From August 29th to 31st, 2017, the Nano Science and Technology Conference was held in Beijing. More than 2,000 representatives from more than 30 countries and regions gathered to discuss the future of nanotechnology such as nano platinum .

In 1974, when Japanese scientist Taniguchi Taniguchi proposed the term "nanotechnology," scientists were not optimistic about their future: although this is a "fantastic scientific tool," it is not expected to be mainstream electronic technology for the next 25 years. Have any effect.

Today, nanotechnology, as one of the most breakthrough strategic frontier technologies, has caused subversive changes in materials, medical care, and the environment. Bai Chunli, president of the Chinese Academy of Sciences, said that a series of data and results show that China has become an important contributor to the progress of nanoscience and technology in the world today. It is a world leader in nanotechnology research and development, and some basic research is at the international advanced level. Nanotechnology application research and results The effectiveness of the conversion has also begun to take shape.

1. The nano revolution is changing the world

Tang Benzhong, a professor at the Hong Kong University of Science and Technology and a member of the Chinese Academy of Sciences, said with excitement: "The nano-light revolution has arrived." In fact, not only nano-optics, but also nano-revolutions in the fields of manufacturing, energy, biology, and measurement.

Bai Chunli, president of the Chinese Academy of Sciences, said that nanoscience is the science of studying the interaction, composition, properties and manufacturing methods of matter at the nanometer scale, from atomic to molecular to submicron scale. It brings together the focus of scientific issues in the modern multidisciplinary field at the nanoscale, promotes multidisciplinary cross-integration, and breeds numerous technological breakthroughs and original innovation opportunities. At the same time, the birth of high technology in nanotechnology will have a huge impact on our production and life.

For example, in manufacturing, nanostructured materials are used in surface coatings or lubricants for machine parts to reduce wear and extend machine life. Alloys with nanostructures are characterized by high strength, durability, and light weight. The ideal material for manufacturing aircraft and aerospace components. In the field of medical health, nanotechnology enables drugs to break through chemical, anatomical and physiological barriers, reach diseased tissues, increase the amount of drug accumulation in the lesions, and reduce damage to healthy tissues. Many cancer-targeted drugs use nanotechnology. Even the cosmetics used by girls, the tennis rackets of sports fans, and the bicycles of outdoor sports enthusiasts have all undergone revolutionary changes due to the application of nanotechnology.

2. China's nanoscience is at the forefront of the international

Bai Chunli still remembers such an episode: More than a decade ago, the domestic media had done a show, and randomly interviewed everyone on the street to understand nanoscience. "I remember that there was an aunt who said that it was a new rice! But now, the application of nanotechnology products has entered the homes of ordinary people." Bai Chunli believes that China's nanoscience is in the process of tracking, parallelism and leading. Towards the forefront of the international arena.

At the meeting, the National Nanoscience Center, the Chinese Academy of Sciences Document Information Center and the Springer Nature Group jointly released the White Paper on China's Nanoscience and Technology Development. These data are very eye-catching: China's nano-thesis output increased from 820 in 1997 to more than 52,000 in 2016. China currently contributes more than one-third of the world's nano research papers, almost twice as many as the US. . The performance of Chinese scientific research institutions is more prominent. The Chinese Academy of Sciences has become the most important high-impact paper production institution in the global nano-field. Tsinghua University, Fudan University, Zhejiang University, University of Science and Technology and Peking University are among the top 1% of the universities. The total output of nano-research papers is also ranked among the top 20 in the world.

As a pioneer in the industry, Shangmeng Technology has been at the leading level at home and abroad in super-hydrophobic surface, super-hydrophilic treatment and special coatings. The main products are household and car air purifiers, nano platinum antibacterial care gel, super hydrophobic oleophobic coating, electric anti-icing coating, antibacterial coating, nano silver sol, nano platinum sol and photovoltaic solar cell surface dustproof and snowproof nano coating Etc. Most of these products have independent intellectual property rights. And to undertake the super-hydrophobic, hydrophobic, self-cleaning surface treatment technology solutions, surface super-hydrophilic technical solutions and product development, surface antibacterial and antibacterial treatment and coating technology development, I hope to go further and further in this field.
