Abstract
The invention discloses a lamina graphene production method. The lamina graphene production method comprises the steps that (1) crystallized graphite and a grinding medium are placed into a ball milling container; (2) a first solvent and a second solvent are transferred into the ball milling container; and (3) the ball milling container is made to rotate to conduct ball milling to obtain thinned crystallized graphite, namely, lamina graphene. According to the lamina graphene production method, thinned crystallized graphite prepared from crystallized graphite through a wet ball milling method has a high specific surface area and excellent physical properties and is simple in production method. The production efficiency is improved. Environmental pollution is reduced. Energy is saved.
Description
Technical field
The present invention relates to thin graphene technical field is produced, more particularly to a kind of method for producing thin graphene.
Background technology
The carbon atom that Graphene is intensive by one layer, be wrapped in Nidus Vespae crystal lattice is constituted, and is most thin in the world
Two-dimensional material, with very excellent performance：The specific surface area of super large, theoretical value 2630m2/g；High intensity, is material of having measured and monitored the growth of standing timber
Middle intensity highest, is more than 100 times of iron and steel up to 1TPa；Electric property is excellent, under room temperature electron mobility up to 2 ×
105cm2/( V·s )；Thermal conductivity is 5300Wm-1·K-1, it is three times of diamond, also there is in addition room temperature in terms of electromagnetism
The special natures such as quantum hall effect, ferromagnetism and superconductivity effects.These excellent performances make Graphene in transistor, solar energy
There is good application prospect in the fields such as battery, fuel cell, sensor, ultracapacitor and catalyst carrier.Therefore Graphene
Preparation become the premise of the application of border in fact.
At present, with regard to the existing substantial amounts of report of preparation method of Graphene, but every kind of method can not be into because itself limiting
To prepare the Perfected process of Graphene.Complicated process of preparation is there is in existing method, power consumption is big, and the Graphene for preparing
There is the structure of a large amount of aggregations.Chemical stripping method be macroscopic preparation of graphene method in simpler method, current operation
Prepare in technology graphite oxide time it is longer and aoxidize it is insufficient.Additionally, in from graphite oxide to Graphene preparation process often
The method seen has the methods such as hydrazine hydrate reduction and high-temperature heat expansion.But the hydrazine hydrate that both technologies are used is poisonous, environment
Unfriendly, and high energy consumption, preparation process takes, and is not suitable for industrialized production.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of method for producing thin graphene.
The present invention is achieved by the following technical solutions：
A kind of method for producing thin graphene, preparation process is：
（1）Kish and abrasive media are put in ball mill container；
（2）First and second solvents are transferred in ball mill container；
（3）Make ball mill container rotate ball milling, obtain thinning kish, i.e. thin graphene.
The abrasive media is 1 with the mass ratio of kish：1-80.
First solvent and the second solvent include any two kinds in water, heptane, ethanol and acetonitrile, the first solvent and the
The volume ratio of two solvents is 1：1-20.
The ball mill container rotates 2-100 hours, and the rotary speed of grinding container is for about 10-225rpm.
The ratio of the cross sectional dimensions of kish and the thickness of final products is 100-2000.
It is an advantage of the invention that：The present invention is obtained plus thin kish using wet ball mill method by kish, with height
Specific surface area, excellent physical property, production method is simple, improves production efficiency, reduces environmental pollution, saves energy
Source, the method green is simple, and saves time cost, therefore can carry out large-scale production and application, should with extensive industry
Use prospect.
