As the thinnest, hardest, and best electrical and thermal conductivity of new nanomaterials discovered by humans, graphene has excellent optical, mechanical, electrical, and thermal effects, and is a smart sensor, flexible display, flexible battery and other devices The ideal material. With the vigorous rise of a new round of technological revolution and industrial transformation, artificial intelligence, intelligent technology, and intelligent industries are rising rapidly, can graphene shine and lead the trend in the era of great intelligence? Recently, the "Graphene+" held in Beijing Experts discussed this in the "Smart" seminar.

　　The era of intelligence spawns 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 networked equipment market will reach 300 billion U.S. dollars. With the maturity of integrated circuits, smart hardware, artificial intelligence, cloud computing, and big data technologies, a trillion U.S. dollars market will be created. This is both an opportunity and a challenge for the graphene industry.

　　Zhongguancun Intelligent Hardware Industry Alliance Secretary-General Dong Yu believes that in recent years, with the development of artificial intelligence, intelligent hardware, sensor interconnection, mobile communications, big data and other technologies, "smart+" is rapidly expanding to In all fields of economy and society, new demands in various fields such as industry, agriculture, energy conservation and environmental protection, commerce and trade, transportation and energy, public security, social undertakings, and urban management have been released and spawned, and the "intelligence+" wave is coming across the board. The new graphene material has good application prospects, "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, graphene photodetectors, etc. have been developed. Huang Beiju, an associate researcher of 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. Through mass production, industrial applications can be fully realized. Graphene detectors and CMOS circuits can also be monolithically integrated. Through this monolithic integration, the corresponding advantages of graphene wide-band optoelectronics and the advantages of silicon in electrical signal amplification and processing can be fully integrated, and it has low cost and high integration. And the advantage of high yield, it has very broad market application prospects in the fields of optical communication and infrared imaging. Especially in the field of infrared imaging, graphene infrared imaging chips are entirely possible to subvert the current infrared imaging market.

　　Many problems need 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. Graphene must be widely used in the existing industry. There are many problems that need to be studied and resolved.

　　 Zhongguancun Graphene Industry Alliance Chairman, Beijing Graphene Research Institute, and Chinese Academy of Sciences Academician Liu Zhongfan said that China’s graphene industrialization process has been at the forefront of the world, leading the vigorous development of the graphene industry, but also I have to admit that there is still a lot of 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. The industry needs to work together to maintain sufficient patience and confidence to create the future graphene industry. "Liu Zhongfan said.

　　As the king of new materials, graphene combines super-strong electrical conductivity, thermal conductivity, strength, and flexibility. It is an ideal material for wearable devices. Wei Di, executive director of the Beijing Graphene Research Institute, pointed out that graphene will have a very broad market for wearable electronic devices in the future. Graphene should maximize its strengths and avoid weaknesses based on its unique properties. At present, there is still a long way to go.

　　Shi Haofei, director of the Microsystem Research Center of Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, believes that there are still many challenges in the commercialization of the graphene industry. For example, the sheet resistance of polycrystalline graphene is not low enough. The adhesion of the bottom is biased, graphene cannot be deposited in situ at low temperatures, and the cost is still high.

&ldquo

　　 Regarding the current application status of graphene industry, experts believe that this has something to do with the positioning of my country's graphene industry. Liu Zhongfan mentioned that the graphene industry in the future will be built on the basis of the application of graphene materials, rather than being used as an additive of the “golden oil” type.

　　Industry experts said that at present, the downstream applications of graphene in the domestic market are mainly concentrated in anti-corrosion coatings, conductive agents for lithium batteries, electric heating films and other products. Graphene is only used as an additive to improve the performance of existing products. In contrast to foreign countries, at the Mobile World Congress in April this year, the European Union’s Graphene Flagship exhibited cutting-edge technologies and products such as graphene super cars, IoT 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, and problems such as preparation and transfer technology, structuring technology, and functional integration have all been addressed to a certain extent. Solve and show great potential. With the continuous advancement of technology, graphene will have a lot to do in the field of smart displays.

　　Zhongguancun Development Group Assistant General Manager Jia Yiwei said that Beijing will focus on the major strategic requirements of building a national science and technology innovation center with global influence, break through a batch of key technologies that are overall, forward-looking and driving, and strengthen The development of technical standards for the graphene industry will foster an internationally competitive R&D and innovation system, accelerate the process of graphene industrialization, and create an innovative graphene industry cluster with global influence.
