| description | The invention discloses a preparation method of graphene and an application of the preparation method. The method comprises the steps: clamping graphite paper with the (002) texture in the middle of apure copper sheet, and carrying out continuous multi-pass accumulative ply rolling on the pure copper sheet at room temperature under the condition of no lubrication. The graphite paper has a specific texture, namely layers in the graphite paper are parallel to each other and are parallel to the rolling direction; under the action of a rolling force, severe plastic deformation happens to the purecopper sheet, so shearing stress parallel to the rolling direction is borne between layers of the graphite paper, the shearing stress is greater than a Van der Waals force between the layers in the graphite paper, and the layers of the graphite paper begin to be stripped in the direction parallel to the rolling direction; the graphite paper is thinned layer by layer along with increase of rollingpasses, and finally the gr |
