    Controlled fusion that can bring unlimited clean energy to mankind, small to colorful fluorescent lamps, and etching machines indispensable to the chip manufacturing industry... Plasma technology after decades of development, its magic "magic" is increasingly surprising, but China's plasma industry applications are still lack of fire.
    At the 6th National Conference on Industrial Plasma, which concluded in Suzhou on August 26, Li Jiangang, a member of the Chinese Academy of Engineering, and many other experts believe that China's plasma research has been at the forefront of the world, but the industry lacks scientific understanding of this field, plasma technology to look forward to people's knowledge.
    plasma is the fourth state of matter different from solids, liquids and gases

    . Matter is made up of molecules, which are made up of atoms, which consist of a positively charged nucleus and a negatively charged electron around it. When high energy is used, electrons leave the nucleus, and matter becomes a plasma consisting of a positively charged nucleus and a negatively charged electron.
    Li Jiangang said that in the next 10 to 20 years, with the full development of NIF, ITER and CFETR programs, mankind will begin to explore and fully understand the physics of burning plasma at a new level, which will certainly provide more opportunities to discover new physical phenomena and reveal new physical mechanisms, thus pushing the development of plasma physics to a new height. Strong field laser plasma physics has the potential to produce major scientific discoveries and a large number of new technology applications; Industrial plasma (plasma medicine) will also develop rapidly, resulting in new subject growth points. Relying on a large number of technologies developed by these plasma scientific research, it can provide an important source and guarantee for the next high-tech development of human society.
    According to Professor Zhang Wei, Chairman of the Plasma Science and Technology Committee of the Chinese Society of Aesthetics, seemingly "mystery" plasma is not uncommon, the most common plasma is high-temperature ionized gases, such as arcs, neon and sunlights in the glowing gas, as well as lightning, aurora and so on. Plasma in the semiconductor industry, polymer film, material corrosion prevention, metallurgy, coal chemical industry, industrial waste treatment and other fields have a wide range of applications, the potential market value of nearly 200 billion U.S. dollars per year.
    Meng Yudong, a researcher at the Institute of Plasma Physics of the Chinese Academy of Sciences, told reporters that the interaction between charged particles in plasma is very active, and that the properties can be used to achieve surface changes in various materials. Used in shoe making to avoid chemical contamination from traditional processes and to increase glue viscosity.
    , low-temperature plasma technology is more common in industrial applications, but the application in China is still very limited. For example, in the process of wool dyeing using chlorination process, not only produce waste water pollution, felt shrink effect will be relatively large (resulting in clothing shrinkage), if treated with plasma technology, not only no pollution, but also greatly reduce the felt shrink effect. In addition, in the chip industry, plasma technology has also been quite mature, but most of the current foreign monopoly, including etching machines, plasma washing machines.
    Li Jiangang told reporters that China has made great progress in tokmak and other large scientific devices, cutting-edge basic research fields, or civil low-temperature plasma technology, including magnetically constrained fusion, superconducting proton cancer treatment and other fields have been in the forefront of the world.
    , a large number of Chinese enterprises do not know where to get the relevant plasma technology," Li Jiangang said bluntly. To this end, he put forward three suggestions: First, in research institutes and universities to set up a clear direction of low-temperature plasma key laboratories, improve the theoretical and experimental level; Second, the establishment of a number of enterprises as the main body of plasma engineering technology center, plasma engineering and process technology research; Third, strengthen international cooperation.
