Recently, Tianjin Funa Yuanchuang Technology Co., Ltd., a subsidiary of Foxconn, successfully realized the industrialization of the world's first additional carbon nanotube touch screen through the combination of production, study and research with the team of Tsinghua University. At present, it has produced 7million carbon nanotube touch screens, with a monthly production scale of 1.5 million, and has successfully supported Huawei, Coolpad, ZTE, etc

it is understood that the successful industrialization of this technology is the result of the long-term cooperation between the team and Foxconn Group led by fan Shoushan, an academician of the Chinese Academy of Sciences and a professor of Tsinghua University, who only needs to follow simple installation steps. At present, the size of the touch screen they produced has achieved mass production from 1.52 inches to 10 inches. Around this product, 107 authorized patents have been obtained. The equipment is a new material experimental machine with more than 800 sub technologies of electric and chemical patents, combined with software technology and mechanical transmission

according to the introduction, Funa Yuanchuang uses carbon nanotube conductive film to produce touch screens. Compared with traditional indium tin oxide film (ITO), it has four advantages: first, the raw material (market zone) is carbon, without rare metal indium, and the material cost is low; Second, it is flexible, high bending resistance, knock and scratch resistance; Third, it has conductive anisotropy, and can design new principle touch screen to avoid patent litigation of other manufacturers; Fourth, the production process is simple, low energy consumption, low pollution, meeting the requirements of energy conservation and environmental protection

the discovery of carbon nanotubes in the 1990s set off a wave of carbon nanotube research in the world. Due to the complexity of technology and process, most of this technology is still in the laboratory stage. In 2013, the world accelerated the exploration of ways to implement carbon nanotube technology into the industry. In less than half a year, relevant technological breakthroughs continued, including the discovery by the Stanford Research team that carbon nanotubes will become an alternative material for silicon chips, and the world's lightest solid material carbon nanotube fiber material developed by Zhejiang University in China

the Tsinghua University team has been involved in related fields as early as 2001. In April, 2001, Tsinghua University and Nanfeng Chemical Industry Group Co., Ltd. jointly established an industry university research center, which is located in the Beijing Key Laboratory of green reaction engineering and technology of the Department of chemical industry. The two sides have jointly established Tsinghua Nanfeng nano powder industrialization engineering center and jointly developed 15kg/hour mass production technology of carbon nanotubes, becoming the largest carbon nanotube production base in the world at present. In the future, if the development of carbon nanotube industry achieves a breakthrough, it may play a certain role in driving the listed companies of Tsinghua department
