controlling the temperature at 800-1000 DEG C, wherein the polymethyl methacrylate is decomposed into a graphene film under the catalytic action of the metal in the metal film, and the graphene film is evaporated at a high temperature and is transferred on the quartz glass slide; and next, naturally cooling to room temperature to obtain a layer of graphene film on the quartz glass slide. The preparation method disclosed by the invention is simple and convenient to implement and capable of transferring graphene under the condition that the graphene is not damaged or polluted.
