Problems solved by technology

[0003] The existing graphene film often has the following problems in the production process: a: the existing graphene film often has uneven coverage of graphene on the film surface during production, which greatly affects the graphene film. The quality of the graphene film; b: when the existing graphene film is coated, it is often due to the presence and dirt on the surface of the graphene film, which leads to a blind area when the graphene powder is covered, which affects the coating effect of the graphene powder and reduces the graphite olefin film quality

Abstract

The invention relates to a preparation method of a graphene film. The preparation method mainly comprises the following steps of equipment inspection, material preparation, film conveying, surface spraying and excess material removal. Graphene film forming equipment comprises a mounting frame, a traction set and a spraying set, and the traction set and the spraying set are sequentially arranged on the mounting frame from outside to inside. According to the invention, the following problems in the production process of an existing graphene film can be solved: a, graphene on the surface of the film is often not uniformly covered when the existing graphene film is produced, so that the quality of the graphene film is greatly influenced; and b, when the existing graphene film is laminated, the surface of the graphene film is often dirty, so that a blind area appears when the graphene powder is covered, the laminating effect of the graphene powder is further influenced, and the quality of the graphene film is reduced.

Description

technical field [0001] The invention relates to the technical field of film preparation, in particular to a method for preparing a graphene film. Background technique [0002] Graphene film is a material with high thermal conductivity and high flexibility. It is widely used in the fields of aerospace and mobile computers. As the world enters the era of technology, mobile phones have almost become consumables. With the high demand for mobile phones, the demand for graphene films is also gradually increasing. The existing graphene films need to carry out equipment inspection, material preparation, film transportation, surface spraying and residual material removal during the production process. [0003] The existing graphene films often have the following problems in the production process: a: the existing graphene films often have uneven coverage of graphene on the film surface during production, which greatly affects the graphene film. The quality of the graphene film; b: w...
