January 8, 2012, Jiangnan Graphene Research Institute; Changzhou 2D Carbon Technology Co., Ltd.; Wuxi Lige Optoelectronics Technology Co., Ltd. and Shenzhen Lihe Photoelectric Sensor Technology Co., Ltd. to the industry and news unit in Fuzhou Shengmao Hotel, Changzhou Joint release: The world's first mobile phone with graphene capacitive touch screen developed successfully.
It is reported that the results have been searched by Shanghai Science and Technology Information Research Institute and Xiamen University. The conclusions are as follows: “A total of 174 related literatures were retrieved. At present, Chinese and English have not detected the use of graphene as a transparent conductive electrode to produce a capacitive touch screen. "Graphite transparent electrode as a mobile phone with touch screen, related products are currently in the stage of R&D and concept machine abroad, and there have been no reports of large-scale manufacturing and commercialization." This achievement has broken through the bottleneck of graphene products from the laboratory to the market. It is a milestone in the application research and development and industrialization of graphene materials. Since the separation of monolayer graphene from bulk graphite since 2004, it has attracted great attention from academia and industry with its very unique properties. The pioneers in this field, Dr. Geim and Dr. Novoselov, won the 2010 Nobel Prize in Physics for their work. Due to the excellent characteristics of this new material, and the characteristics of environmental protection, high efficiency, and wide application, many companies like South Korea's Samsung, IBM's world-class companies and industry giants have invested heavily in research and development of graphene, trying to get graphite as early as possible. Industrialization and application of olefins.
Dr. Yu Qingkai, a core team member of Changzhou 2D Carbon Technology Co., Ltd., first published a method for synthesizing graphene films by chemical vapor deposition on copper foil in 2008. Today, this method has become the main method for graphene film synthesis. . Graphene film has good transparent conductive properties, which makes it a hot research and industrialization in the field of transparent electrodes and touch screens. An indispensable material in the working layer of the existing touch screen is ceramic material indium tin oxide. Indium tin oxide is expensive (double the price of silver), large in dosage, brittle, and toxic (comparable to lead toxicity). Graphene is composed of pure carbon. Only one layer of carbon atoms is needed in a touch screen, and the working layer thickness of the indium tin oxide touch screen is at least several hundred times thicker than graphene. Graphene touch screen synthesis is harmless to the environment, requires little resources, and production costs are expected to be much lower than traditional indium tin oxide touch screens as production processes continue to improve.
The Quartet team took the lead in successfully applying graphene film to the touch screen of mobile phones, completed the process debugging of the touch screen module based on graphene film, and successfully produced the prototype of the capacitive touch screen mobile phone and completed the functional test. The four-party cooperation team designed a suitable touch screen sensor circuit pattern and integrated circuit driver for the graphene film, and modified the process line of the existing indium tin oxide touch screen module, and designed a process flow specifically for the transparent electrode of the graphene film. A graphene capacitive touch screen phone with all the basic functions is available. The function detection result indicates that the entire touch area of ​​the capacitive screen sensor can recognize the single-finger and two-finger touches and perform the line drawing action, realize the left and right dragging of the picture single-finger gesture and the zooming and rotating of the two-finger gesture, and the basic functions of the capacitive touch screen have been realized. Compared with the traditional indium tin oxide touch screen, the graphene touch screen not only has the advantages of convenient raw material acquisition, low manufacturing cost, simple preparation process, low carbon and environmental protection, but more importantly, it has excellent flexibility, making it a flexible display. The choice of screen and flexible touch screen. It is expected that flexible devices will be the mainstream of future portable electronic products, and flexible devices will be the focus of competition in the electronics industry.
The realization of this achievement proves once again that China has entered from “Made in China†to “Created in China†and has the ability to occupy the commanding heights of industrialization in certain fields. It also marks the entry of graphene materials into industrialization. At the stage, significant social and economic benefits will be generated in the next few years. The process development of this product has ensured the economics of mass production. It is expected that the mass production in this industry will greatly promote the application development and promotion of graphene, which will bring new opportunities for the development of related industries and regions in China.
Bottle Trap
We all tend to see and choose the most beautiful basins and taps for our bathrooms, but never notice that bottle trap, a basin accessory that does so much more than just making the bathroom look great. Bottle trap connect to basin waste, accumulating used water and other waste and dirt, preventing those foul smells from drainage pipe. It has bottle trap, P trap, or S bend.
