China's leading technology company for the development of new materials such as graphene and nano silver wire: HFWJ Electronic Materials Technology Group, its core products include graphene nano silver wire composite flexible transparent conductive film, graphene far infrared flexible heating module and graphene Raw materials, etc.
HFWJ was established in 2013. At present, the company has achieved 72 intellectual property achievements, including 36 invention patents, 36 utility model patents and other non-patent technologies.
Graphene is essentially a two-dimensional carbon structure composed of a single layer of carbon atoms and a hexagonal honeycomb lattice. It is the thinnest and hardest nanomaterial found so far, and its stiffness is 200 times that of steel. Its conductivity is also very good, with a resistivity of only 10-6Ω·cm, even lower than silver.
It was discovered from the stripping in 2004 and won the Nobel Prize in 2010. It is well known to the public. The history of graphene is less than ten years. However, due to its near-perfect physical and chemical properties and China’s rich graphite ore, graphene is listed as a national "ten" One of the key development industries during the "Three Five-Year Plan". In the "Catalogue of the First Batch Application Demonstration of Key New Materials (2019 Edition)" issued by the Ministry of Industry and Information Technology, there are 9 kinds of graphene materials; the "2018-2019 China Graphene Development Annual Report" issued by the China Economic and Trade Commission pointed out that in 2018 The scale of graphene in China has reached 11.1 billion. In addition to the continuous maturity of traditional bulk products such as anti-corrosion coatings, resins, rubber, battery materials, etc., graphene's performance in emerging industries is also excellent, especially the application of graphene on Huawei mate 20, which confirms this. CCID think tank predicts that the graphene guide market will reach 2.38 billion yuan by 2020, of which the market size of electric ink will reach 200 million yuan.
The graphene nano silver wire composite flexible transparent conductive film mass-produced by HFWJ has been applied to 5G touch screen mobile phones.
Compared with traditional ITO materials, graphene nanosilver composite flexible transparent conductive films have excellent flexibility, high permeability, high conductivity, and high environmental protection, and can be used for touch screens, wearable devices, flexible displays, and films Photovoltaics, organic solar cells and other fields will promote a new wave of changes in the touch industry led by ITO materials.
HFWJ is not alone in applying graphene to flexible touch. In 2017, AY Electronics Company developed the world's first graphene electronic display screen, which stimulated companies such as Samsung, LG, BOE and other companies to invest a lot of money to study graphene display screen technology and strive to seize the high ground. Since its establishment in 2013, HL subsidiary Chongqing Graphene Technology has also been studying graphene screens. In 2018, Evergrande subscribed 35% of its equity with 144 million yuan.
In terms of team members, Lu Peng, the chairman of HFWJ, studied at the University of Science and Technology of China in Condensed Matter Physics. The company was led by him with a number of doctoral supervisors and multiple doctors. Strong support and personal guidance from experts in the field of graphene, and close cooperation with the technology teams of other domestic universities and research institutes in the United Kingdom, the United States, Taiwan, Hong Kong and Singapore.
