Embodiment Construction
[0018] The present invention will be described in detail below, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.
[0019] A kind of graphene raw material processing method, it comprises the following steps:
[0020] First, pour sulfuric acid solution and nitric acid solution into the container and mix, then place the container in the water tank of the water bath device; It is (2-5): 1, which is beneficial to the processing of graphene raw materials. In the implementation process, you can also add ice packs to the water tank first, and then place the container; you can also place the container and then add ice packs, and then use a stirring rod to stir the solution in the container to make it evenly mixed. Preferably, the ice packs are strip-shaped and can be distributed around the peripheral wall of the container to make the temperature distribution in the circumferential...

The invention relates to a graphene material, in particular to a treatment method for graphene raw materials. The method comprises the following steps: pouring a sulfuric acid solution and a nitric acid solution into a container for mixing, and then putting the container into a water tank of a water bath device; adding ice bags into the water tank, stirring a solution in the container by adopting a stirring rod and enabling the solution to be sufficiently mixed; adding the graphene raw materials into the container, then spreading potassium permanganate powder into the container, and continuously stirring by adopting the stirring rod; taking out the ice bags, adding distilled water into the container, and heating the container by using water in the water bath device; carrying out suction filtration on the solution in the container to obtain graphene oxide. According to the treatment method disclosed by the invention, a mixed solution is stirred, then the graphene raw materials and potassium permanganate are added, and a mixture is subjected to ice-water bath by the ice bags; on one hand, the adopted ice bags are low in cost and high in maneuverability; on the other hand, the ice bags can be uniformly distributed in the water tank, so that the temperature uniformity can be improved, and the dissolving is more sufficient.
Description
technical field [0001] The invention relates to the field of graphene materials, in particular to a method for processing graphene raw materials. Background technique [0002] Graphene has attracted the attention of some researchers as a new type of nanostructure, named graphene nanoscrolls, which are helically coiled from planar graphene. In addition, the two ends and the inner and outer edges of the non-closed state can improve the hydrogen storage capacity of graphene nanoscrolls, and under the action of the interlayer bonds of graphene nanoscrolls, the tunable interlayer spacing can affect the electron transfer and optical properties of graphene nanoscrolls. characteristic. Therefore, graphene nanoscrolls have become one of the research hotspots of graphene-based nanomaterials. At present, the preparation and application of graphene nanoscrolls are far behind graphene and carbon nanotubes. On the one hand, due to the unsatisfactory handling of graphene raw materials, o...
