The most magical nano packaging printing

Magical nano packaging and printing (Part 1)

nano era and its historical background

the whole historical development of human beings reflects such a clear vein: the pace of human exploration has never stopped, from landing on the moon to landing on Mars, and then traveling in space; From recognizing molecules to observing atoms to capturing electrons. Now, while vigorously flying into space and exploring Mars, human beings quietly go deep into the interior of matter and create a new micro Kingdom among the particles of matter. One day, people will manufacture matter according to their own wishes. Gradually in the future, DuPont will not rule out the possibility of setting up factories in China to uncover the mysteries of the atomic world. In this process, the world has not become smaller, on the contrary, it has become broader. However, in a few short years, any "tiny" thing will appear relatively large, because everyone knows the nano world. Small is even smaller, and our understanding of "how small is small" will be challenged

nanometer (nm) is a unit of length for measuring substances. It is expressed as nm with symbols. Nano is equal to one billionth of a meter, which is about the width of three or four atoms. 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. Nanoscience is a technology based on this small measurement range. Generally speaking, there are two rulers to measure nano materials. One ruler is the scale of nano, and the other ruler is the property of this material that ordinary materials do not have. Generally, substances with certain morphology and nm size are called nano substances. The term expression can be: the English terms are the phrase meaning composed of nano, nanosized, nanoscale, nanostructured, nanometer and any combination of particles, materials, substance, solids, cluster, etc. Chinese terms can derive many meanings, such as: nanoclusters, nanoscale materials, nanoparticles, nanoparticles, nanostructured materials, nanoparticles, nanomaterials, low dimensional materials, and so on. Horst stomier, the Nobel Laureate in physics, declared: "nanotechnology gives us a tool to play with the extremes of nature - atoms and molecules. The possibilities of creating new things become endless." Richard smolley, another Nobel Laureate in physics, simply declared: "nanotechnology is the last frontier for builders."

the broad scope of nanotechnology can include nano material technology, nano processing technology, nano measurement technology, nano application technology, etc. Among them, nano material technology focuses on material production (ultra-fine powder, coating, etc.) and performance testing technology (chemical composition, microstructure, surface morphology, physical, chemical, electrical, magnetic, thermal and optical properties). Nano machining technology includes precision machining technology (energy beam machining, etc.) and scanning probe technology. The research and application of nanotechnology means that people will be able to identify, detect and control substances at the atomic and molecular levels, and study the laws of atomic and molecular behavior and interaction at the nano scale, making human beings usher in an amazing leap in their ability to understand and transform nature, conquer nature and apply nature again

nanotechnology is a multidisciplinary high-tech science and technology rising in the late 1980s and early 1990s, and it still needs further research and development. However, people have expected that nanotechnology will bring a profound and revolutionary change to human society. This revolution is bound to spread to the economic field. The development of nanotechnology is likely to be the last opportunity left to the Chinese who have missed the opportunities of micron technology, information technology and biotechnology in the new century. The plastic industry is also deeply affected by new materials. As a Chinese, we must pay attention to the development of high and new technology in the contemporary world and ignore its impact on mankind, especially in the economic field. Nanotechnology is an energy-saving, low consumption and technology intensive high-tech. Although there is still a long way to go to fully realize its industrialization, the production investment ratio of developing nanotechnology may be higher than that of other high-tech projects. Therefore, nanotechnology may provide a rare historical opportunity for China to catch up with the world economy. Famous American scientists Jonathan Spence and Laurel (Nobel Prize winner) said, "if China miraculously becomes a super advanced country, it depends on nano technology, which can turn the Gobi desert into an oasis."

nanotechnology 1: the most important field of application without experiments for a long time is the manufacture of new functional materials with specific physical and chemical properties. The most typical application is to make nanocomposite particles from two different materials. The European Union published a report as early as 1995, predicting that in the next 20 years, the development of nanotechnology will become the second largest manufacturing industry in the world after chip manufacturing. The application of nanotechnology in the future is far beyond the computer industry

the technological innovation of this century is largely supported by clarifying more microscopic phenomena and the operating technology developed accordingly. However, based on the macro perspective, the pursuit of a more micro world, this traditional technology development will usher in the limit in many fields. If there is no new discovery that is fundamentally different from the tradition, we cannot climb a new level. Nanotechnology is a unique structural technology to discover this effect and artificial. It is precisely by fully mastering and utilizing advanced modern science and technology that people make the prediction and research of nanotechnology possible

in order to discuss the current situation and development trend of international research and development and application of nano materials and technologies, explore the development strategy of nano materials during the Tenth Five Year Plan period, promote the research and application of nano materials and nano technologies in the packaging field, and promote the leapfrog development of China's nano packaging industry, on October 16th, 2001, according to the proposal of the author, Mr. Qiu Chunfu, the leader of China's packaging industry, personally gave instructions, China Packaging Technology Association and China Packaging News jointly held the "First National Nanotechnology packaging application seminar" in Xiamen. Undoubtedly, it is of great significance to formulate the national development goals of nano packaging and meet the challenges of the new century. The theme of the conference is "the application and industrialization of nano technology in the field of packaging". As the review article of "China packaging daily" pointed out, this seminar "spread the 'spark' of nanotechnology in the packaging industry." In the past four years, gratifying results have been achieved

