Description
Technical field
The present invention relates to technical field of nano material, more particularly to a kind of nano-PVC and preparation method thereof.
Background technology
Nanometer green wood material formula is one and within 100 nanometers, in space, directly sorts atom by change naturally and divide
The project of the new nano material that son is created out.Nanometer new material and the field are rising for modern strength and modern technologies innovation
Point, the discovery of new rule and principle are founded with brand-new theory and give basic science, there is provided new chance, and this can become perhaps
The multi-field new power of important reform.Nanometer green wood material formula is tiny due to SAIZU, possesses many peculiar performances.1988
Baibich etc. has found that magnetoresistive ratio reaches 50 percent for the first time in nanometer Fe/Cr MS, with general ME ratios
Get up to want a big rank, and be negative value, respectively to the same, referred to as GMR.Afterwards also nanometer system, tunnel knot and
Huge ME is found in Perovskite structures, membrana granulosa.The inside Perovskite structures were to find and have pole in 1993
Big ME, is called CMR, find in tunnel knot for TMR.
Nanotechnology need not be put as a kind of emerging science and technology of most market application potential, its potential importance
Doubt, some developed countries all put into substantial amounts of fund and carry out research work.As colonial has set up research in nanotechnology center, Japan
Portion of culture and education section is classified as nanotechnology as one of four big primary study exploration projects of material science.In Germany, with Universitaet Hamburg and
Mainz university be nanotechnology research center, government provide funds every year 65000000 dollars support micro-systems research.At home, perhaps
Many scientific research institutions, institution of higher learning also organize scientific research strength, carry out the research work of nanotechnology, and achieve certain research into
Really, it is main as follows：
The synthesis of directional nano array carbon nanotube, is completed by Inst. of Physics, CAS Xie Sishen researcher etc..They utilize
Chemical gas-phase method efficiently prepares about 20 nanometers of aperture, the CNT that about 100 microns of length.And thus prepare nanotubes battle array
Row, up to 3 millimeters × 3 millimeters, between CNT, spacing is 100 microns to its area.
The preparation of GaN nanorods, is completed by Tsing-Hua University professor Fan Shoushan etc..They utilize CNT system first
It is standby go out 3 ~ 40 nanometers of diameter, length up to micron dimension semiconductor gallium nitride monodimension nano stick, and it is anti-to propose that CNT is limited
The concept answered.And cooperate with Stanford Univ USA professor Dai Hongjie, realize carbon nano-pipe array on silicon substrate in the world first
The self-organizing growth of row.
Quasi- 1-dimention nano silk and nano-cable, are completed by Inst., of Solid Physics, Chinese Academy of Sciences Zhang Lide researcher etc..
They are using carbon thermal reduction, sol-gel soft chemical method and combine the new techniques such as nano-liquid droplet extension, have synthesized ramet first
Nano wire outsourcing insulator SiO2 nano-cables.
Nano diamond is made with catalytic pyrolysis method, is completed by the Qian Yitai etc. of Shandong University.They use catalytic pyrolysis method
Carbon tetrachloride and sodium reaction are made, diamond nano powder has been prepared with this.
But, compared with the advanced technology of developed countries, we also have very big gap.The German Ministry of Science and Technology was once
Jing made prediction to nanotechnology future market potential：They think that nano structure device market capacity is up to 2000
637500000000 dollars, nano-powder, nano composite ceramic and other nano composite material market capacitys are up to 545,700,000,000 dollars,
Nanofabrication technique market capacity is up to 44,200,000,000 dollars, and it is beautiful that the assessment technique market capacity of nano material is up to 27.2 hundred million
Unit.And the breach of prediction markets may be in information, communication, environment and medicine and other fields.
In a word, nanotechnology is just becoming scientific and technological circle of various countries focus of interest, foretold as Academician Qian Xuesen that
Sample：" the characteristics of structure below ran and nanometer will be next stage development in science and technology, can be a technological revolution, so as to
To be the Industrial Revolution again of 21 century."
On October 19th, 2011, EU Committee passed through the definition to nano material, again this definition was understood afterwards
Release.According to the definition of EU Committee, nano material is that a kind of powdery being made up of basic granules or lumps are natural or artificial
Material, one or more three-dimensional dimensions of this basic granules are between 1 nanometer to 100 nanometers, and this basic granules
Total quantity accounts for more than 50% in all total number of particles of whole material.
1 nanometer is equal to part per billion meter.On nanoscale, some materials have many specific functions.Nano material
It is used widely in the work and life of people.
The applied research such as nanotechnology fundamental research and new material exploitation is obtained for quickly development, and is passing
The industries such as commons material, medical device, electronic equipment, coating are widely used.In terms of industrialized development, except nanometer
Powder body material tentatively realizes outside large-scale production that in a few countries such as the U.S., Japan, China nano meter biomaterial, nanometer are electric
The products such as sub- device material, nanodoc diagnostic materials are still in developing the stage.Global nanometer new material market in 2010
Up to 22.3 hundred million dollars, annual rate of growth is 14.8% to scale.A few years from now on, as various countries add to nanotechnology applied research input
Greatly, nanometer new material industrialization process will greatly speed up, and market scale will have and high-volume increase.Nano-sized carbon in nano-powder material
Several products such as sour calcium, nano zine oxide, nano silicon oxide have formed certain market scale；Application of nanopowder is widely received
The materials such as rice ceramic material, nano-textile material, nanocomposite coatings are also succeeded in developing, and tentatively realize industry metaplasia
Produce, nano-powder granule is just stepping up from experimental research achievements to product industry in the application of medical diagnosiss preparation, microelectronic
Change production mode reform transfer.
