Nanotechnology and packaging printing (Part 2)

v. proposition and category of nano packaging printing

(I) from printing to nanotechnology

papermaking and printing are breakthroughs and great achievements of great significance in ancient information technology, and an important Prelude to the arrival of the Renaissance era. They are called "inventions that predict the arrival of bourgeois society" by Marx. Qian Xuesen, a famous scientist, believes that "the structures around and below nanometer will be a key point of scientific and Technological Development in the next stage, which will be a technological revolution, which will lead to another industrial revolution in the 21st century". Since its invention, printing has experienced more than 500 years of "lead and fire" and nearly 100 years of "light and electricity", and now it has entered the era of "number and". Twenty years ago, Chinese scientists led the Chinese printing industry to bid farewell to lead and fire, usher in light and electricity, and launched a digital printing system for remote version transmission and color publishing, bid farewell to paper and pen, and ushered in digital and. In the 1990s, high fidelity printing has quietly come to us, and its point is about μ M, which indicates that the printed materials are not far away from the nano level

using nanotechnology to make printing materials or add nano materials to printing materials to make nano ink, nano paper, nano printing machine and other nano printing auxiliary materials can greatly improve the quality of printing materials, or produce printing materials with special functions

two ways to create nanostructures have emerged in the nano world, "top-down method" and "bottom-up method". So far, all kinds of engraving techniques we have discussed belong to the "top-down method". The "bottom-up method" is actually a molecular tectonics, which adopts a process similar to engraving, and all kinds of optical printing belong to this category. Top to bottom nano manufacturing methods, such as electron beam printing, have achieved accuracy close to the atomic level. For quite some time, the top-down method is likely to be the preferred method for building truly complex devices. Scanning probe microscopy can meet the requirements of nano printing in such important aspects as resolution, positioning accuracy and manufacturability. Atomic level printing can be carried out with scanning probe microscopy. It can be determined that nano technology is the result of the great power of printing diffusion thinking

nano production technology, especially the preparation of gold "nano dots", is not a new thing. In Medieval and Victorian churches, various colors can be seen on the multicolored glass windows. Ancient pottery is coated with different colored glazes, which are based on the nano scale performance of materials, which is different from the macro scale performance. In particular, nano gold powder will appear orange, purple, red or dark green according to different scales. In a sense, the first nano technologist was actually a glass technologist in front of the forge in the middle ages, rather than a smart worker in a modern semiconductor factory. Obviously, the glazing workers do not understand why their treatment of gold will make the gold show different colors, but we now know the mystery

the research and development of nanotechnology has formed a new scientific and technological field between chemistry, physics, biology and electronic engineering. It is a science and technology based on many modern advanced science and technology. It is the product of the combination of modern science and technology, which will revolutionize the research and application in the original field and trigger a series of new science and technology, Nanotechnology is integrated into almost all branches of contemporary science and technology. Undoubtedly, nano packaging printing is no exception

(II) nano packaging printing is based on the practice of nano science. Nano is equal to one billionth of a meter, which is about three or four atoms wide. From micron technology to nanotechnology is the inevitable result of scientific development, but it is not a simple extension. In the measurement unit between 1 nm and 100 nm, the mass and structural characteristics of matter have changed from quantity to quality, which must not be complete

(III) theoretical basis of nano packaging printing

nano packaging printing is a new discipline that intersects and integrates nanotechnology and packaging printing science. Its theoretical basis is: 1 Nanotechnology must have two conditions: first, nano size; The second is the new physical properties that are not found in nature. 2. There are three kinds of research fields with the strongest function in nanotechnology: -- nano materials—— Nano devices—— Nano detection and characterization. 3. Nano materials. After ordinary materials are made into nanoscale, there are four unique effects: -- small size effect or volume effect—— Surface effect and interface effect—— Quantum size effect—— Macroscopic quantum tunneling effect. 4. Nanotechnology route and nano manufacturing are the key technologies to realize nano state. There are two ways: top-down and bottom-up. 5. Nano material science and nano processing are the two basic disciplines with the closest relationship between packaging and printing in nano disciplines

(IV) proposition on nano packaging printing

1 Definition of nano packaging and printing: Although there is no accurate definition of nano packaging and printing at present, from the perspective of nano science, nano packaging and printing refers to the nano synthesis, nano addition and nano modification of packaging and printing products using nano materials and nano technology, so that they have nano structure, scale and special functions

2. Nano packaging printing has four elements: nano packaging printing material elements, nano packaging container and printing carrier elements, nano packaging printing technology elements, nano packaging printing information elements

3. Nano packaging and printing materials: refers to the system of nano composite packaging and printing materials made of nano particles or crystals with dispersed phase size of nm and other packaging and printing materials

