Because the physical properties of graphene unique, electrons can in the faster flow of graphene material surface, and can more quickly combined with copper ions, in other words is the battery charging speed can be greatly improved. The future development of graphene is uncertain, and the development of large-scale applications is key. No doubt large-scale applications will accelerate the industrialization of graphene.
The development of graphene in large scale applications will accelerate the industrialization of graphene
Path 1: develop products for the market
Finding the technological path to "killer" products is something many graphene companies dream of. For example, the thin thin films made of graphene are light and thin and have superior cooling properties. How can they be used by people?
A few years ago, looking at the boom in the mobile phone market, researchers made use of the transparent, transparent and flexible graphene film to make a touch screen for mobile phones instead of rare earth elements. Founder of graphene industry in China, the original research institute, tsinghua university in shenzhen guan-ping feng show made in China the world's first graphene touch screen mobile phone, that was awarded the Nobel Prize to find graphene konstantin carbon are rare. However, with the development of technology, the price of touchscreen phones is now only 1/3 of the original price. Obviously, graphene films do not have the competitive advantage of mass production in this field. Although it can be used in wearable devices such as huawei and zte's smart watches, the demand is small enough to drive industry.
At the beginning of this year in the United States on the international consumer electronics show (CES) in Las Vegas, the famous former NBA player "sharks" shaq staring at the Chinese production of graphene function to protect the waist said, "I want to buy one (a) I'd like to buy", the scene is customized, and will be a pair of graphene therapy knee. The reporter learned that the key technology of this product is the heat dissipation of graphene thin film, 3 seconds is heat, can supply the body need heat, and has the function such as far infrared therapy.
As smartphones and battery sizes increase, the number of injuries caused by overheating or even fire in mobile phone batteries. On February 10, the United States patent and trademark office issued a about apple and patents on mobile devices radiator, which involves is advantageous to the heat transfer of the portable electronic device is composed of graphene radiator at work.
In an interview with reporters, Mr. Feng noted that graphene companies have to make a breakthrough and have to make use of products that are urgently needed by users. The idea should be that "graphene material applications must be used by ordinary people to see and touch".
Route 2: the upstream and downstream enterprises need to huddle for warmth
In the market, upstream is the downstream raw material supplier, downstream is the upstream customer, the relationship is as the shadow of each other, interdependence. However, the current upstream and downstream of graphene are mostly separated, although the upstream and middle reaches of the industry have been formed, but the downstream industrial chain is seriously missing.
This can result in excess capacity of upstream enterprises, and downstream enterprises can't get into the market to test the water. For example, the company has developed the zinc ene heavy anticorrosion coating with graphene powder, which has more than 3,000 hours of salt spray and has more than five times the performance than traditional anticorrosive paint, but can't find customers.
"The success of graphene anticorrosive paint is only the first step, and the biggest problem is marketing, and very few companies are willing to risk an unknown product." Dr Qu yan, associate dean of the jiangnan graphene institute, which was involved in the study, told reporters.
He explained: "first of all, the coatings companies are reluctant to use graphene anticorrosive coatings because the high-end coating market is largely monopolized by international giants such as haihong and jotun. Secondly, coating validation cycle need 20 years, although the paint in the laboratory test data is very good, but I can't conditions of graphene as a new industry or the opportunity to prove its performance in practical application."
In this situation, the upstream and downstream enterprises appear to huddle for warmth, in-depth cooperation phenomenon. Graphene powder production enterprises to actively help in the production of anti-corrosion coatings companies to find customers, take the lead in the product applied to offshore wind farm wind turbines as anti-corrosion protection, tower drum filled in the domestic and foreign application of graphene to blank in the field of anti-corrosion, and break the traditional wind power coating brand long-term monopoly market structure.
Path 3: accelerating the transformation of university hospitals
With the development of global graphene technology, the number of patent applications from colleges and universities in recent years has been considerable. It is understood that in the top 15 institutions of graphene technology patent applications, almost all of them are institutions of higher learning and research institutes. There are few enterprises, and there is no shortage of research achievements of market value. Therefore, it is urgent to accelerate the integration of university-industry research and development in colleges and universities.
Graphene "birthplace" Manchester university pays attention to strengthen the cooperation with Chinese enterprises in the past two years, the breakthrough in the field of graphene is applied to consumer electronics and mobile devices. , director of the national institute of graphene James baker, said: "through the cooperation with the company, is expected to be the application of the research results of graphene in everyday items, this partnership will greatly promote the development of British business and attract foreign investment."
Late last year, the eu international "graphene flagship project" evaluation experts, vice President of the institute of southeast university of electronic science and engineering professor Sun Litao lead the student team lasted more than four years to develop "graphene based haze mask", the main advantages of large specific surface area with the aid of functionalized graphene materials (efficient adsorption), existing in the market face mask (by electrostatic adsorption) easily due to electrostatic quickly disappearing to prevent failure problem of haze. The field test shows that the removal rate of PM2.5 is 99.3%, and it has the characteristics of long-term adsorption and smooth breathing. At present, the "graphene-based anti-haze mask" has been put into production.
Carbon recently when accepting a reporter to interview points out: "the transformation of scientific and technological achievements is very important, the government should support the small and medium-sized enterprises, contribute to their scientific and technological cooperation with the colleges and universities, and to encourage people to start startups using new scientific and technological achievements."
