On November 28, the 2020 Jiangsu Advanced Carbon Materials Industry Development Conference and China (Changzhou) New Materials Academician Expert Report Meeting was held in Wujin District, Changzhou City. At the meeting, Gan Yong, academician of the Chinese Academy of Engineering and director of the National Advanced Materials Industry Development Expert Advisory Committee, delivered a keynote speech on the "Development Strategy of China's Advanced Materials Industry". He believed that high-end advanced materials are the guarantee to support the country's major strategic needs, and its core technology has made a breakthrough The era is coming.
Gan Yong said that from the current technological development status of major countries in the world and the forecast reports of each country, in the next 10-20 years, a series of disruptive technologies such as artificial intelligence technology, gene editing, Internet of Things technology, and renewable energy technology will develop rapidly. It will have a huge and revolutionary impact on China’s information, energy, medical and transportation fields, and at the same time catalyze the development of quantum materials, biomedical materials, new energy materials, superconducting materials, graphene and two-dimensional materials, high-performance and high-performance materials. There is a huge demand for new materials such as molecules and composite materials and new display materials.
In the report, Gan Yong made a detailed interpretation of graphene and carbon fiber composite materials. Graphene is a new type of nanomaterial with the thinnest, hardest and best electrical and thermal conductivity found so far. It has potential in semiconductors, flexible electronics, sensors, energy storage and conversion, composite materials, biomedicine, environmental protection, and thermal management. The application is extremely wide. "Graphene is a strategic emerging material leading the future high-tech competition. In the future, graphene will replace silicon to make electronic products, which will make electronic products smaller and faster. This will not only promote the progress of the chip industry, but also promote artificial intelligence and cognition. The development of computing." Gan Yong said.
China has mastered the preparation technology and application technology of high-quality graphene core raw materials, and has realized independent research and development of graphene preparation and testing equipment. By 2035, it will fully realize the localization of world-leading graphene preparation and testing equipment, and form a complete graphene material preparation, testing and application equipment industry chain.
"Carbon fiber composite materials are a typical representative of leading the revolution in structural materials. They are new dual-use materials that reflect the country's aerospace manufacturing capabilities and are related to the country's strategic security. The international embargo is strict and independent guarantees must be achieved," Gan Yong said. By 2025, the annual consumption of domestic carbon fiber in aerospace, energy and industrial applications will exceed 18,000 tons; by 2030, the annual consumption of domestic carbon fiber will exceed 50,000 tons, and the output value of carbon fiber and its composite materials will reach 300 billion yuan.
At present, China has established a complete carbon fiber industry system. China has made many major technological breakthroughs in terms of low-cost carbon fiber, domestic carbon fiber application technology and expanded application of typical industries, localization and replacement of carbon fiber, and cutting-edge new technologies of carbon fiber and composite materials. .
Jiangsu is a leading province in China's graphene industry and an important production base for carbon fiber. Changzhou is an important town in Jiangsu's advanced carbon material industry, leading the province and the country in terms of graphene and carbon fiber. Gan Yong expects that in the future, Jiangsu and Changzhou will continue to explore the application of advanced carbon materials such as graphene and carbon fiber in various fields, accelerate the industrialization of scientific and technological achievements, form greater advantages, and enhance China's comprehensive development level.
