The hydrogen storage ability of rice volume, and between graphene nano volume layer under key effect, adjustable interlamellar spacing can influence graphene nano volume
Electronics shifts and optical characteristics.Therefore, graphene nano rolls up oneself as one of study hotspot of graphite alkenyl nanometer materials.Mesh
Before, the preparation and application of graphene nano volume far lag behind graphene and CNT, on the one hand due to graphene Feedstock treating
Not ideal enough, on the other hand whole preparation technology is complicated, and operation is unmanageable.In consideration of it, it is badly in need of exploring new technique or equipment
Grapheme material is improved, to improve the performance of grapheme material.
The content of the invention
For above-mentioned technical problem, the present invention provides a kind of graphene Feedstock treating side for improving Feedstock treating effect
Method.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of graphene material processing, it is wrapped
Include following steps：
（1）Sulfuric acid solution and salpeter solution are poured into container and mixed, then the container is placed in the tank of water bath device；
（2）Ice bag is added into tank, using the solution in stirring rod stirring container, makes it well mixed；
（3）Graphene raw material is added into said vesse, then to broadcasting sowing potassium permanganate powder in container, and uses above-mentioned stirring
Rod continues to stir；
（4）Ice bag is taken out, distilled water is added into container, and the water in water bath device is heated container；
（5）The solution in said vesse is filtered again, obtains graphene oxide.
Preferably, the mass concentration of the sulfuric acid solution, salpeter solution is 96%, sulfuric acid solution and salpeter solution
Volumetric usage ratio is（2-5）:1.
Preferably, the mass ratio of the graphene raw material and potassium permanganate is 1：（4-7）.
Preferably, solid-to-liquid ratio is 1：（15-30）.

Preferably, having heaters is set in the water bath device.
Preferably, the potassium permanganate powder is broadcasted sowing by the stirring slurry of rotation.
As can be known from the above technical solutions, the present invention, which first passes through, is stirred solution, then adds graphene raw material and Gao Meng
Sour potassium, and ice-water bath is carried out to it by ice bag, on the one hand the cost using ice bag is low, workable, another aspect ice bag
It can be distributed in tank, the uniformity of temperature can be improved so that dissolving is more abundant.
Embodiment
The present invention is described in detail below, illustrative examples of the invention and explanation are used for explaining the present invention herein, but
It is not as a limitation of the invention.
A kind of graphene material processing, it comprises the following steps：
First, sulfuric acid solution and salpeter solution are poured into container and mixed, then the container is placed in the tank of water bath device；
The sulfuric acid solution, the mass concentration of salpeter solution are 96%, and the volumetric usage ratio of sulfuric acid solution and salpeter solution is（2-5）:
1, be advantageous to the processing of graphene raw material.In implementation process, ice bag can be also first added into tank, then place container；Also may be used
Bag on the rocks again after container is placed, then using the solution in stirring rod stirring container, makes it well mixed.It is preferably, described
Ice bag is strip, can be distributed around container perisporium, make circumferential Temperature Distribution more uniform, and the ice bag is the number being axially distributed
Bar, make Axial Temperature Distribution uniform.
Then, graphene raw material is added into said vesse, then to broadcasting sowing potassium permanganate powder in container, and using upper
Stirring rod is stated to continue to stir；The mass ratio of the graphene raw material and potassium permanganate is 1：（4-7）；Solid-to-liquid ratio is 1：（15-30）；
Be advantageous to graphene raw material fully to dissolve.In implementation process, the potassium permanganate powder is spread by the stirring slurry of rotation
Broadcast, the agitating paddle of rotation can be by potassium permanganate powder uniform broadcasting in container using centrifugal force so that potassium manganate powder is quick
Dissolving, not only improves efficiency, and can realize auto feed.
After the interior ice pellets of ice bag melts, ice bag is taken out, distilled water is added into container, and make the water pair in water bath device
Container is heated, and is reacted the solution in container；In implementation process, having heaters is set in water bath device, can be right
Water is heated, and ensures the uniformity of reaction temperature；After question response is complete, then the solution in said vesse is filtered, from
And obtain graphene oxide.
Above-mentioned embodiment is used for illustrative purposes only, and is not limitation of the present invention, relevant technical field
Those of ordinary skill, can be so that various changes can be made and modification without departing from the spirit and scope of the present invention, therefore institute
There is equivalent technical scheme also to belong to scope of the invention.
