As China's seven major strategic emerging industries, the "made in China 2025" key development areas and one of the six major areas of science and technology innovation board, material industry is an important strategic emerging industry in China, and also a key guarantee for the development of manufacturing power and national defense industry. The new material industry has become an important indicator to measure a country's national strength and scientific and technological development level due to its high technology intensive, high R & D investment, high added value of products, strong internationalization and wide application range.
&1.1 definition of new materials&With the rapid development of technology, the definition of new materials was first proposed in the 1990s, and gradually matured and widely used in the early part of this century. In the new material and new material industry definition standard published by the Ministry of science and technology in 2004, new material is defined as: new emerging or developing material with excellent performance that traditional material does not have; material with special performance required by high-tech development; material with special performance due to the use of new technology (process and equipment), It is a kind of material which can obviously improve the performance of the material or produce new functions.
&In the 12th Five Year Plan for the development of new materials industry, the State Council further defines new materials as new materials with excellent performance and special functions, or materials with significantly improved performance and new functions after the improvement of traditional materials. The scope of new materials changes with economic development, scientific and technological progress and industrial upgrading.
&Classification of new materials < br / > 1.2&According to the guide to the development of new materials industry, new materials mainly include: < br / >&Advanced basic materials: nonferrous metal materials, polymer resin and other advanced chemical materials, advanced construction materials, advanced textile materials, etc. < br / > advanced basic materials Key strategic materials: focus on the major needs of the next generation information technology industry and high-end equipment manufacturing industry, with special alloys for high-end equipment such as high-temperature resistant and corrosion-resistant alloys, high-strength light-weight alloys, high-performance separation membrane materials such as reverse osmosis membrane and perfluorinated ion exchange membrane, and high-performance fibers and composites such as high-performance carbon fiber and aramid fiber, Rare earth functional materials such as high-performance permanent magnet, high-efficiency luminescence, high-end catalysis, wide band gap semiconductor materials and new display materials, as well as new energy materials, biomedical materials, etc. < br / >Frontier new materials: graphene, metal and polymer additive manufacturing materials, shape memory alloy, self-healing material, intelligent bionic and metamaterial, liquid metal, new low-temperature superconductor and low-cost high-temperature superconducting material.
