Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that there is only one winding mechanism when the graphene film is wound in the prior art. When the winding roller needs to be replaced, the machine needs to be shut down, and the winding cannot be continued until the replacement is completed, which seriously reduces the work disadvantages of efficiency, while the proposed method for the preparation of a graphene thin film

Abstract

The invention belongs to the field of production of graphene films, and particularly discloses a preparation method of a graphene film. In order to solve the problems that only one winding mechanism is applied during winding of an existing graphene film, people need to stop a machine when a winding roller needs to be replaced, and winding cannot be continued until replacing is completed, so that work efficiency is severely reduced, now the scheme is put forward as follows: the preparation method of the graphene film includes the following steps of S1, adding graphene oxide to deionized water to be evenly stirred and mixed to prepare a graphene solution; and S2, spray-coating the film with the graphene solution, drying the film, and winding the film through two winding devices, wherein thewinding devices are used alternately, when one winding device winds the film, the weight of the winding device is monitored through a weight sensor, and when the weight reaches a preset value, a cut-off mechanism cuts off the film. By alternately using the two winding devices, production efficiency can be improved, and meanwhile the film can be prevented from being stained with dust.
