Description
Technical field
The present invention relates to field of nanometer material technology, and in particular to a kind of method that ball milling peels off white graphite alkene.
Background technology
White graphite alkene (h-BN) essence is the h-BN of individual layer or few layer.
The discovery of Graphene has triggered scientific circles to the research boom of two-dimensional material, and white graphite alkene piece is used as a kind of new
Two-dimensional material, because there is excellent performance widely to be studied for it.In two-dimentional h-BN, B atoms and N atoms with sp2 hydridization,
B and N presses 1:1 forms covalent bond, obtains the two dimensional surface of the side's honeycomb structure of class Graphene six, but it is on third dimension direction upper strata
Combined by Van der Waals force between layer, constituted Van der Waals stratified material.
Based on the unique two-dimensional structures of h-BN, two-dimentional h-BN materials possess many excellent performances.Two-dimentional h-BN density is low,
Specific strength is high, can apply to modified multifunctional composite;Coefficient of friction is low, is a kind of conventional lubricant;High temperature resistant,
Still possess chemical stability in 1000 DEG C of air above, can apply to the fields such as ORC;Thermal conductivity factor is big, can be used as leading
The filler of hot composite;Stratiform h-BN energy gaps are 5.0-6.0ev, with excellent insulating properties, individual layer H-BN tunnels
Its barrier height of the property in road 3.07eV, breakdown voltage 7.95MV/cm, with SO2Property it is close, and h-BN layer surfaces it is smooth,
Dangling bonds relatively less, carrier traps it is few, h-BN is the ideal carrier platform of grapheme transistor;Simultaneously because its energy gap
Greatly, it is also possible to make Ultra-Violet Laser sensitive detection parts.And h-BN is a kind of good gas sensitive, to CO2, CH4、O2, H2, NO2Deng tool
Standby high sensitivity.
Although h-BN two-dimensional materials possess above-mentioned many superperformances, at present for the extensive excellent h- of processability
BN still requires study.Prepared white graphite alkene (h-BN) yield of traditional micromechanics stripping is too low, is suitable only for Laboratory Production;Change
Learn liquid phase stripping etc. and commonly use poisonous and hazardous organic solvent, and oxidation and ion insertion etc. to its physical arrangement and electronic structure
There is certain influence, prepared h-BN electric properties are not good.Chemical vapor deposition is commonly used to prepare high performance individual layer or few
Layer h-BN, but its with high costs and yield is restricted.Current white graphite alkene still can not largely produce pure in the method for low cost
Degree is high, the white graphite alkene of function admirable, and this greatly limits its application, it is that current white graphite alkene grinds to improve white graphite alkene production capacity
One of emphasis studied carefully.Additionally, similar to many other nano materials, there is huge specific surface area in white graphite alkene, in Van der Waals
In the presence of power, the sector-meeting of white graphite alkene produces irreversible reunion, therefore its dispersive property has a strong impact on its performance and application, carries
H-BN dispersivenesses high are equally the emphasis of current research.
The content of the invention
In view of this, it is necessary to for above-mentioned problem, there is provided a kind of ball milling peels off the method for white graphite alkene, this method energy
White graphite alkene particle is effectively peeled off, the white graphite alkene that stripping is obtained has the spy that particle is uniform, the number of plies is few, area is big, purity is high
Point, good can be dispersed in alcohol equal solvent and preserve tens of days and do not produce reunion settlement action.And the method operating process letter
Single, low cost, production efficiency is high, suitable for mass industrialized production.