based on the sense of urgency and mission for the development of the packaging industry, the author has been involved in all aspects of nanotechnology theory and application in the special research on the application of nanotechnology packaging and printing for many years. These achievements and experiences are concentrated in more than 2 million words of papers and books. In 2001, "China Packaging News" published an article written by the author, "my opinions on the development of nano packaging industry". In the same year, "on the application of nanotechnology in the field of packaging and printing" won the first prize of national excellent academic achievements. In 2003, "nanotechnology applied in new packaging materials" won the first prize for outstanding scientific and technological academic papers in Western China, and served as a special guest and written exchange paper of the "third Chinese Scientists Forum". In May, 2004, at the request of China Light Industry Press, the author wrote the first monograph on nano packaging printing in China and the world, "nanotechnology and packaging printing", with a total of more than 800000 words and more than 200 photos and atlas, which will be delivered for publication. We would like to invite Shi Wanpeng, President of the China Packaging Federation, and the chief scientist of the nano project to write a preface. We are willing to dedicate this book to the "World Packaging Conference" held in Beijing in April 2004. Recently, the national defense industry press asked the author to write a second monograph entitled "nano modification and application of packaging materials", which was submitted at the end of June this year. These two monographs reveal the research of nanotechnology on transforming traditional packaging and printing from the perspective of application, discuss the framework of establishing nano packaging and printing system, and put forward the goals and ways of industrialization and commercialization of nano packaging

traceability of nano packaging technology

the history of artificial preparation of nano materials can be traced back to at least 1000 years ago, and our ancestors have a history of manufacturing and using nano materials. For example, in ancient China, carbon black made from the smoke of burning candles was used as the raw material of ink and dye for coloring, which was the earliest nano material

due to the limitations of science and technology, the practical ultra-fine materials in the recent century are generally composed of micron level. When ultra-fine materials reach the nano state, they will show new special functions. Nanoscience and technology is the study of special phenomena in the nanometer range

Roy is! The most famous material expert in the late 20th century, specializing in high-tech material research. In 1984, Roy first put forward a new theory of nano materials, creating a new era of nano packaging materials - nano packaging. In 1989, IBM took the lead in "transplanting" xenon atoms with a tunneling scanning microscope (STM) probe to form the logo of IBM, successfully realizing the world's smallest nano scale trademark pattern. Toyota Central Research Institute in Japan has developed nano packaging materials with high and new technology

in 1990, Japan's Seibu Xingchan company first successfully developed the nanocomposite packaging material pa/mt (about 5% montmorillonite and carried out industrial scale production). Soon, nano liquid crystal (nm LCP) composite PET polyester material came out in the United States. Its performance is superior to layered composite packaging materials, and its packaging application is just around the corner

in 1990, epoxy resin was prepared by Japanese synthetic enterprise (mp611620) by synthetic method; Crosslinked NBR (-10%), which has impact resistance and heat resistance, can be used as a high-performance adhesive. In 1991, Amoco company made pa6/ppa (5%) by synthetic method, which can be used as high-strength packaging material. From 1991 to 1993, Japan prepared EPR (30%), i.e. copolymer (60%)/pe, by synthetic method; Talc powder (10%) is used in missile packaging. B2A and 0C use melt blending method to prepare tlcp/pa12, tlcp/peek and tlcppa for military packaging. Tlcp/pl is also produced by the same method, and its biaxially oriented film is used for food packaging

in 1994, ISO began to formulate standards for degradable plastics (packaging) materials. The United States has successfully developed a new pet/lcp nanocomposite packaging material, the trade name of which is vectra In 1995, the EU listed "nano new materials" as the "second largest manufacturing industry". Amoco company of the United States began to industrialize the production of pen polyester new packaging materials In 1996, a Japanese company adopted the direct dispersion method to make PE/ultrafine particles (carbon black) for military packaging and anti electromagnetic packaging. In the same way, PP and other/tio2 (3.5w%) were prepared for UV protection packaging

in foreign countries, many polymer composites related to packaging have been commercialized and industrialized before 1996. Since 1996, the Institute of chemistry of the Chinese Academy of Sciences has invented a one-step method to prepare PA6 nano plastics (nc-pa6) and pet nano plastics (NC PET) by using naturally rich montmorillonite like silicates as inorganic dispersed phases. In 2000, China successfully developed organic nano functional materials - 20 nm active organic polymers, which are expected to be used in high-function special packaging such as conductive packaging and stealth packaging. In fact, China has been studied since the 1980s
