Graphene can bring "disruptive" changes in the LED industry?

How long does it take to recharge your phone? The phone screen can be folded and bent...... These may all be because of "twenty-first Century magic materials" called 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? 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 actually a two-dimensional crystal made out of graphite material and composed of carbon atoms with only one layer of atomic thickness. The graphite used in the pencil core is equivalent to the countless layers of graphene stacked together. "It is by far the thinnest and strongest material in nature. It can be stretched infinitely, bent to a great extent without breaking, and can resist great pressure."." It also has extraordinary thermal conductivity and electrical conductivity, Andre Haim said. "Graphene has high conductivity, chemical structure is very stable, is a kind of electrode material for mobile battery, power supply is ideal." Cheng Huiming, a researcher at the Chinese Academy of Sciences and a researcher at the Institute of Metal Research at the Chinese Academy of Sciences, said graphene could be used in combination with electronic components and electronic devices to increase the storage rate of other storage equipment. 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 more than that. Graphene is extremely absorbent, and scientists are studying the use of it as a filter device for desalination, sewage treatment and other fields, and it has very good light transmission, suitable for transparent electronic products. The key problem here! Graphene into the LED lighting field chances? In LED lighting field, graphene can do what? The following will lead you from the patent 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 nano materials, graphene, fire in dangerous chemicals can not be used to destroy, but if graphene film can be used. Graphene material, mobile phone future may be thin to the hotel room card almost." Tsinghua University School of economics and management professor Wei Jie said. Graphene physiotherapy, thermal insulation products, LED with high thermal conductivity graphene composite, graphene bulletproof materials, graphene electric clothing, more than 20 kinds of graphene products were 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
