According to Sci-tech Daily on August 23, due to its high conductivity, high thermal conductivity, high strength and unique two-dimensional structure, graphene has become a hot spot in the research and development of new materials.
On August 21, Dr. Feng Weidong, Vice President of Dongxu Optoelectronics and President of Graphene Business Department of China, told Sci-tech Daily that Manchester University, as the birthplace of graphene and the Global Research Center for graphene, will cooperate with Dongxu Optoelectronics and other companies to develop and commercialize suspended graphene sensing chip products. Promotion of application.
Liu Zhongfan, academician of the Chinese Academy of Sciences and President of the Beijing Graphite Research Institute, said that the application of suspended graphene sensor technology was the first in both academia and industry. The cooperation between the two sides is expected to bring about a new era of marked products for the industrialization and application of graphene globally.
High-end applications of graphene are developing rapidly all over the world. More than 80 countries, such as the United States, the European Union and Japan, have raised the development of graphene materials to a strategic level. The flagship plan for graphene in Europe, the national plan for graphene in Korea and the National Graphene Research Institute in Singapore have been implemented and landed one after another. As the most active area of graphene industrialization in the world, China has made breakthroughs in the application of graphene in coatings, heaters and electrothermal film industries.
Mr. Niu, gmtlight manager, thinks that "the industrialization of graphene as a raw material will push technology to a higher level." He says, "This is not something that any company can do independently, and it requires a high degree of collaboration between research departments and real enterprises.
CVD (Chemical Vapor Deposition) is a method of producing graphene by depositing carbon atoms on a specific substrate. However, it has the disadvantages of high cost of transfer steps and low conductivity. Suspension graphene technology of silicon wafer is to form a suspension cavity array with single layer graphene film on the upper surface through traditional semiconductor technology, and finally form a suspension graphene array on the surface of silicon wafer.
Feng Weidong said that the suspended graphene sensing chip technology has created a unique solution for the "distribution" of CVD graphene films, enabling graphene to better play 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 graphene industry has changed quietly. At the WMC World Mobile Communications Conference in 2019, a series of high-end graphene applications, such as graphene 5G modulator and graphene broadband imaging equipment, appeared. These applications also mean that graphene has gradually become an irreplaceable "super material" from "industrial monosodium glutamate" to "industrial protagonist" and from auxiliary material to main material.
"The application of graphene in the field of Optoelectronics is one of the most exciting things," said Constantine Novosholov, a Nobel Prize winner and professor at the University of Manchester in the United Kingdom. "The cooperation model between Mandarin University and Dongxu Photovoltaic is exciting, which will lead to a large number of potential applications."
