Graphene, the "king of new materials", leads the electronic revolution

graphene is currently known as the material with the highest strength, the best toughness, the lightest weight and the best conductivity. It is also considered to be one of the new technologies that are most likely to be vigorously developed in the future. However, due to the high technical difficulty, it has not been widely used at present. It is reported that following the first application of graphene film in Huawei mate20x, Huawei recently released to prevent data loss caused by forgetting to save the disk due to sudden power failure. The first 5g flat-panel matepadpro5g in China is equipped with ultra thick 3D graphene heat dissipation technology

this technology uses graphene as raw material, and uses multilayer graphene to stack the high-temperature guided hot film, which has the characteristics of good mechanical properties, high thermal conductivity, light weight, thin material, good flexibility and so on

it is worth mentioning that Huawei has just invested in Changzhou fullerene technology, and further includes other amputee step layout graphene technology. The latter's existing products include graphene heat conducting film, graphene heat conducting sheet, graphene foam film, etc. the "graphene liquid cooling" solution used by Huawei and glory is the material provided by fullerene technology

the improvement of heat dissipation performance provides an opportunity for the development of heat conducting materials. The heat dissipation schemes are diversified, mainly including graphite sheet, graphite film, metal backplane, heat conduction gel, liquid cooling technology (soaking plate), etc. in the future, we will consider a variety of ways to combine or develop more feasible directions

in terms of industrialization, graphene occupies a key position in strategic frontier materials. At present, graphene is on the eve of large-scale industrialization, and the industry expects the industrialization and application process of graphene to be significantly accelerated

China plans to achieve the development goal of "forming an industrial scale of 10 billion by 2020 and breaking 100 billion by 2025" for the graphene industry

Because of its special structure, graphene has outstanding mechanical properties, electromagnetic properties, thermal properties, light transmittance and permeability, which makes it a hot spot in material science research and has application prospects in many fields

graphene is the thinnest material (0.34nm) known in the world at present, and it is also the strongest material confirmed in history. Its strength can reach 130gpa. It has excellent elasticity and can be stretched to 120% of its own size

graphene has extremely strong thermal conductivity. The thermal conductivity of single-layer graphene can reach 5000 w/m · K, which is 3 times that of pure diamond and 12 times that of metallic copper at room temperature. Graphene also has excellent light transmittance, with a photon transmittance of 97.4% and a theoretical specific surface area of 2630 M2 · g-1

according to the data of graphene industry alliance, in terms of patent technology sources, the earliest priority patents of graphene in China account for 66.6%, followed by South Korea, the United States and Japan, accounting for 12.3%, 9.7% and 3.1% respectively. Graphene patents from China have been significantly ahead of other countries/regions

graphite must therefore ensure that the oil pump is in a vibration free condition. The upstream of graphene includes resources, equipment and systems such as graphite, while the downstream applications include heat conduction, conductivity, flexible display, ink and paint, and the midstream has two product forms of graphene powder and graphene film

with the gradual rise of graphene applications in lithium batteries, touch screens and other fields, the demand for graphene in the upstream of the industrial chain is increasing. The most concerned issue in the industry has become how to realize the large-scale preparation of graphene raw materials, which is also the bottleneck restricting the development of graphene industry at present

the promotion speed and coverage of domestic policies continue to increase, attracting a large amount of industrial capital to continue to invest in graphene related research and commercial applications. At present, the country has established a number of graphene industrial parks and graphene alliances across the country

Changzhou, Ningbo, Qingdao, Chongqing, Wuxi and other places took the lead in establishing graphene industrial parks, and Jiangsu, Inner Mongolia, Shandong and other places have also established graphene alliances, which is conducive to further integrating upstream and downstream resources, improving the graphene innovation system, promoting the development of graphene industry, and is conducive to national macro-control

at the same time, various excellent graphene enterprises in China are also emerging. Although high-end products are difficult to achieve a large-scale breakthrough in a short time due to cost and technical problems, some low-end products have been commercially produced in some companies

the main products of domestic manufacturers Qingdao Haoxin and tiannai technology include graphene and carbon nanotube conductive agents; The main products of the sixth element are graphene powder and graphene film, Sanshun nano and German nano, and the main products are carbon nanotube conductive agents

the main customers of Qingdao Haoxin are BYD, GuoXuan high tech, Dongguan xintaitong, Jiangxi Anchi, Wuhu Tianyi, etc; Tiannai technology customers include Ningde times and BYD; Secondly, customers who are committed to promoting the utilization of graphene materials from theoretical research to the actual production of six elements include daopeng technology, enwang new materials, Huaqi electronics, etc; The main customers of German nano include Ningde times, Hubei Jinquan, BYD, aerospace power, Ganfeng lithium and other enterprises

since the "12th Five Year Plan" of the new material industry in 2012, the country has gradually begun to promote the industrialization of graphene through various favorable policies, and the recent "13th five year plan" of new materials also takes graphene as a leading industry
