Description
Technical field
The invention belongs to technical field of graphene preparation, and in particular to a kind of device and side that graphene is prepared using platinum filament
Method.
Background technique
Natural graphite alkene is the two dimensional crystal for being stripped out from graphite material, being made of carbon atom.Graphene is both
Most thin material, and most tough material, 200 times more taller than best steel of breaking strength.It has well again simultaneously
Elasticity, stretch range can reach the 20% of own dimensions.It is that current nature is most thin, the highest material of intensity, graphene mesh
Preceding most potential application is the substitute as silicon, manufactures ultra micro transistor npn npn, for producing following supercomputer.With
Graphene replaces silicon, and the speed of service of computer processor will be hundreds times fast.In addition, graphene be almost it is fully transparent,
Only absorb 2.3% light.On the other hand, it is very fine and close, even the smallest gas atom (helium atom) can not also penetrate.This
A little features make it be highly suitable as the raw material of transparent electron product, such as transparent touch display screen, luminescent screen and solar energy
Solar panel.As presently found most thin, maximum intensity, a kind of strongest novel nano-material of electrical and thermal conductivity performance, graphene
Referred to as " dark fund " is " king of new material ", and scientist even foretells that graphene " will thoroughly change 21 century ".
In the prior art, there are mainly two types of the preparation methods of natural graphite alkene: mechanical means and chemical method.Mechanical means

Method.
Most common is micromechanics partition method, directly cuts down graphene platelet from biggish crystal.2004
Novoselovt etc. has prepared single-layer graphene in this way, and can be stabilized under external environment.Typical case's preparation
Method is rubbed with the pyrolytic graphite of another material extruding or introducing defect, and the surface of body phase graphite can generate wadding
The crystal of sheet contains the graphene of single layer in the crystal of these flocculus shapes.But the disadvantage is that this method is to utilize friction graphite table
The thin slice that face obtains filters out the graphene platelet of single layer, and size is not easy to control, can not reliably supply enough factory length
Graphite flake sample.
Epitaxy method is to go out graphene using growth substrate atomic structure " kind ", and carbon atom is allowed to seep at 1150 DEG C first
Enter ruthenium, then cool down, after being cooled to 850 DEG C, a large amount of carbon atoms absorbed before will float to ruthenium surface, the single layer of lens shape
Carbon atom " isolated island " be covered with entire stromal surface, it is final they can grow up to complete one layer of graphene.First layer covering
After 80%, the second layer starts to grow.The graphene of bottom can generate strong reciprocation with ruthenium, and after the second layer just almost with
Ruthenium is kept completely separate, only remaining light current coupling, and obtained single-layer graphene thin slice performance is satisfactory.But it produces in this way
Graphene platelet it is often in uneven thickness, and the bonding between graphene and matrix will affect the characteristic of carbon-coating.
Chemical reduction method is to mix graphite oxide and water with the ratio of 1mg/mL, with supersonic oscillations to the clear nothing of solution
Particulate material is added appropriate hydrazine and flows back at 100 DEG C for 24 hours, generates black particle shape precipitating, filtering, graphene obtained by drying.
Chemical dissociation method is the method that graphite oxide is prepared graphene by the method heat-treated, the oxygen-containing function of graphite oxide interlayer
Group reacts at a certain temperature.
Wherein, electrolysis method is the most common method for preparing graphene, but there are graphene yield is too low, purity is not high
