Nano-cladding technology and its application (below)

3 Application in National Defense Science and Technology

Nanotechnology will have a revolutionary impact on the defense military field. For example: nanoelectronic devices will be used for virtual training systems and real-time contact on the battlefield; nano-detection systems for chemical, biological, and nuclear weapons; new nanomaterials can improve the ability to combat and prevent conventional weapons; and small-scale manufacturing from nano-micro mechanical systems. The robot can complete special reconnaissance and strike missions; the nanosatellite can launch thousands of satellites with a small launch vehicle, compose a satellite network according to different orbits, monitor every corner of the globe, and make the battlefield more transparent. The application of nanomaterials in stealth technology is particularly eye-catching. In radar stealth technology, the preparation of ultra-high frequency electromagnetic wave absorbing materials is the key. Nanomaterials are being developed as a new generation of stealth materials.

4 Nano-ceramic reinforcement and toughening

Advanced ceramic materials play an irreplaceable role in other harsh environments such as high temperature and strong corrosion. However, brittleness is a weakness that ceramic materials cannot overcome. Nano-ceramics have similar metal-like superplasticity as the focus of attention in nanomaterials research. At present, the preparation of nano-ceramic powders is relatively mature, new technologies and new methods are emerging, and the production scale is already available. The preparation methods of nano-ceramic powders mainly include gas phase method, liquid phase method, and high-energy ball milling method. The gas phase method includes an inert gas condensation method, a plasma method, a gas pyrolysis method, an electron beam evaporation method, and the like. The liquid-phase method includes a chemical precipitation method, an alkoxide solution method, a sol-gel method, a hydrothermal method, and the like.

5 Application in Catalysis

The catalyst plays an important role in many fields of chemical engineering. It can control reaction time, increase reaction efficiency and reaction speed. Nanoparticles are used as catalysts in semiconductor photocatalysts, especially in the preparation of organic materials.

6. Application in Coatings

Due to the special surface and structure of nanomaterials, nanomaterials have excellent properties that are difficult to obtain in general materials and show a strong vitality. Surface coating technology is also a hot spot in the world today. Nanomaterials provide a good opportunity for surface coatings, making it possible to functionalize materials. With the help of the traditional coating technology and the addition of nano-materials, nano-composite coating can be obtained, achieving a leap in function and making the traditional coating function modified. The nano-coating has a good application prospect and will bring a new technological revolution to the coating technology, and will also promote the research, development and application of composite materials.

7. Application in other fine chemicals

Fine chemical industry is a huge industrial field with a large number of products and a wide range of uses, and it affects all aspects of human life. The superiority of nanomaterials will undoubtedly bring a gospel to fine chemicals and show its unique strength. Nanomaterials can play an important role in the fields of fine chemicals such as rubber, plastics, and coatings.

Nanoscience is an emerging science that integrates basic and applied sciences, including nanoelectronics, nanomaterials, and nanobiology. The 21st century will be the era of nanotechnology. The application of nanomaterials involves various fields, and has broad application prospects in the fields of mechanics, electronics, optics, magnetism, chemistry and biology. The birth of nano-science and technology will have a profound impact on human society, and it may fundamentally solve many problems faced by mankind, especially major issues such as energy, human health and environmental protection. Nanomaterials will become a shining star in the field of materials science. It will play a decisive role in new materials, energy, and information. With the continuous development of its preparation and modification technologies, nanomaterials will be increasingly widely used in many fields such as fine chemical and pharmaceutical production.
