Description
Technical field
The application belongs to the preparation field of grapheme material, particularly relates to a kind of grapheme material and preparation method thereof.
Background technology
Graphene is in 2004 in the lab, at that time, and two scientist An Delie of Univ Manchester UK
Jim and Ke Siteyanuowo disappear, and to find that they can obtain by a kind of very simple method the thinnest to benzene two for love
Formaldehyde thin slice.They separate terephthalaldehyde sheet from highly directional pyrolysis terephthalaldehyde, are then bonded on the two sides of thin slice
On a kind of special adhesive tape, tear adhesive tape, just terephthalaldehyde sheet can be divided into two.The most so operate, then thin slice
More and more thinner, finally, they have obtained the thin slice being only made up of one layer of carbon atom, here it is Graphene.After this, prepare graphite
The new method of alkene emerged in an endless stream, through the development of 5 years, it has been found that, Graphene is brought into the field of industrialized production for time
Within sight.Therefore, in subsequently three years, An Deliegaimu and Constantine's Nuo Woxiao love are at monolayer and double-layer graphite
Being found that the quantum hall effect under integer quantum Hall effect and normal temperature condition in alkene system respectively, the most therefore they obtain
2010 annual Nobel Prizes in physics.
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
Terephthalaldehyde, enriches in China's energy storage, cheap.It addition, it is to hinder Graphene big that mass production and large scale produce
The main factor that scale is commercial.And the up-to-date achievement in research of China the most successfully breaks through this two hang-up, manufacturing cost from
3 yuan/gram are down to by 5000 yuan/gram, solve a volume production difficult problem for this material.Chemical vapour deposition technique is utilized successfully to be manufactured that state
The single-layer graphene of interior first 15 inches, and successfully graphene transparent electrode is applied on electric resistance touch screen, prepare 7
Inch Graphene 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
Material and preparation method thereof, with low cost, to meet the market demand, it is very important.
