Two Russian scientists who studied graphene (graphene) won the Nobel prize for physics. Taiwan Institute of material said that the many units have isolated graphene material, which is using graphene composite materials research, create more applications.
The head of the Institute of materials and chemical research Zesheng Lin said, 2004 scientists have isolated from graphite monolayer graphene, only one atom thick. Carbon atoms are mostly graphite and diamond in nature, but graphite is multilayer, and it is very difficult to separate graphene.
Research results show that the properties of graphene and graphite are greatly different, because there is no interference in electronic graphene layer, so the flow speed fast, so it has electrical and thermal conductivity, heat dissipation and strength characteristics of very good, the future possibility of replacing the existing electronic materials is very big, also contributed to the research efforts of the international electronic chip manufacturers and etc. in.
Lin Zesheng for example, research units are the development of graphene to replace the silicon wafer in IC industry; can also be used in the touch panel of the transparent conductive film, can help to overcome future lighting star - light emitting diode (LED) lighting manufacturers can produce more heat, more LED lighting equipment.
He stressed that the many units in the study of graphene material use, the laboratory has separated graphene, is now trying to and other polymer materials, plastics, rubber and other material combination, to create new materials application.
The Royal Swedish Academy of Sciences praised graphene as "the perfect atomic lattice" because it has great potential for development in computers, household devices and transportation. The breakthrough of these two scientists led to the discovery of graphene, a form of carbon that was touted as a super material for the next generation.
Graphene is one of the thinnest and strongest nanomaterials in the world with a thickness of only one atom. It is almost transparent and capable of conducting and heat transfer. As a result, graphene is promising materials that could replace silicon semiconductors.
