Mass production of spinning grade single-layer graphene oxide
Writer:admin    Released:2019-06-10 11:36:18    Type:【L】【M】【S

The world's first spinning-grade single-layer graphene oxide 10-ton production line, which was transformed and built by the team of professors of Zhejiang University, was successfully tested on the 6th. The International Graphene Product Certification Center issued the world's first product certification for the single-layer graphene oxide produced on the production line and its multi-functional graphene composite fiber.

The International Graphene Product Certification Center is a global independent third-party certification body. It was formally established on January 18, 2018 and is headquartered in the United States. The establishment of the organization was supported by China's graphene industry technology innovation strategic alliance and several international organizations.

“Graphene is the strategic frontier and emerging material industry supported by the state. High-quality single-layer graphene powder raw materials have not been mass-produced, which makes the excellent performance of graphene not fully exerted, which makes it difficult to industrialize. He said that he and the team broke through more than ten scientific and technological engineering problems such as full monolayer reaction, high-efficiency separation and purification, powder redissolution, and mastered the original full-scale mass production technology.

It is understood that the single-layer rate of the spinning-grade single-layer graphene oxide 10-ton production line is more than 99%, which can support diverse downstream applications.

Li Yichun, member of the National New Materials Industry Development Expert Advisory Committee and Secretary General of China Graphene Industry Technology Innovation Strategy Alliance, said that with the stable supply of high-quality graphene raw materials, graphene research and downstream application product development will accelerate into healthy and orderly High-speed development track.

According to Zhejiang Online News, Hangzhou Gaowen Technology Co., Ltd., which was established in 2016, has applied for nearly 200 patents in the field of graphene, of which 80% are invention patents. Professor Gao Chao has a clear plan for the development of the company. He and the R&D team have developed the multi-functional graphene composite fiber based on high-quality single-layer graphene oxide, which has obtained the national invention patent authorization, and has anti-ultraviolet and far-infrared internal heating. Antibacterial, antibacterial, anti-mite and negative ion emission functions are a new type of subversive high-end health fiber, which will gradually play a role in carbon fiber apparel, floor heating, mobile phone cooling components, etc. In the future, it will cooperate with energy companies to develop graphite. A battery of olefinic material.

“Now there are more than 100 customers from all over the world who have cooperated with us and achieved 100% satisfaction.” Professor Gao said that with the stable supply of high-quality graphene raw materials, graphene research and downstream application product development will be With the guarantee, the graphene industry will enter a healthy and orderly high-quality development track.