4. The research objects and tasks of nano packaging and printing are: (1) the content of nano packaging and printing research. Including nano packaging and printing technology (preparation method), nano packaging and printing materials, nano packaging and printing structure, nano packaging and printing machinery, nano packaging and printing testing, nano packaging and printing theory, nano packaging and printing market, etc. (2) Study the movement state and law of nano packaging and printing materials in the logistics process, the law of physical and functional changes of nano packaging and printing materials, and the preparation technology; Study the relationship between nano packaging and printing and multidisciplinary, so as to put forward a new concept of packaging and printing, improve and create new packaging and printing technology, packaging technology and decoration technology, and shorten the process of engineering, industrialization and commercialization of existing packaging and printing enterprises and nano packaging and printing

VI. The goal and Prospect of the industrialization of nano packaging and printing

the share of the packaging and printing industry in the national economy has ranked 14th, with an annual output value of more than 300billion yuan, an annual increase of about 15%, and a sustained and high-speed development ranking first in the world

the focus of nano packaging industry is packaging materials and packaging technology. At present, the research and application of nanotechnology in packaging is still in its infancy. However, nanotechnology is bound to become the "commanding height" in the field of packaging in the world. Everything is done in advance, and nothing is done before it is done. In the past, most of the advanced equipment, materials and technologies in our packaging industry were imported. The emergence of nanotechnology will bring opportunities for China's packaging industry and technological innovation. We must speed up the process of technological innovation and strive to be in the forefront of the world. Nano, will realize my dream of packaging power

the market pays great attention to nanotechnology. The global nanotechnology turnover has exceeded 50billion US dollars/year. Experts also predict that the nanotechnology market capacity will exceed 1440 billion US dollars by 2010, and the nanotechnology industry will give birth to the next richest man in the world. Seeing magic in subtle places, nanotechnology will completely change the current industrial structure and breed huge business opportunities. According to the report "nanotechnology" of Stanford Business information consulting company, the market scale of nano materials in the world is expected to exceed 200billion US dollars by 2010

although the scientific community and the business community have made a lot of efforts, the contact channel between them is not smooth enough, and the understanding of nanotechnology in the business community needs to be gradually improved. After all, nanotechnology is high-tech. industrialization requires mature technology, which should be consistent with the process flow of enterprises. Therefore, a new industry - the average export price of China's non-ferrous metals is 19526.34 yuan/ton, and the nano industry has emerged

in the manufacturing industry, some people call nano particles "industrial monosodium glutamate", because by scattering nano particles into many traditional materials, a series of new functions can be improved or obtained, "the old look changes the new face". This improvement is not necessarily expensive, but it makes the product more competitive in the market. It is not easy to change the original products and manufacturing technology of packaging and printing enterprises with nanotechnology. In fact, as a manufacturing technology, nanotechnology can produce unexpected products with new characteristics and functions. For example, take "chalk and shell" as an example. These two things have the same texture, both of which are calcium carbonate, but when the hardness simultaneously exits the test state, one is brittle, which meets the standard, and the other is very hard, which has completely different properties. From this consideration, it is possible to improve their texture by using the manufacturing process of nanotechnology. Nanotechnology is not only a means to improve the texture, but also an important manufacturing technology, which is also one of the important topics of enterprise development in the future. Almost all the successful enterprises in Kansai region of Japan are related to the research or use of nanotechnology, so for Japanese enterprises, the application of nanotechnology is a very effective means to make differences between enterprises. A scientist in Japan even said, "in the future, enterprises that have nothing to do with nanotechnology are bound to collapse."

in order to make China's packaging industry occupy a place in the industrialization of nanotechnology in the 21st century, considering the frontiers, strategies and fundamentals, we should continue to do a good job in the connection between basic research and applied research and the transformation of achievements, study the modification and technical transformation of traditional packaging and printing materials by nano synthesis and nano addition, expand the application scope of nano materials in packaging and printing, improve the high-tech content, and seize the industrial opportunity, Achieving leapfrog development is a very important work. Obviously, whoever wants to stand at the forefront of the world's most high-tech field in the 21st century should take a step ahead in the field of nanotechnology

1. In China, the modification of nano packaging and printing materials is closer to application. In the field of packaging and printing, breakthroughs have been made in nano ink, nano pigment, nano paper, nano film polymer based nanocomposites (pnmc), nano luminescent materials, nano antibacterial packaging, nano adhesive, nano anti-counterfeiting printing, nano military protective packaging, nano green packaging, nano lithography printing technology, nano magnetic printing, and some have been preliminarily industrialized, The evaluation means of nano materials and nanostructures are basically complete, reaching the international advanced level at the end of the 1990s

2. Therefore, in the next step, we must speed up the combination of introduction, digestion, absorption and innovation, take key demonstration enterprises as a breakthrough, promote the development of nano industry, focus on the construction of a number of promotion demonstration enterprises, introduce a number of new nano technologies and products, and find a number of nanotechnology supporting research units. Engaged in the application research of nanotechnology packaging and printing
