Graphene transparent conductive film, the thickness of mm, free to bend, will be widely used in mobile phone touch screen, etc., smart phone screen soft, flexible LCD panel in the near future may be able to enter the life of people. Participating experts and entrepreneurs also pointed out that although the "age of graphene, the upcoming" but "graphene preparation technology and the high cost", but "bottleneck" restricting its marketization. And the establishment of graphene industry technology innovation alliance, or will break the "bottleneck".
Folding charging fast not only can change the phone
"In the future, these will be widely used in computer, mobile phone, you use the electric blanket, floor heating, etc." Deyang a graphene preparation production enterprise's administrator, in the relevant product display, graphene fever membrane can be used in electric blanket, heating floor heating, airport runway de-icing, greenhouses, graphene thermal conductive silicone used in computer items such as heat dissipation, graphene anticorrosive mother liquor used in ships, containers, municipal engineering and other anti-corrosion engineering, graphene transparent conductive film will be used in mobile phone touch screen, etc.
When we see it has been found that the original industrial material yourself far away, can be so close to his, close, and the feeling of black science and technology can be so good. In display, a piece of transparent thin film has attracted the attention of people.
Guo Anxian said, head of the research and development enterprise, the lack of mm, can be arbitrary curved transparent film is graphene conductive films, will be widely used in mobile phones and tablet touch pad, flexible LCD panel, etc., the "flexible soft screen mobile phone is not a legend, as long as want, you can do it."
A lithium-ion battery production enterprises xiao-ping guo said, general graphene in lithium battery production has been very good experiment results, the charging more than double speed, battery life increased by more than ten times."
Reserves accounted for 40% of the preparation of taking shape
At the end of march, deyang enterprise annual output of 30 tons of graphene graphene preparation powder production line will be put into production, and as early as last year, had been built by the British in suining 10 metric tons of graphene powder production line, the preparation of graphene in sichuan province has begun to take shape.
Deputy commissioner of v-ti Tian Yunhui said that graphene research development in sichuan province have good foundation, deyang is the earliest engaged in large-scale preparation of graphene city, has made a number of major scientific and technological achievements, some achievements in the world leading level, the construction of the province's first large-scale graphene industrial park with a higher level. Other city also actively promote the graphene research and development, such as in suining graphene conductive paste in development, promote the graphene in the industrialization of new energy, electronic information materials application achieved good results.
Tian Yunhui said, bilateral, panzhihua, in our province has rich resources of graphite, can provide sufficient raw materials for graphene industry development, "the province proven graphite ore 80 million tons, accounting for 40% of the national, vigorously develop industrial advantage. With our province new energy, electronic materials, anti-corrosion materials and other fields has a huge demand for graphene material, graphene is the important driving force of industrial development."
Application technology is not mature market space
So, now that graphene can effectively improve the battery charging and life issues, why not large-scale industrialization application? Xiao-ping guo said, mainly cost problem, "graphene before the price is expensive than gold, so called" black gold ", now still to dozens of pieces of hundreds of pieces of a gram. A piece of mobile phone battery, need to add in three or four grams of graphene, the cost of how much more you can imagine.
The reporter understands, although deyang annual output of 30 tons of graphene production line will be put into production, but may be because the market problems to full play. Enterprise manager, told reporters that the downstream enterprises haven't find good application. The suining British a graphene preparation enterprise also expressed the same view, last year, the company has built 10 tons of graphene powder production line, but its full-year sales only 100 kg. And a company in chengdu after samples sent out 30 kg, finally for 3 kg of order, but also from Italy.
"The biggest problem of the development of graphene is application bottlenecks." , it seems to mark chan, a professor at the university of overseas Chinese enterprises have rarely using graphene in practice, because the enterprise core developers don't know the graphene. Market applications of graphene bottleneck, also lies in the variables of graphene itself, "the same preparation methods, the results in different environment is different, so to apply to the product, that's a big difficulty."
Jia-ming li: a global big industry started due pattern
Sichuan graphene application how to decipher "obstruction"? In the afternoon, on March 3, twelfth session of the fourth meeting of the National People's Congress of sichuan delegation for the first time the conference was held in Beijing. Journalist handed the problem of enterprises to the National People's Congress, academician of Chinese academy of sciences, tsinghua university, atomic molecular nano jia-ming li, director of the center for scientific research at hand. Jia-ming li is one of the earliest domestic experts in graphene. "Graphene is a global big industry, from the start, you must have the big pattern, large, not in the corner, more can't behind closed doors, to look to the country and the world." Jia-ming li cut to the chase.
He suggested that, on the basis of established industry technology innovation alliance, to build a top "staff", invited including both in the field of chemical industry, chemical fiber, such as academicians and domestic first-class experts to collision, please ideas, ideas, to think more clearly the downstream direction. At the same time, to one thousand ways to cut down the cost of the product, after the enterprise application truly profitable, will naturally increase application, and this is the market choice, rather than simply rely on propaganda. Get more satisfactory answers to questions for jia-ming li represents the dialed 2004 study of graphene with him distinguished professor of Shanghai jiao tong university, director of the institute, car power battery material Kong Xiangyang call.
"Strict in the sense of graphene is a single layer of carbon six-member ring structure, but at present the tons on industrial production as graphene carbon products to reach such a request." Kong Xiangyang pointed out that the strict said these are carbon product upgrade, like "industrial monosodium glutamate", for use in areas such as conductive agent, the real graphene is still in technical research stage.
Kong Xiangyang said, welcome to the development of graphene industry, but to maintain relatively calm, not follow suit, is not a simple set of concepts, in order to realize standardization, ordering. Must first have a strict definition on graphene, sort of various carbon products, various carbon products of high added value, as long as suitable for the market demand, are worth deep research and development, but not necessarily called graphene.
