Due to its high electrical conductivity, high thermal conductivity, high strength, and unique two-dimensional structure, graphene has become a hotspot in the development of new materials. On August 21st, Dr. Feng Weidong, vice president of HBDX Optoelectronics Tech Group and president of the Graphene Business Unit, accepted an interview with the reporter of Science and Technology Daily. As the birthplace of graphene and the global graphene research center, the University of Manchester in the UK will cooperate with HBDX Optoelectronics, Committed to the development and commercialization of suspended graphene sensor chip products.
Liu Zhongfan, an academician of the Chinese Academy of Sciences and director of the Beijing Graphene Research Institute, said that the application of suspended graphene sensor technology is the first case in both academia and industry. The cooperation between the two parties is expected to bring the iconic products for the new era of global graphene industrial application.
Graphene's high-end applications are developing rapidly worldwide. More than 80 countries such as the United States, the European Union, and Japan have raised the development of graphene materials to strategic heights. The European Graphene Flagship Program, the South Korean National Graphene Program, and the Singapore National Graphene Research Institute have successively implemented and landed. As the most active region in the global development of graphene industrialization, China has achieved zero breakthroughs in graphene applications in industrial fields such as coatings, heaters and electric heating films.
CVD (chemical vapor deposition) method for the production of graphene is a method of producing single-layer graphene by depositing carbon atoms on a specific substrate, but it has the disadvantages of high transfer step cost and low conductivity. Silicon wafer suspended graphene technology uses a traditional semiconductor process to form an array of suspended cavities with a single layer of graphene film on the top surface, and finally forms a suspended graphene array on the surface of the silicon wafer.
Feng Weidong said that the suspended graphene sensor chip technology has created a unique solution for the "distribution" of CVD graphene films, enabling graphene to better exert its electrical and mechanical properties. Suspended graphene sensor chip technology will have broad application prospects in the fields of mechanics, temperature, humidity detection and sensing.
In recent years, the product layout of the graphene industry has quietly changed. At the WMC World Mobile Communications Conference 2019, a series of high-end graphene applications such as graphene 5G modulators and graphene broadband imaging equipment were unveiled. These applications also mean that graphene has changed from "industrial monosodium glutamate" to "industrial protagonist". The transformation from wood to main materials has gradually become an irreplaceable "super material".
"The application of graphene in the field of optoelectronics is one of the most exciting things," said Konstantin Novoslov, a Nobel Prize winner in physics and a professor at the University of Manchester. People are excited, which will lead to a large number of potential application scenarios. "
About HBDX Optoelectronics Tech Group
HBDX Optoelectronics Technology Group was established in 1992 and listed on the Shenzhen Stock Exchange in 1996. It is China's largest domestic manufacturer of liquid crystal glass substrates and the fourth largest manufacturer in the world.
The company started from the optoelectronic display industry and gradually developed into a collection of liquid crystal glass substrates, cover glass, color filters, sapphire glass and other optoelectronic display materials and high-end equipment manufacturing and system integration, new energy vehicle R & D and manufacturing, and graphene industrialization applications. The business is a comprehensive high-tech enterprise, and the vertical layout and horizontal linkage of the industry's upstream and downstream have been continuously deepened, and gradually formed an emerging industrial cluster with comprehensive competitiveness.
The company has been deeply plowing the optoelectronic display industry, breaking the international technology monopoly many times and filling a number of domestic gaps. As of now, the company has more than 20 glass substrate production lines built with G5, G6, and G8.5, basically achieving full coverage of different generations of glass substrates. At the same time, the company's cover glass market share ranks first in China and the top three in the world. .
In the field of high-end equipment manufacturing, Dongxu Optoelectronics is the only company in China that has mastered the glass substrate complete equipment production line technology. It provides high-end customers with high-end smart equipment, semiconductor equipment, and automated production line equipment design, R & D, and manufacturing for the TFT-LCD and OLED flat panel display industries. As one of the high-tech equipment manufacturing enterprises. In line with the coming era of artificial intelligence, the company has entered the field of intelligent robots by merging the Sambo innovation of the leader in the field of commercial service robots, entering the field of robots from a high starting point, grasping the two core elements of intelligent upgrade of artificial intelligence and big data, and accelerating the high-end equipment business. Industrial chain extension and intelligent strategy upgrade.
The new energy automobile industry is a key business segment of the company's forward-looking layout of the green industry. New energy bus sales in 2018 ranked among the top eight in the industry; pioneering use of AI technology, and the creation of the world's first artificial intelligence bus with Shenlan Technology (Shanghai) Co., Ltd .; hydrogen fuel cell bus with years of technology accumulation to protect Zhangjiakou City Public transportation in the district will help the 2022 Green Winter Olympics. At the same time, the company's Shenlong bus is included in the logistic support vehicle supplier list of the Central Military Commission.
Dongxu Optoelectronics is one of the earliest Chinese companies entering the graphene field, and has now developed into a leader in graphene industrial application. The company has built four large-scale application sequence products of graphene-based lithium-ion batteries, graphene energy-saving lighting, graphene thermal management, and graphene anticorrosive coatings, and "killer" high-end application products for suspended graphene sensor chips. This field fills the gap in the industrial application of graphene at home and abroad.
