Description

A kind of novel graphite alkene is combined HIPS and preparation method thereof
Technical field
The invention belongs to the preparation field of grapheme material, particularly relate to a kind of novel graphite alkene and be combined HIPS and preparation thereof 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 is from tribasic lead sulfate Isolate 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 Tribasic lead sulfate, enriches in China's energy storage, cheap.It addition, it is to hinder Graphene that mass production and large scale produce Extensive 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 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 three the thinnest alkali formulas by a kind of very simple method Lead sulfate thin slice.They separate tribasic lead sulfate sheet from highly directional pyrolysis tribasic lead sulfate, then by the two of thin slice Face is bonded on a kind of special adhesive tape, tears adhesive tape, just tribasic lead sulfate sheet can be divided into two.The most so operate, Then thin slice is more and more thinner, and finally, they have obtained the thin slice being only made up of one layer of carbon atom, here it is Graphene.After this, The new method preparing Graphene emerged in an endless stream, through the development of 5 years, it has been found that, Graphene is brought into the neck of industrialized production Territory comes within a measurable distance.Therefore, in subsequently three years, An Deliegaimu and Constantine's Nuo Woxiao love are at monolayer and double Being found that the quantum hall effect under integer quantum Hall effect and normal temperature condition in layer graphene system respectively, they are the most therefore Obtain 2010 annual Nobel Prizes in physics.Graphene has perfect two dimensional crystal structure, and its lattice is former by six carbon The hexagon that son surrounds, thickness is an atomic layer.Between carbon atom bonded by σ, combination is sp2 hydridization, these σ keys Impart the extremely excellent mechanical property of Graphene and structural rigidity.The iron and steel that the hardness ratio of Graphene is best is strong 100 times, even Diamond to be exceeded.In Graphene, each carbon atom has the p electronics of a non-bonding, and these p electronics can be in crystal Move freely, and movement velocity is up to the 1/300 of the light velocity, imparts the electric conductivity that Graphene is good.Graphene is of new generation Transparent conductive material, in visible region, the transmitance of four layer graphenes and traditional ito thin film are suitable, at other wave band, four layers The transmitance of Graphene is significantly larger than 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.
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 Fire Graphene effective, that percentage elongation is high, oxygen index (OI) is high and intensity is high and be combined HIPS and preparation method thereof, to meet market need Ask, be very important.
