The application of film coating machine in the coating of graphene oxide film is mainly used to prepare high-quality graphene oxide film, which is a very promising two-dimensional material.
Membrane method
The film making method of the film coating machine generally includes the following steps:
Material preparation: Mix graphene oxide powder with a solvent to obtain a uniform graphene solution.
Adjust the coating head: select the appropriate coating head according to the needs, adjust the angle of the coating head, coating speed and other parameters.
Coating: Coating the graphene oxide solution onto the substrate. During the coating process, the coating head should be kept horizontal, and the coating speed should be properly controlled to ensure uniform coating.
Drying: Place the coated substrate at an appropriate temperature to dry.
Baking: Put the dried sample in an oven for baking to convert graphene oxide into reduced graphene.
The film coating machine can adjust the angle and coating speed of the coating head according to different needs to obtain graphene oxide films of different quality and thickness. Graphene oxide thin films are prepared by a film coating machine, and high-quality, high-reproducibility samples can be obtained.
