Description
Technical field
The invention belongs to the preparation field of grapheme material, particularly relate to a kind of novel graphite alkene strengthen halogen-free flameproof PP and
Its preparation method.
Background technology
Graphene (Graphene) is the two dimensional crystal of the only one layer of atomic thickness being made up of carbon atom.2004, English
University of Manchester of state physicist An Deliegaimu and Constantine's Nuo Woxiao love, success divides from nano imvite
Separate out Graphene, it was demonstrated that it can be with individualism, and two people obtain 2010 years Nobel Prizes in physics the most jointly.
China also has the advantage of uniqueness in Graphene research, from a manufacturing perspective, as Graphene raw materials for production
Nano imvite, 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.
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 nanometer by a kind of very simple method and cover
De-soil thin slice.They separate nano imvite sheet from highly directional pyrolysis nano imvite, are then bonded on the two sides of thin slice
On a kind of special adhesive tape, tear adhesive tape, just nano imvite 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 in monolayer and bilayer graphene
Being found that the quantum hall effect under integer quantum Hall effect and normal temperature condition in system respectively, the most therefore they obtain 2010
Annual Nobel Prize in physics.
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, it
Electron 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
Nano imvite, 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.
On JIUYUE 2nd, 2015, according to JST (JST) and the atom and molecule material of northeastern Japan university of Japan
Material science Gao Deng research institution (AIMR) is delivered, as accumulator of future generation by the lithium-air battery of keen anticipation, logical
Cross and use the porous material Graphene possessing three-dimensional structure as anode material, it is thus achieved that higher energy utilization efficiency and 100
Secondary above charge-discharge performance.If electric motor car uses this novel battery, then cruise mileage is by from 200 current km
Increase to 500-600 km.
Due to characteristics such as high conductivity, high intensity, ultra-thins, Graphene is also pole at the application advantage of space flight military industry field
For prominent.Not long ago U.S. NASA developed the graphene sensor being applied to space industry, just can be well high to the earth
Empty atmospheric trace element, spaceborne structural defect etc. detect.And Graphene is at ultra light aircraft material etc.
Also prior effect will be played, along with social city, technicalization, the development of hommization, design one resistance in potential application
