Problems solved by technology
[0003] The concentration of the graphene dispersion is very low, the size of the graphene sheet is too small, the excess dispersant is difficult to remove, and the organic solvent with a high boiling point is difficult to volatilize. When the graphene is deposited on the substrate to prepare a film, the solvent volatilization rate is too slow It will cause graphene to agglomerate, and it is difficult to obtain a single-layer or few-layer graphene film

The invention discloses a graphene thin film preparation device which comprises a reel framework and a solution cabin, wherein a supporting rod is welded to the front end in the reelframework, limiting teeth are welded to the surface of the top of the supporting rod, a snap spring is connected to the sides of the surfaces of the limiting teeth, a bearing is annularly connected in the snap spring,a thin film reelis connected to the central position in the bearing, and a thin film is annularly connected to the surface of the thin film winding shaft. According to the graphene thin film preparation device disclosed by the invention, the thin film reel which the thin film is wound to is arranged between the limiting teeth arranged in the reel framework, the snap spring is arranged between thelimiting teeth, and the two ends of the thin film reel are connected with the bearing; the bearing is clamped in the snap spring, so that the thin film reel is fixed, and the thin film reel can be conveniently fixed, assembled and disassembled; then the thin films are guided into equipment, and an upper layer and a lower layer are arranged in the reel framework to simultaneously perform graphene thin film preparation on the two rolls of thin films; thus, the graphene thin film production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of graphene film preparation, in particular to a graphene film preparation device. Background technique [0002] Graphene is a single-layer atom-thick carbon material. Each carbon atom forms a bond with three adjacent atoms through sp2 mixing, and extends into a honeycomb two-dimensional structure. And graphene is also known for its good carrier mobility. Because of its excellent electrical properties, chemical stability, bendability, good thermal conductivity and high penetration rate, graphene has been widely used in semiconductors. , touch panels or solar cells and other fields. [0003] The concentration of the graphene dispersion is very low, the size of the graphene sheet is too small, the excess dispersant is difficult to remove, and the organic solvent with a high boiling point is difficult to volatilize. When the graphene is deposited on the substrate to prepare a film, the solvent volatilization r...
