Can graphene intelligence shine?

As a new type of nanomaterial with the thinnest, hardest, and best electrical and thermal conductivity found by humans, graphene has excellent optical, mechanical, electrical, and thermal effects, and is ideal for smart sensors, flexible displays, flexible batteries and other devices. material. With the new round of scientific and technological revolution and industrial transformation booming, artificial intelligence, intelligent technology, intelligent industry is rising rapidly, graphene can shine in the era of big intelligence, leading the trend? Recently, in Beijing held "graphene intelligence" seminar, experts discussed this.

The age of intelligence creates opportunities

With the continuous development and progress of the Internet of Things technology, the "big intelligence era" will have a huge impact on the future manufacturing industry. According to forecasts, by 2020, the global networking equipment market will reach $300 billion billion. With the maturity of technologies such as integrated circuits, intelligent hardware, artificial intelligence, cloud computing and big data, a trillion-dollar market will be created. This is both an opportunity and a challenge for the graphene industry.

Dong Yu, Secretary General of Zhongguancun intelligent hardware industry alliance, believes that in recent years, with the development of artificial intelligence, intelligent hardware, sensor interconnection, mobile communication, big data and other technologies, "intelligence" is rapidly expanding to various fields of economy and society, releasing and promoting new demands in various fields such as industry, agriculture, energy conservation and environmental protection, trade circulation, transportation and energy, public security, social undertakings, urban management, etc, the "smart" wave is coming. The new graphene material has a good application prospect, and "graphene intelligence" will bring a new industrial revolution and open up a huge market space.

According to reports, graphene has made a series of new progress in information electronic devices, and new devices such as graphene field effect transistors (GFET), graphene electro-optic modulators, and graphene photodetectors have been developed. Huang Beiju, an associate researcher at the Institute of Semiconductors of the Chinese Academy of Sciences, said that in terms of graphene optoelectronic devices, the current performance of graphene detectors is close to the commercial level, and industrial applications can be fully realized through mass production. The graphene detector and the CMOS circuit can also be monolithically integrated. Through this monolithic integration, the corresponding advantages of graphene wide-band photoelectricity and the advantages of silicon in electrical signal amplification processing can be fully integrated, and it has the advantages of low cost, high integration and high yield, and has a very broad market application prospect in the field of optical communication and infrared imaging. Especially in the field of infrared imaging, graphene infrared imaging chip is entirely possible to subvert the current infrared imaging market.

many problems to be solved

The reporter learned that graphene, as a new type of material, has great application potential, but the current mainstream display technology has formed a relatively complete and mature industrial chain. If graphene wants to be widely used in the existing industry, There are many problems that need to be studied and solved.

Liu Zhongfan, chairman of Zhongguancun graphene industry alliance, President of Beijing graphene Research Institute and academician of Chinese Academy of Sciences, said that at present, China's graphene industrialization process has been in the forefront of the world, leading the vigorous development of graphene industry. However, it has to be admitted that there is still great room for improvement in domestic graphene technology research and development and industrialization. "Today's graphene material itself is not enough to support the future graphene industry. It requires the industry to work together and maintain enough patience and confidence to create the future graphene industry." Liu Zhongfan said.

As the king of new materials, graphene is an ideal material for wearable devices because of its superior electrical conductivity, thermal conductivity, strength and flexibility. Wei Di, executive director of the Beijing Graphene Research Institute, pointed out that the market for graphene in wearable electronic devices will be very broad in the future. Graphene should be based on its unique properties, and there is still a long way to go.

Shi Haofei, director of the Microsystem Research Center of Chongqing Institute of Green Intelligent Technology, Chinese Academy of Sciences, believes that in the process of commercialization of graphene industry, there are still many challenges, such as the sheet resistance of polycrystalline graphene is not low enough, the adhesion deviation between graphene and substrate, graphene can not be deposited in situ at low temperature, and the cost is still high.

Be a "trump card", not a "golden oil"

For the current application status of graphene industry, experts believe that this is related to the positioning of graphene industry in China. Liu Zhongfan mentioned that the future graphene industry will be based on the "trump card" application of graphene materials, rather than as a "panacea" additive.

Industry experts said that at present, the downstream application fields of graphene in the domestic market are mainly concentrated in anti-corrosion coatings, lithium battery conductive agents, electric heating films and other products. Graphene is only used as an additive to improve the performance of existing products. On the other hand, at the World Mobile Communications Conference in April this year, the EU Graphene Flagship exhibited cutting-edge technologies and products such as graphene super cars, Internet of Things sensors, wearable devices and health management, data communications, energy technology, and composite materials.

Shi Haofei mentioned that the preparation and application of graphene transparent conductive film has made great progress in recent years, such as preparation and transfer technology, structural technology, functional integration and other issues have been solved to a certain extent, showing a good potential. With the continuous progress of technology, graphene will have a bright future in the field of intelligent display.

Jia Yiwei, assistant general manager of Zhongguancun Development Group, said that Beijing will closely focus on the major strategic requirements of building a national science and technology innovation center with global influence, break through a number of key technologies with overall, forward-looking and driving characteristics, strengthen the development of graphene industry technical standards, cultivate an internationally competitive R & D and innovation system, and accelerate the process of graphene industrialization, To create an innovative graphene industry cluster with global influence.
