Nantong, a "photovoltaic gene" company to develop a breakthrough in graphene materials

Jiangsu enterprises have made significant breakthroughs in the application of graphene in the field of apparel fibers. At the appraisal meeting for scientific and technological achievements held at Shanghai on September 27th, "Graphene Normal Temperature Intercalation and Stripping Preparation Technology and Its Applications in Textile Materials", the opinion was expressed by domestic experts like Academician Sun Jinliang of the Chinese Academy of Engineering and Secretary General Li Yichun of the China Graphene Industry Alliance. The above two innovative achievements are outstandingly practical and have reached the international advanced level. The result comes from Nantong Via Graphene Technology Co., Ltd., a new company with “photovoltaic genes”.

China's graphene industry has developed rapidly in recent years. At present, it has formed six major market sectors, including new energy, health, energy conservation and environmental protection, composite materials, graphene raw materials, and graphene equipment. It is engaged in the research, development, production and application of graphene. The number of related companies exceeds 400, accounting for about three quarters of the global graphene business. The China Graphene Industry Alliance predicts that the global graphene application market will form an industry outbreak in 2018 and will grow to 100 billion yuan by 2020.

According to Sha Xiaolin, chairman of Johnson & Johnson Optoelectronics and chief investor of Nantongya, in 2009, when the photovoltaic industry was in the ascendant, he entered the graphene field. In the past seven years, the company has invested a total of more than 20 million yuan, and has been doing preliminary research and development for the industrial chain and market demand. Even if the photovoltaic industry experienced cold winters, it still persists. It is understood that 70% of its investment is for talent. A R&D team consisting of experts from China, the United States, and Germany has been established. It has won one national invention patent, six national invention patents, five international PCT invention patents, and one authoritative scientific journal published by SCI. At present, the company has a relatively complete technical reserve from upstream materials for graphene to downstream applications, and has successfully developed a new series of graphene materials based on composite fibers. Sha Xiaolin introduced that existing investment institutions intend to invest RMB 1 billion to acquire the company.

The new graphene composite fiber developed by Nantong Weiya has graphene nylon fiber, polyester fiber, etc. It has obvious effects in antibacterial, anti-caries, anti-ultraviolet, etc. It also has certain functions in heat resistance, antistatic, anti-cutting and so on. "Single-layer graphene intercalation at room temperature intercalation preparation technology", the cost is only one-tenth of similar foreign products. The company plans to mass-produce graphene functional specialty fibers next year, with a production scale of 10,000 tons. On the other hand, to further optimize the single-layer graphene raw material production technology, continue to maintain the international advanced level. It is reported that the company's annual production of 5 tons of single-layer graphene production line has begun operations, the second production line with an annual production capacity of 100 tons will be put into production in the first quarter of next year.

However, experts also called for the investment in graphene industry to be indispensable and must be aimed at market demand and have its own core competitiveness. Li Yichun, secretary-general of the China Graphene Industry Technology Innovation Strategic Alliance, frankly stated that “the development of graphene must go beyond the misconception of 'conception hype' and not blindly put into production, or work hard on substantive applications”.
