Description
Technical field
The present invention relates to nanometer medical material tech field, more particularly to a kind of nano-PVC medical material and its preparation side
Method.
Background technology
The new medical material formula of nanometer is one and in space, directly sort atom by changing naturally within 100 nanometers
The project of the new nanometer medical material for creating out with molecule.The new medical material of nanometer is modern strength and modern skill with the field
The starting point of art innovation, the discovery of new rule and principle are founded with brand-new theory and give basic science, there is provided new chance,
This can become the new power of important reform in many fields.The new medical material formula of nanometer is tiny due to SAIZU, possesses many peculiar
Performance.Baibich in 1988 etc. has found that magnetoresistive ratio reaches 50 percent for the first time in nanometer Fe/Cr MS,
Compare with general ME and want a big rank, and be negative value, respectively to the same, referred to as GMR.Afterwards also in nanometer system
, find huge ME in tunnel knot and Perovskite structures, membrana granulosa.The inside Perovskite structures were to send out in 1993
It is existing and there is very big ME, be called CMR, find in tunnel knot for TMR.
Nanometer film is divided into membrana granulosa and dense film.Membrana granulosa is that nano-particle sticks together, centre have it is extremely tiny between
The thin film of gap.Dense film refers to that film layer is fine and close but crystallite dimension is nano level thin film.Can be used for：Gas catalysis（Such as vehicle exhaust
Process）Medical material；Filter medical material；High density magnetic recording medical material；Photosensitive medical material；Flat-panel screens is medical
Material；Superconduction medical material etc..
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 medical material science.It is in Germany, big with hamburger
Learn and Mainz university be nanotechnology research center, government provide funds every year 65000000 dollars support micro-systems research.In state
Interior, many scientific research institutions, institution of higher learning also organize scientific research strength, carry out the research work of nanotechnology, and achieve certain
Achievement in research 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.
Nano diamond is made with catalytic pyrolysis method, is completed by the Qian Yitai etc. of Shandong University.They make four with catalytic pyrolysis method
Chlorination carbon and sodium reaction, have prepared diamond nano powder 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 combined medical material market capacitys are up to 545,700,000,000
Dollar, nanofabrication technique market capacity is up to 44,200,000,000 dollars, and the assessment technique market capacity of nanometer medical material is up to
27.2 hundred million dollars.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 nanometer medical material, again this definition was carried out afterwards
Explain.According to the definition of EU Committee, nanometer medical material is that a kind of powdery being made up of basic granules or lumps are natural
Or artificial medical material, one or more three-dimensional dimensions of this basic granules between 1 nanometer to 100 nanometers, and this
The total quantity of basic granules accounts for more than 50% in all total number of particles of whole medical material.
1 nanometer is equal to part per billion meter.On nanoscale, some medical materials have many specific functions.Nanometer
Medical material is used widely in the work and life of people.
The applied research such as nanotechnology fundamental research and the exploitation of new medical material is obtained for quickly development, and
It is widely used in industries such as conventional medical material, medical device, electronic equipment, coating.In terms of industrialized development,
Except nano-powder medical material is in addition to a few countries such as the U.S., Japan, China tentatively realize large-scale production, nano biological
The products such as medical material, nano electron device medical material, nanodoc diagnostic medical material are still in developing the stage.
Up to 22.3 hundred million dollars, annual rate of growth is 14.8% to the new medical material market scale of global nanometer in 2010.A few years from now on, with each
The increasing that state is put into nanotechnology applied research, the new medical material industrialization process of nanometer will greatly speed up, and market scale will
Have and high-volume increase.Several products such as nano-sized iron oxide, nano zine oxide, nano silicon oxide in nano-powder medical material shape
Into certain market scale；The extensive nano ceramics medical material of application of nanopowder, nano-textile medical material, nano modification
The medical materials such as coating are also succeeded in developing, and tentatively realize industrialization production, nano-powder granule medical diagnosiss preparation,
The application of microelectronic is just stepping up from experimental research achievements to product industrialization production direction to shift.
