DETAILED DESCRIPTION - Preparing graphene by continuous spray coating of graphite powder liquid carbon dioxide suspension, comprises a sealed tank, a sealed barrel, a stirrer, a feeding port, an output pipe, a linear nozzle, a roller, a roller and a graphene sheet, adding liquid carbon dioxide with ultra-low viscosity, ultra-strong fluidity, super-strong permeability, super-absorption, specific gravity 1.101, boiling point -78.5 degrees C, and nano-level, specific gravity 2.25 graphite powder to the precise measurement In a sealed tank with a stirrer, the graphite powder broken down into free carbon atoms and liquid carbon dioxide to form a uniformly mixed suspension during the stirring disturbance, during continuous stirring, the output tube and linear nozzles located in the middle and lower part of the side wall of the sealed tank evenly spraying on the surface of the rotating roller, depending on the specific gravity difference of the carbon atoms in the liquid carbon dioxide, the carbon that reaches the roller surface first atoms in a three-dimensional equilibrium environment without the kinetic energy of the upper and lower atoms, completing the two-dimensional combination in the lateral direction to form a two-dimensional crystal, liquid carbon dioxide quickly evaporates due to the huge temperature difference in the room temperature environment, forming a graphene membrane attached to the surface of the roller, which is peeled off under the flush of liquid carbon dioxide at the linear nozzle connected to the sealed barrel, wound on a roller to complete the graphene production.
