Nano-technology has increasingly become a hot topic of today's science, its scope of application is not limited to cosmetic ingredients, but also directly related to the product packaging. Many global operators have started an important study of nanotechnology, how nanotechnology, what is it? It is estimated that the current annual global market demand for products of nanotechnology has reached hundreds of billions. By 2015, nano-technology goods and services, according to measurements may even be up to 1 trillion U.S. dollars.
"Nano technology" The term generally refers to the control of atomic, molecular and super molecular structure, so that it can create the original molecular properties of the same, but the structure is more complex technologies. 1 nanometer (nm) is equal to one millionth mm or billionth of a meter [1]. When people talk about the structure of less than 100 nm (such as the atomic structure or the atomic aggregate structure), or when it comes to the use of a large-scale structure can not meet chemical or physical effects, people often involved in nanotechnology. Engineers can take advantage of nano-technology to prepare nano-scale fine structure, and use of these structures produce a certain effect. When we look at some of nanoscale materials will be difficult to see some common observed behavior. Nano-particles typically have a larger surface area, each and every of its internal atoms are highly exclusive. These nano-particles can be formed in the metal layer of scratch-resistant nature of the hard outer layer of the metal exterior looks "transparent", and resistant to low temperature, but also look like plastic at high temperatures as soft. The nano-technology surface can be treated with water or anti-dust features, while and a lot of other materials coming together and may even become "explosive" material. Therefore, it can be said of nanotechnology can be infinitely small to penetrate any substance in the world.
Some 35 countries around the world have joined the "nano" innovation competition [2]. A year for nano-science and nano-technology, public or private research project budget can reach 90 billion U.S. dollars.
Eno International, Inc. Martin. Bureau of the Nick stressed that the paper is a kind of easy to bend, applications, ranging from a variety of materials made of composite material. For the nano-technological advances, the paper is undoubtedly an ideal choice, but it is strange that the paper industry (paper, cardboard and special purpose paper) rarely involved in nano-equation.
However, the use of nanotechnology, the paper there are a considerable number of advantages:
Coating thinner, smoother, more resilient, and non-toxic;
Paper surface is more smooth, so that printing better, you can also opt for nano-ink printing;
The surface of paper whiteness and brightness higher;
If the paper is rich in minerals, can enhance the properties of minerals and reduce the use of fiber;
Paper and paperboard grades higher quality, lighter;
"Smart" document (RFID) technology;
Paper products to reduce the demand for raw materials at the same time, paper, biodegradable and easier recycling;
Nano-filtration technology to help clean production waste water.
However, the part of the paper industry chemists and engineers who have studied cutting-edge nanotechnology. Has now been observed in nano-scale changes in the pore structure, which may be optical and printing industry has brought significant changes. In addition, nanotechnology has also been in such a light metal such as aluminum surface processing demonstrated its superiority. For example, with "sol - gel" nano technology for light-metal surface layer of chromium plating can eliminate this substance contained toxic substances. In fact, the nano-particles containing metal and metal oxide in the dry process has already begun to form gel (liquid form of paint-like). The material is heated to 160 , there will be a layer of paint solvent evaporation, while the nano-particles will be bound in a stable polymer network.
Claire Garnier in her article, "Alchemy of nanotechnology," pointed out, the Dennis and Guernalec QuertechIngenierie was established in 2005, the company, using nano-technology, making the "rigid than aluminum,", and therefore achieved The international community recognized the patent. Another embodiment example of the impact of nanotechnology from the glass industry, the Canadian manufacturer of safety glass Prelco proposed a protective hydrophobic coatings. We know that water can be attached to the glass surface because of the so-called molecular "surface tension." The use of the patent protection layer is called "nano-fusion", the water molecules no longer directly contact with the glass. The physical properties of water droplets coated beads able to spin-off from the glass surface. The main advantages of this technology are: waterproof and anti-oil, good anti-scratch performance, prevents dust and stains to prevent the hand-prints, antibacterial, effectively increase the glass surface gloss (increased by 20%), and to make the glass surface more smooth (the smoothness increased by 30%).
In the plastics field, the latest example of a hydrophilic thin film nano-imprint invention. The researchers designed a nano-structured mold used in a general hydrophobic plastic film on the embossing, the use of nano-structures to increase its hydrophilicity. As long as gently a bomb, will be able to drop off from the film surface. Forming technology can transform the surface properties of the material, whether such material is hydrophilic or hydrophobic.
Some packaging makers are actively preparing the introduction in 2011 of nanotechnology products. These "nano-packaging" is only involved in the production process it (including raw materials, components such as production), or an outright product will be packaged into a nano-packaging? Actually involved in the field of nanotechnology is very broad, we are now in pilot phase In fact, in the "capture the risk." And this topic there is a problem --- Behind packaging manufacturers want their most valued two groups (customers and consumers) to bring about? However, when we see nanotechnology into mass production process which may From the long-term interest to reduce production costs, but it can also lead to the production companies competing interests, we must know that this is not the main purpose of nanotechnology research. I am an expert from China Textile and Leather, usually analyzes all kind of industries situation, such as immune system booster , programmable hearing aids.
