摘要
The nanotechnology is of great siguifieance to the country＇s future economic, social development and national security, and it will bring a revolutionary change to the medicine, manufacturing, materials and information communication and other industries, therefore, in recent years, nano science and technology is greatly favored all over the world especially in developed countries. All the countries （areas） in the world have developed the nanotechnology as the main driver of the technical innovation in the twenty-first century, and have formulated development strategies and plans, to promote and guide their development in nanotechnology, which lead to fiercer and fiercer competition. In this paper, the author mainly introduces the application of nano materials in catalysis, filtration, separation, paint and new fine chemical industry and so on.
