Description
Technical field
The present invention relates to a kind of Graphene can be recycled.
Background technology
Graphene is the nano-carbon material with hexagonal lattice polynuclear plane being formed with sp2 hybrid form bonding by monolayer carbon atom, belongs to a kind of novel two dimensional crystal material.Graphene has good electroconductibility, thermal conductivity, optical transmission and special mechanical characteristic and electronics property, all has good application prospect in fields such as energy storage, electrically conducting transparent device, matrix material and opto-electronic devices.Therefore, Graphene has become the study hotspot in multiple ambits such as materialogy, physics and chemistry at present.
The preparation method of Graphene mainly comprises that mechanically peel method, chemical Vapor deposition process, oxidation intercalation restore method and liquid phase stripping method.Wherein mechanically peel method and chemical Vapor deposition process all can obtain high-quality Graphene, but productive rate is low, and these two kinds of methods are mainly used to provide required Graphene sample for theoretical investigation at present.It is to produce at present the main stream approach of Graphene in enormous quantities that oxidation intercalation restores method, but due to structural damage in oxidising process, this method is difficult to obtain high-quality Graphene product.Liquid phase stripping method is that the people such as Coleman in 2008 are at NatureNanotechnology3, a kind of method of preparing high-quality graphene of reported first in 563-568 (2008), its principle is in suitable solvent, utilize ultrasonic energy to dissociate to graphite flake layer, obtain the Graphene of 1-10 atomic layer level thickness.Compared with additive method, liquid phase stripping method is a kind of method that is expected to prepare in enormous quantities high-quality graphene.But, research shows, solvent stripping method prepares the productive rate of Graphene and the relation of solvent is very large, generally selects N-2-methyl-2-pyrrolidone (NMP), N,, there is the problem that is difficult to remove residual solvent in the high boiling organic solvents such as dinethylformamide (DMF).In addition, even if select suitable solvent, it is generally very low that simple solvent is peeled off productive rate, and further raising is peeled off productive rate and need to be added inorganic salt, alkali or tensio-active agent etc., also has the problem of removal of impurities.
Therefore, the present invention intends developing one and is suitable for common solvent, particularly lower boiling, easily removes solvent, and productive rate is high, the simple liquid phase stripping means of technique, and these a large amount of preparations for high-quality graphene are significant.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Graphene can be recycled.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The Graphene can be recycled, is characterized in that, comprises the material of following parts by weight: benzoyl peroxide 5-12 part, silicon carbide 5-8 part, vanadium phosphate 3-5 part, methacrylic acid silver 3-6 part, trimellitic acid nonyl polyhexamethylene 11-16 part, n-butyl stearate 10-17 part, phenylformic acid diethylene glycol ester 20-35 part, solution polymerized butadiene styrene rubber 20-26 part, hexabromo water prose style free from parallelism 5-9 part, graphite 55-65 part, water 65-81 part.
The invention has the beneficial effects as follows: technique of the present invention is simple, can in various polarity solvent, carry out, gained Graphene quality is good, and can be recycled as the graphene quantum dot of up-stripping.
