Description

A kind of novel graphite alkene flame-retarding 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 resistance Combustion HIPS and preparation method thereof.
Background technology
Graphene (Graphene) is the two dimension of the only one layer of atomic thickness being made up of carbon atom Crystal.2004, Univ Manchester UK physicist An Deliegaimu and Constant Ding Nuowoxiao love, success from SBS, isolate Graphene, it was demonstrated that it can with individualism, Two people obtain Nobel Prize in physics in 2010 the most jointly.
China also has the advantage of uniqueness in Graphene research, from a manufacturing perspective, as stone The SBS of ink alkene raw materials for production, enriches in China's energy storage, cheap.It addition, batch metaplasia Produce and large scale produces the main factor being to hinder Graphene commercial on a large scale.And China is up-to-date Achievement in research the most successfully break through this two hang-up, manufacturing cost is down to 3 from 5000 yuan/gram Unit/gram, solve a volume production difficult problem for this material.Chemical vapour deposition technique is utilized successfully to manufacture Go out the single-layer graphene of domestic first 15 inches, and successfully should by graphene transparent electrode For electric resistance touch screen, 7 inches of Graphene touch screens are prepared.
Graphene is in 2004 in the lab, at that time, and the two of Univ Manchester UK Position scientist An Delie Jim and the Ke Siteyanuowo love that disappears finds that they can be with a kind of non- The simplest method obtains the thinnest SBS thin slice.They shell from highly directional pyrolysis SBS Separate out SBS sheet, then the two sides of thin slice be bonded on a kind of special adhesive tape, tear adhesive tape, Just SBS sheet can be divided into two.The most so operating, then thin slice is 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, system The new method of standby Graphene emerges in an endless stream, through the development of 5 years, it has been found that, by Graphene The field bringing industrialized production into comes within a measurable distance.Therefore, in subsequently three years, An De Lie Gaimu and Constantine's Nuo Woxiao love are sent out in monolayer and bilayer graphene system respectively Having showed the quantum hall effect under integer quantum Hall effect and normal temperature condition, the most therefore they obtain Obtain 2010 annual Nobel Prizes in physics.
Graphene has perfect two dimensional crystal structure, and its lattice is to be surrounded by six carbon atom Hexagon, 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, diamond to be exceeded.At Graphene In, 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 conduction that Graphene is good Property.Graphene is the transparent conductive material of a new generation, in visible region, four layer graphenes saturating Crossing rate suitable with traditional ito thin film, at other wave band, the transmitance of four layer graphenes is far away Higher than ito thin film.
The scientific circles that occur in of Graphene have evoked huge great waves.It has been found that Graphene tool There is unusual electric conductivity, beyond intensity and the fabulous light transmission of iron and steel decades of times, it Appearance be expected to cause at hyundai electronics sciemtifec and technical sphere one take turns revolution.In Graphene, electronic energy Enough extremely efficiently migrate, and traditional quasiconductor and conductor, such as silicon and copper are far from graphite Alkene shows well.Due to electronics and the collision of atom, traditional quasiconductor and the shape of conductor heat Formula releases some energy, and within 2013, general computer chip wastes by this way The electric energy of 72%-81%, Graphene is the most different, and its electron energy will not be depleted, and this makes it It is provided with the good characteristic being not of the common run.
On JIUYUE 2nd, 2015, according to JST (JST) and the northeastern Japan of Japan Atom and molecule material science Gao Deng research institution (AIMR) of university is delivered, and is storing as the next generation Battery and by the lithium-air battery of keen anticipation, possessed the porous material of three-dimensional structure by use Matter Graphene is as anode material, it is thus achieved that higher energy utilization efficiency and more than 100 times Charge-discharge performance.If electric motor car uses this novel battery, then cruise mileage is by from current 200 km increase to 500-600 km.
Due to characteristics such as high conductivity, high intensity, ultra-thins, Graphene is at space flight military industry field Application advantage the most extremely highlight.Not long ago U.S. NASA developed and was applied to space flight neck The graphene sensor in territory, just can well trace element, space flight to earth upper atmosphere Structural defects on device etc. detect.And Graphene ultra light aircraft material etc. is potential should Use the prior effect that also will play, along with social city, technicalization, hommization send out Exhibition, designs the Graphene resistance that a kind of good flame retardation effect, percentage elongation height, oxygen index (OI) height and intensity are high Combustion HIPS and preparation method thereof, to meet the market demand, is very important.
