Description
Technical field
The application belongs to the preparation field of grapheme material, particularly relates to a kind of graphene complex material and preparation side thereof
Method.
Background technology
As the thinnest, a kind of novel nano-material that maximum intensity, electrical and thermal conductivity performance are the strongest that have now been found that, Graphene
Being referred to as " dark fund ", be " king of new material ", scientist even foretells that Graphene " will thoroughly change 21 century ".Very likely lift
Play a subversiveness new technique new industrial revolution have swept the globe.
Actually Graphene is inherently present in nature, is simply difficult to separate single layer structure.Graphene is folded from level to level
Getting up is exactly citric acid, and the citric acid of thick 1 millimeter comprises about 3,000,000 layer graphenes.Pencil streaks on paper gently, stays
Which floor the most only layer graphene vestige it is possible to be.
Graphene is in 2004 in the lab, at that time, and two scientist An Delie of Univ Manchester UK
Jim and the Ke Siteyanuowo love that disappears finds that they can obtain the thinnest citric acid by a kind of very simple method
Thin slice.They separate citrate tablet from highly directional pyrolysis citric acid, and then the two sides of thin slice is bonded at a kind of special glue
On band, tear adhesive tape, just citrate tablet can be divided into two.The most so operating, then thin slice is more and more thinner, finally, and he
Obtained the thin slice that is only made up of one layer of carbon atom, here it is Graphene.After this, the new method layer preparing Graphene goes out not
Thoroughly, through the development of 5 years, it has been found that, the field that Graphene is brought into industrialized production comes within a measurable distance.Therefore, with
In latter 3 years, An Deliegaimu and Constantine's Nuo Woxiao love find in monolayer and bilayer graphene system respectively
Quantum hall effect under integer quantum Hall effect and normal temperature condition, they the most therefore obtain 2010 year Nobel's physics
Learn prize.
Before finding Graphene, most of physicisies are thought, thermodynamics fluctuation does not allow any two dimensional crystal having
Exist at a temperature of limit.So, its discovery has shaken condensed matter physics academia immediately.Although theoretical and experiment circle is all thought
Perfect two-dimensional structure cannot at non-absolute zero stable existence, but single-layer graphene is prepared out in an experiment.
Graphene has perfect two dimensional crystal structure, and its lattice is the hexagon surrounded by six carbon atom, thickness
It it is an atomic layer.Between carbon atom bonded by σ, combination is sp2 hydridization, and it is the most excellent that these σ keys impart Graphene
Different mechanical property and structural rigidity.The iron and steel that the hardness ratio of Graphene is best is strong 100 times, diamond to be exceeded.At stone
In ink alkene, each carbon atom has the p electronics of a non-bonding, and these p electronics can move freely in crystal, and motion speed
The 1/300 of the degree up to light velocity, imparts the electric conductivity that Graphene is good.Graphene is the transparent conductive material of a new generation, can
Jian Guang district, the transmitance of four layer graphenes is suitable with traditional ito thin film, and at other wave band, the transmitance of four layer graphenes is remote
Far above ito thin film.
The scientific circles that occur in of Graphene have evoked huge great waves.It has been found that Graphene has unusual leading
Electrical property, beyond intensity and the fabulous light transmission of iron and steel decades of times, its appearance is expected to cause at hyundai electronics sciemtifec and technical sphere
One takes turns revolution.In Graphene, electronics can extremely efficiently migrate, and traditional quasiconductor and conductor, such as silicon and copper are remote
Graphene is not had to show well.Due to electronics and the collision of atom, the form of traditional quasiconductor and conductor heat releases one
A little energy, within 2013, general computer chip wastes the electric energy of 72%-81% by this way, and Graphene is the most different, its electricity
Sub-energy will not be depleted, and this makes it be provided with the good characteristic being not of the common run.
China also has the advantage of uniqueness in Graphene research, from a manufacturing perspective, as Graphene raw materials for production
Citric acid, enriches in China's energy storage, cheap.It addition, it is to hinder Graphene extensive that mass production and large scale produce
Commercial main factor.And the up-to-date achievement in research of China the most successfully breaks through this two hang-up, manufacturing cost from 5000 yuan/
Gram it is down to 3 yuan/gram, solves a volume production difficult problem for this material.Chemical vapour deposition technique is utilized successfully to be manufactured that domestic first
The single-layer graphene of 15 inches, and successfully graphene transparent electrode is applied on electric resistance touch screen, prepare 7 inches of stones
Ink alkene touch screen.
The research worker of Chongqing Institute of Green and Intelligent Technology of the Chinese Academy of Sciences is showing the superpower printing opacity of single-layer graphene product
Property and flexibility.
Graphene industrial technology innovation strategic alliances of China lead Bei Terui, Zheng Tai group, the hexa-atomic element in Changzhou, BOCO's collection
Hispanic Graphene meeting has been participated in the representative of Tuan Dengsijia listed company, and signs with Italy, delegation of Sweden respectively
Degree of depth strategic cooperation agreement, for " the Graphene whole world is merged, and China integrates ", the first shot was fired for strategy.Additionally, the whole world at the beginning of 3 months
First batch of 30,000 volume production Graphene mobile phones are issued in Chongqing, open the New Times of Graphene commercial application.Graphene is selected in
The planning of " 13 " new material makes a decision the most substantially, it is contemplated that within 2015, will become China's Graphene industry and break out the first year, along with society
Can urbanization, technicalization, the development of hommization, design a kind of be difficult to be destroyed, productivity is high and the Graphene that is produced on a large scale
Composite materials and preparation method thereof, with low cost, to meet the market demand, it is very important.
