Application prospect.The method preparing at present graphene-based film mainly has: vacuum filtration method, LB method, spin-coating method and from group
Dress.And the limitation of current technology to be mainly manifested in (1) preparation technology complex；(2) cannot scale prepare continuously
Graphene-based film；(3) selectivity to target base plate is stronger.Cannot meet engineering to large area, low cost is graphene-based
The demand of film.
Content of the invention
Problem to be solved in the utility model is: for the deficiencies in the prior art, proposes a kind of based on gas blowout, can be extensive
Prepare the device of graphene-based film continuously.
The technical solution of the utility model is: the device of graphene-based film is prepared in a kind of scale, including air pump, spray gun,
Movable stand, target base plate and warm table, spray gun is arranged on movable stand, and air pump connects spray gun, and the nozzle of spray gun is towards mesh
Mark substrate, target base plate is arranged on warm table.
Further, warm table is additionally provided with roller devices.
It is preferred that, movable stand is the movable stand of Automated condtrol.
Spray gun is connected by the utility model with air pump, carrys out atomized soln by air pump.Spray gun is arranged on above movable stand admittedly,
Controlling it to move back and forth, the large area to realize object-oriented substrate sprays.Target base plate is placed on warm table, heating
Platform is used for heating target base plate, makes to drop into the droplet rapid evaporation in target base plate, accelerates the preparation process of film.

It is arranged on warm table 5.Warm table 5 is additionally provided with roller devices 6, may be provided at both sides or bottom, is used for graphene-based
The transmission of film, to realize prepared by serialization.
Operation principle of the present utility model is to spray to graphene dispersion solvent in the target base plate of preheating with spray gun, solvent
Obtain the process of graphene film after volatilization.The effect of spray gun is aerosol dispersion solvent, forms droplet, uses warm table
After preheating target substrate ensures droplet deposition to target base plate, solvent can evaporate rapidly, it is to avoid the reunion of graphene film,
Ultimately form graphene-based film.
Below by 2 embodiments, work of the present utility model is described.
Embodiment one:
It by graphene dispersion in N-N dimethylacetylamide, is prepared into the dispersion soln of Graphene.Dispersion soln is added
In spray gun, target base plate uses glass substrate, sprays to be previously heated to 200 by graphene solution under the promotion of air pump
On the glass substrate of degree, spray gun moves back and forth under the drive automatically moving frame and sprays, at the band of the roller of warm table
Under Dong, glass substrate constantly promotes forward, it is achieved prepare continuously, finally prepares large-area stone on the glass substrate
Ink alkene transparent conductive film.
Embodiment two:
Preparing graphene oxide aqueous liquid dispersion, joining in spray gun, target base plate uses filter paper, under the promotion of air pump
Graphene oxide solution is sprayed to be previously heated on the filter paper of 70 degree, spray gun under the drive automatically moving frame back and forth
Moving and spraying, under the drive of the roller of warm table, filter paper constantly promotes forward, it is achieved prepare continuously, finally exists
To be prepared for the graphene oxide film that absorptance is 94% on filter paper.
