Graphene can give the LED industry to bring disruptive change?

Mobile phone charging only a few seconds? Mobile phone screen can be folded bending...... These may be due to the twenty-first Century magic material, said graphene has become 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? Chinese 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, in fact, is stripped from the graphite material, composed of carbon atoms of only one layer of atomic thickness of two-dimensional crystals. The graphite in the pencil core is equivalent to the innumerable layers of graphene. "It is by far the most thin, the highest strength of the material, can be infinitely stretched, bent to a large extent without fracture, but also can resist a lot of pressure." Andre Haim said, it has unusual thermal conductivity and conductivity. "Graphene has high conductivity, chemical structure is very stable, is a kind of electrode material for mobile battery, power supply is ideal." Chinese Academy of Sciences, Chinese Academy of Sciences Institute of metal research, said Cheng Huiming, graphene and electronic components, electronic devices can be further used in combination, so as to improve the storage rate of other storage devices. 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". It's far more than that. Graphene with super adsorption, scientists are using it to do the filter device for desalination, sewage treatment and other fields; it also has a very good light transmittance, suitable for transparent electronic products as raw materials. The key problem here! Graphene into the LED lighting field chances? In LED lighting field, graphene can do what? Here we will take a look at the patent from the point of view. 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. For example, the application of graphene nano materials, dangerous chemicals in the fire can not be used to destroy the water, but if you can use graphene film. The use of graphene materials, mobile phones may be thin to the hotel room card." Professor, School of economics and management, Tsinghua University, said Wei Jie. Graphene physiotherapy, thermal insulation products, LED with high thermal conductivity graphene composite material, graphene bullet proof material, graphene electric clothing, more than 20 kinds of graphene products were introduced. 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
