纳米材料的发展与应用(国外英文资料) Development and application of nanomaterials Abstract: nano paint on formaldehyde, ammonia and other harmful gases have absorption and elimination function, so that indoor air more fresh. The killing rate of various fungi is more than 99%, and has a long-term anti mildew and anti algae effect. Nano modified interior wall coating is actually an advanced sanitary coating suitable for painting in families, hospitals, hotels and schools. Nano modified exterior wall coatings, using nano materials two yuan together amphiphobic mechanism of lotus leaf, low surface tension, high adhesion, the modification is still in the primary stage of coating for the application of nano materials technology, technology is not mature, the need to explore and improve. However, some properties of coatings have been improved, and the experimental results have proved that the market prospect of nano modified coatings is very good. Keywords: application of nanomaterials The development of nano In 1959, the famous physicist and Nobel prize winner Richard. Feynman predicted that humans can use small machines to produce smaller machines, according to the final realization of the wishes of the human order by atom, manufacturing products, this is the first on the dream of nanotechnology. In 1991, American scientists have successfully synthesized carbon nanotubes, and found that it was only with the quality of the volume of steel 1/6, the intensity is 10 times that of steel, so called super fiber. The nano materials found signs of human to explore material performance has reached a new height. In 1999, the annual output of nano products reached $50 billion. What is nano material? Nano (nm) is a unit of length 1 nm is 10-9 meters (1/1000000000 meters), on the macro nano material, is a very small unit, rather than a human hair, the diameter is 7000-8000nm, the human red blood cell diameter is 3000-5000nm, the diameter of the virus generally tens to hundreds of nano the size of the
