How does graphene industrialization break the ice and set sail

Recently, the new technology industry research company announced that "the seven global trends of graphene in 2017" said: "The future development of graphene is full of variables, and the development of large-scale application is the key." Undoubtedly, large-scale application will accelerate graphene Industrialization broke the ice and set sail. So, what practical paths can achieve this? With this problem, the Science and Technology Daily reporter interviewed senior experts and scholars in the graphene industry.

Path 1: Develop products for the market

The technical path to finding "killer" products is what many graphene companies dream of. For example, the film made of graphene itself is light and transparent, and has excellent heat dissipation performance. How to make it suitable for the people?

A few years ago, watching the mobile phone market prosper, researchers facilitated the use of transparent, transparent and flexible graphene film to make mobile phone touch screen instead of rare earth elements. Feng Guanping, the founder of China's graphene industry and former president of Shenzhen Tsinghua University Research Institute, presented the Nobel Prize-winning Konstantin Novoselov with the discovery of the world's first graphene touch screen mobile phone made in China. They are very rare. However, with the development of technology, the price of touch-screen mobile phones is now only 1/3 of the original. Obviously, graphene films do not have the competitive advantage of mass production in this field. Although it can also be applied to wearable devices such as Huawei and ZTE's smart watches, the demand is small enough to drive the industry.

At the beginning of this year, at the International Consumer Electronics Show (CES) in Las Vegas, the former NBA famous player "Great Shark" O'Neill stared at the graphene functional waistband produced in China, "I want to buy one (I To buy one)", the site is tailor-made, and a pair of graphene physiotherapy knee pads are included in the bag. The reporter learned that the key technology of this product is the heat dissipation performance of graphene film, which is hot in 3 seconds, can supply the body with the required heat, and has far infrared physiotherapy and other functions.

With the increase in the size of smartphones and batteries, the damage caused by overheating or even fire of mobile phone batteries is frequent. On February 10th, the United States Patent and Trademark Office issued a patent application for a heat sink for Apple and mobile devices, in which a portable electronic device that facilitates heat transfer is a heat sink made of graphene.

In an interview with reporters, Feng Guanping pointed out that graphene enterprises must make breakthroughs and must produce products for the urgent needs of users. The idea should be "the application of graphene materials must be available to the people, visible and tangible."

Path 2: upstream and downstream enterprises need to hold a group to warm

In the market, the upstream is the downstream raw material supplier, and the downstream is the upstream customer. The relationship between the two can be described as interdependent and interdependent. At present, most of the graphene is separated from the upper and lower sides. Although the upstream and middle reaches of the industry have been formed, the downstream industrial chain is seriously missing.

This will cause overcapacity in upstream enterprises, and downstream enterprises will not be able to squeeze into the market to test the water. For example, some companies have developed zinc-based heavy-duty anti-corrosion coatings with graphene powder, which has a salt spray resistance time of more than 3,000 hours, and its performance is 5 times higher than that of traditional anti-corrosion coatings, but it can not find customers.

“The successful development of graphene anti-corrosion coatings is only the first step. The biggest problem is market promotion. Few companies are willing to take the risk of trying an unknown product.” The Jiangnan Graphene Research Institute Associate Academy participated in the promotion of this research. Chang, who stayed in the United States, told the reporter.

He explained: "First, coating companies are reluctant to use graphene anticorrosive coatings, because the current high-end coatings market is basically monopolized by international giants such as Haihong and Jordan. Secondly, the coating verification cycle takes 20 years, even though this coating is in The test data in the lab is very good, but graphene as an emerging industry has no conditions or opportunities to prove its performance in practical applications."

In this situation, the upstream and downstream enterprises have a phenomenon of warmth and deep cooperation. The enterprises that produce graphene powder actively help the enterprises that produce anti-corrosion coatings to find customers, and take the lead in applying the products to the wind turbine towers of offshore wind farms as anti-corrosion protection, filling the blanks of using graphene in the field of anti-corrosion at home and abroad, and breaking the tradition. The pattern of long-term monopoly market for wind power coating brands.

Path 3: Accelerating the transformation of the achievements of colleges and universities

Under the craze of global graphene technology development, the number of patent applications in universities and colleges at home and abroad has been considerable in recent years. It is understood that among the top 15 institutions in China, the number of patent applications for graphene technology is almost all universities and research institutes. There are few companies, and there are many scientific research results with market value. Therefore, it is extremely urgent to accelerate the integration of production, study and research in colleges and universities.

The birthplace of graphene The University of Manchester in the United Kingdom has focused on strengthening cooperation with Chinese companies in the past two years, applying breakthrough results in the field of graphene to consumer electronics and mobile communication equipment. James Baker, director of the National Graphene Research Institute of Manda, said: "By working with Huawei, it is expected to apply the research results of graphene to everyday products. This partnership will greatly promote the development of British business and attract foreign investment. ."

At the end of last year, Prof. Sun Litao, an international reviewer of the “Graphite Flagship Project” of the European Union and Associate Dean of the School of Electronic Science and Engineering of Southeast University, led the student team to develop “graphene-based anti-mite masks” for more than four years, mainly through functionalized graphene. The material has a large specific surface area advantage (achieving high-efficiency adsorption), and solves the problem that the existing mask (by electrostatic adsorption) in the market is easy to prevent the failure due to the rapid disappearance of static electricity. Field tests show that the removal rate of PM2.5 is 99.3%, and it has long-acting adsorption and smooth breathing. At present, "graphene-based anti-mite mask" has been put into production.

In a recent interview with reporters, Novoselov pointed out: "The transformation of scientific and technological achievements is very important. The government should support small and medium-sized enterprises, promote their scientific and technological cooperation with universities, and encourage people to use new scientific and technological achievements to start businesses."
