"The new material itself is a high-tech, and it is the foundation and precursor of other high-tech. Therefore, the development level of new materials reflects the level of scientific and technological development and comprehensive national strength of a country, and it has important support for national economic development and national defense modernization. And guarantee role." In the interview, Prof. Tang Jianmao, Director of the Consulting Department of the China Society for Materials Research, expressed his excitement in words. "Nothing can be separated from new materials."
â€œNew materials are the foundation and the precursor of all industries, so the breakthrough in the technology of new materials often leads to some epoch-making industrial revolutionsâ€. A person in charge of the Shanghai New Materials Association said, "For example, in the 1960s, the emergence of high-purity silicon semiconductor materials enabled large-scale integrated circuits to be realized, and humans entered the electronic information age."
Some experts predict that the 21st century is a century of new materials, and we can "see the whole leopard" from the competition for rare earth materials.
Due to environmental protection and national strategy, China has reduced rare earth exports year by year since 2006. At present, the total quota is only 30,258 tons. As a result, international rare earth prices have also increased. According to public information, the decline in China's rare earth exports has caused many countries to worry.
"Whether industrial or agricultural needs materials, new materials are a basic and pillar industry, and breakthroughs in materials will likely trigger a new industrial revolution." Professor Tang Jianmao, who has participated in the formulation of the new material strategic positioning plan, said that â€œnew materials are the premise for the revitalization and development of other industries, and materials are needed as support in the production process of any industry.â€
According to relevant ministries and commissions, the sub-planning rules for the new materials industry will be introduced at the end of the year. By then, the specific financial support, tax incentives, product catalogues and other contents in the new materials industry will be clear, and the new materials industry will also develop at a higher starting point.
At the same time, the market size of new global materials has expanded rapidly with the booming manufacturing and high-tech industries. Forecasts show that at the end of 2010, the global market for new materials will exceed 800 billion US dollars. The importance of the state and the expansion of the market scale have injected great vitality into the development of the new materials industry. Earlier, some experts estimated that the domestic market for new materials industry will exceed 130 billion yuan in 2012.
During the "Eleventh Five-Year Plan" period, the implementation of more than 100 industrialization projects has effectively promoted the development of China's new material industry with independent intellectual property rights. A number of high-tech new materials core industries have been formed in electronic information materials, advanced metal materials, battery materials, magnetic materials, new polymer materials, high-performance ceramic materials and composite materials.
Tang Jianmao said that carbon fiber composite materials are new types of lightweight high-strength structural materials, mainly used in high-end fields such as aerospace. Aircraft parts made of carbon fiber composite materials can reduce weight by 20% to 40% compared with aluminum alloys, which can generate great economic benefits in terms of energy saving. "So, in the next 20 to 30 years, it is a new era in the development of aviation carbon fiber composite materials. The use of composite materials on the aircraft will cause revolutionary changes in the entire industrial chain of the aviation industry."
Although the development prospects are very optimistic, China is still full of challenges in the new materials industry.
Tang Jianmao said frankly that compared with other strategic emerging industries, the new materials industry is relatively â€œscatteredâ€ and has many sub-sectors. In China's industrial development, there is a distinct feature: in the same field, there are more repetition levels and redundant construction. However, in the large-scale industries that are truly leading, there are fewer companies with technological advantages, and the new materials industry is facing such a situation as a whole. "This requires national policy guidance, scientific development, resource optimization, and prevention of large amounts of hot money. This is a systematic project."
According to the "Decision", the new materials industry will vigorously develop new functional materials such as rare earth functional materials, high performance membrane materials, special glass, functional ceramics, and semiconductor lighting materials; actively develop advanced structures such as high quality special steel, new alloy materials, and engineering plastics. Materials; improve the development level of high-performance fibers such as carbon fiber, aramid, ultra-high molecular weight polyethylene fiber and their composite materials; carry out research on common basic materials such as nano, superconductivity and intelligence.
