Description
Technical field
The utility model relates to the mass production facilities of Graphene.
Background technology
Graphene (Graphene), also known as mono-layer graphite, be a kind of by carbon atom with sp
2hybridized orbital composition hexangle type is the flat film of honeycomb lattice, is the two-dimension nano materials only having a carbon atom thickness.Although the discovery of Graphene only about 10 years, cause the research and development tide of the another ripple of a ripple have swept the globe.Graphene is a kind of two dimensional crystal tightly packed by carbon atom, has the features such as magical electric transmission, conduction, heat conduction and machinery.The physicist An Deliehaimu of Univ Manchester UK in 2004 and Constantine Nuo Woxiaoluofu, successfully from graphite, Graphene has been separated in laboratory, demonstrating Graphene can Individual existence, therefore win Nobel Prize in physics in 2010, thus start the global research boom of Graphene preparation, modification and application.Graphene is used for the application prospect of the aspects such as ultracapacitor, transparency electrode, lithium ion battery, sensor, functional paint and polymer nanocomposites, opens the New Times of grapheme material.
As there being scholar to say, 19th century were epoch of ironware, and 20th century were epoch of silicon, and 21 century is epoch of carbon.Carbon is one of element that distributed in nature is the most general, is to form the most important element of all life body on the earth.The characteristic of carbon material almost contains the character of all substances on the earth.Advanced carbon material has novel texture and excellent physical and chemical performance, is to have novel material that is great and decision meaning to future development.
New material industry, as one of the emphasis of emerging strategic industries, is also foundation stone and the guide of following Hi-tech Industry Development, is the important foundation that China becomes production power of the world.Graphene is as advanced carbon material, and it is the current top quality in the world material found.It has following characteristics: the thinnest, and 0.35nm is called as the material that the world is the thinnest now; Specific surface area is maximum, 2620m
2/ g; The hardest, rigidity is better than diamond, is the material that mankind's known strength is the highest, harder than iron and steel 100 times; Most tension, can elastic stretching 20%; Thermal conductivity is the highest, 5300W/m.k; Most high mobility 200,000cm
2/ v.s (300k); High light transmittance, transmittance is 97.7%/individual layer; High current carrying capacity: high 6 orders of magnitude of current density ratio copper; The most peculiar, Graphene is two-dimentional quantum material, linear band dispersion, and carrier effective mass is zero, can observe quantum hall effect under greenhouse; Also there is room temperature ballistic transport characteristic.
Graphene has infinitely wide application prospect, although the present potential stage, generally application does not also open up new prospect with industrialization, but from the angle of scientific forecasting, has become very important major fields.Such as, it is alternative and solve the drawbacks such as traditional lithium cell charging speed is slow, power reservoir capacity is poor, the life-span is short, pollution, can solve the crucial problem of Development of Electric Vehicles, make New-energy electric vehicle flourish.For another example can substituted for silicon, manufacture future new era supercomputer; Substitute ITO transparent conductive film, be applied to the electronics industry such as touch-screen, Flexible Displays, solar cell; Also can be applicable to sea water desaltination, degradable plastics, heat dissipation film, corrosion protection coating, biomaterial, matrix material, panel computer, wrist-watch calendar, mobile telephone, photodetector, graphene paper, Graphene cloth and space flight military project, ultralight flak jackets, ultra-thin and ultra-light aircraft, ultra-thin folding cell phone, the sky elevator etc. that even has imagination.The demand that Graphene is created, very likely starts a subversiveness new technology new industrial revolution of have swepting the globe.From global development trend, no one is ready that losing Graphene develops the major opportunity brought.
The mode preparing the current comparative maturity of Graphene has Physical and chemical method, wherein the Typical Representative of Physical obtains from graphite crystal by the mode of adhesive tape sticking, this method can obtain structure very perfectly Graphene crystal, relatively be applicable to exploitation electron device or physical study, cannot volume production.Volume production mainly relies on chemical method, a kind of for film former shape Graphene " from bottom to top " method, is namely assembled into graphene film from small molecules or carbon atom by approach such as chemical vapour deposition, epitaxy or organic syntheses.This method scale is relatively easily done greatly, to obtain the crystalline structure of Graphene relatively complete, be applicable to the transparent conductive film doing touch-screen or solar cell, and be difficult to the preparation being applied to powder Graphene.Another kind of mode is exactly " from top to bottom " method, is sometimes also chemical stripping method, utilizes intercalator that the Van der Waals force of each for the graphite crystal of three-dimensional interlayer is disintegrated exactly, graphite is disassembled out layer by layer, shells into which floor graphene product of individual layer or minority.Operational path and the intercalator used of current each producer are differentiated.Some salt intercalations then liquid phase are peeled off, and Graphene oxygen level prepared by this method is low, conduct electricity very well, but extent of exfoliation is relatively lower, and specific surface area is not too large; Then some initial oxidation intercalations are peeled off, and this method extent of exfoliation is high, and specific surface area is large, but the Graphene defect made is many, and oxygen level is large, constrains the process of industrialization of Graphene.
