Graphene could give LED industry to bring disruptive change?

Mobile phone charging only a few seconds? Mobile phone screen can be folded and bent...... These may be because graphene has "twenty-first Century magic material" said the launch is possible. Found graphene one, Nobel prize winner Andre Haim described: "graphene for a lot of people like Alice in Wonderland, very magical." A new type of nano materials as the most thin, hard, the strongest thermal conductivity properties of Shi Moxi, known as "black gold", is a new material for the king, the scientists even predicted that graphene will completely change in twenty-first Century, and on the application of graphene extraordinary news also emerge in the history of the thin light bulb it only takes a few seconds to charge mobile phone...... Graphene in the end how amazing, whether to the production and living a "subversive" change, let us approach the graphene beitou! Graphene: the magic of "new material" king of this magical substance is what? China is graphite resources in the country, and it is also one of the graphene research and application development of the most active countries, scientists and industry is focusing on it. Many domestic researchers, companies are already engaged on graphene applications, with the progress of technology, the future will expand the graphene preparation and application of the wave of industrialization in the global scope. Graphene, is separated from the graphite material composed of carbon atoms, only one atom thick two-dimensional crystal. With the graphite pencil core is equivalent to countless layers of graphene stacked together. "It is by far the most thin and high strength material, can be infinite tensile, bending to a great extent without fracture, can also withstand tremendous pressure." Andre Haim said, it also has a thermal conductivity and electrical conductivity of the extraordinary. "Graphene has high conductivity, chemical structure is very stable, is a kind of electrode material for mobile battery, power supply is ideal." Chinese Chinese academician, Academy of Sciences Institute of Metal Research Institute researcher Cheng Huiming said that graphene and electronic components, electronic equipment can be further used in combination, in order to improve the storage rate of electric power storage equipment of the other. Graphene is another peculiar is that the "zero penetration" -- all gas and liquid impermeable. It also makes graphene products are "not inserted into the needle, water poured into". The surprise is far more than that. Graphene has strong adsorption, scientists are studying the filtering device to do with it, for desalination, sewage treatment and other fields; it has very good light transmittance, suitable for transparent electronics materials. The key problem here! Graphene into the LED lighting field chances? In LED lighting field, graphene can do what? The following will lead you a glimpse of what from the angle of patent. After a simple search in the Chinese database, found that the application of graphene in the field of lighting patent applications in China began in 2008, after the application is increasing every year, has accumulated more than 1000 patent applications, of which more than 90% applicants from domestic applicants. Mainly related to H01L and F21S two categories, F21S field of application of the basic domestic applicants, mainly using thermal conductivity of graphene coated with light or heat the surface of the lamp, the applicant is more, mainly to enterprises and individuals to apply for, do not describe this. In the field of H01L, ranked in the top ten of applicants are mainly domestic universities and research institutes, enterprises BOE, IBM and Samsung, the IBM application is mainly in the field of power semiconductor devices, Samsung LED OLED, the application relates to a display device and lighting field. The patent 2-8, a graphene layer is added on the original structure (3, 4, 6, 7, 8), due to a series of advantages of graphene transparent, electrical conductivity and thermal conductivity, after adding can make up for deficiencies, thus achieved remarkable results; or directly to the original material for Shi Moxi materials (patent 5), so as to achieve the effect of the technique of the. With the improved patent mostly, this kind of patent technical difficulty is relatively low, the domestic enterprises in the patent strength is not weak in foreign companies, and long-term OEM, technical staff has accumulated a large amount of relevant experience, more easily combined with the characteristics of new materials, puts forward technical improvement plan. Graphene technology development in the field of lighting applications is still in the growth stage, and the advantage of foreign companies is not obvious, domestic enterprises and research institutions, strengthen investment, is believed to have a chance to catch up with the foreign technology, in the future market to get a space for one person. Graphene from the laboratory into people's daily life "new materials for future demand. Application of new type nano materials such as graphene, hazardous chemicals at the fire can not use water to put out, but if you can use graphene film. The use of graphene materials, the future of the mobile phone may thin to the hotel room card almost." Economic Management Institute of Tsinghua University professor Wei Jie said. Graphene products, with warm physiotherapy, LED high thermal conductivity of graphene composite materials, graphene plates material, graphene electric clothes and more than 20 kinds of graphene products have been launched. At present, is praised as the "Oriental carbon Valley" of the Jiangsu Changzhou has graphene industry technology development and business incubator service platform; Chinese Academy of Sciences Chongqing Green Intelligent Technology Research Institute have successfully created 15 inches of graphene has begun to use mobile phone screen; stone high iron interior material
