Graphene, a word that is not yet known to everyone, is gradually forming a new high-tech industry in Jiangsu - the first domestic production line of graphene transparent conductive film with an annual output of 30,000 square meters was officially put into operation in Changzhou not long ago, the world's first. At the same time, the graphene capacitive touch screen for mobile phones was released, and the graphene industry was slightly exposed in the morning in Jiangsu.
​
In the midsummer season, I walked into Changzhou Jiangnan Graphene Research Institute, which is known as the "Oriental Carbon Valley". The reporter was attracted by various fresh and interesting graphene concept products.
​
"Graphene is one of the thinnest and highest-strength materials ever discovered. Since it was successfully developed in 2004 by Andre Geim of the University of Manchester, who won the Nobel Prize in Physics for it, it has caused huge industrial shocks. Enthusiasm for investment.” Qu Yan, general manager of Changzhou Sixth Element Materials Technology Co., Ltd., said that graphene has very good electrical and thermal conductivity, high mechanical strength and flexibility, and good light transmittance. At present, graphene materials are considered to have broad application prospects in touch control, display, energy storage, electronics, composite materials, solar energy and other fields.
​
How amazing is the graphene material? "The mobile phone touch screen made of graphene is still clear and picturesque under strong sunlight, and the touch response speed is greatly improved. In addition, such a mobile phone screen can also be made into a flexible curved shape, people can wear Wear your mobile phone on your wrist like a watch." Jin Hu, president of Changzhou 2D Carbon Technology Co., Ltd. told reporters that more importantly, indium tin oxide is an indispensable material in the existing electronic touch screen, which has high price, large consumption, Fragile and toxic, the graphene touch screen can be rolled up and put in a bag, which not only has the advantages of convenient acquisition of raw materials, low manufacturing cost, simple preparation process, but also low carbon and environmental protection.
​
Graphene has also performed well in batteries. At present, most smartphones charge more than 2 hours at a time, but it only takes 10 minutes to replace them with graphene batteries, and the battery life is greatly extended, so there is no need to worry about the power of the mobile phone "not lasting for the night".
​
Ni Zhenhua, a professor at the Department of Physics of Southeast University, said that Jiangsu universities and research institutes have achieved remarkable results in graphene research, and they are at the forefront of the country in the application of graphene industrialization. In July 2010, Taizhou established the first professional graphene new material company in China - Taizhou Juna New Energy Co., Ltd., which now has a large scale. In October 2011, Changzhou established the Jiangnan Graphene Research Institute, which is the first industrialization base based on graphene materials and applications in China. It has introduced many high-tech enterprises such as Changzhou Sixth Element.
​
"In the field of graphene research, my country is at the same starting line as developed countries. If we miss this opportunity, after a few years, foreign countries have realized industrialization. If we do it again, we will undoubtedly repeat the old story of leading R&D and lagging industries. "Lv Weiming, executive vice president of the Jiangnan Graphene Research Institute, told reporters.
