Description
Technical field
The utility model relates to the production unit of Graphene, belongs to field of new.
Background technology
Graphene (Graphene) is a kind of novel material of the individual layer sheet structure be made up of carbon atom, is a kind ofly to form with sp2 hybridized orbital the flat film that hexangle type is honeycomb lattice by carbon atom, only has the two-dimensional material of a carbon atom thickness.All can be described as Graphene within 5 layers under normal circumstances.Graphene is thin, the hardest nano material in known world, and it is almost completely transparent, only absorbs the light of 2.3%; Thermal conductivity is up to 5300W/mK, and higher than carbon nanotube and diamond, under normal temperature, its electronic mobility is more than 15000cm2/Vs, again than CNT (carbon nano-tube) or silicon wafer height, and resistivity only about 10-6 Ω cm, than copper or silver lower, be the material that world resistivity is minimum.Graphene is the material that intensity is maximum in the world up to now, if make according to measuring and calculating Graphene the film (thickness about 100,000 nanometer) that thickness is equivalent to bread and cheese plastic packaging bag thickness, so it can bear the pressure of about two tons of heavy articles, and be unlikely to fracture.
The range of application of Graphene is wide.Ultra-thin according to Graphene, the characteristic of intensity super large, Graphene can be widely used in each field, such as ultralight flak jackets, ultra-thin and ultra-light type aircraft materials etc.According to the electroconductibility of its excellence, it is made also to have huge application potential at microelectronic.Graphene likely can become the substitute of silicon, manufactures superminiature transistor, is used for producing following supercomputer, and the electronic mobility that carbon is higher can make following computer obtain higher speed.Grapheme material or a kind of excellent properties-correcting agent, at new energy field as in ultracapacitor, lithium ion battery, due to its highly conc, high-specific surface area, be applicable to as electrode materials auxiliary agent in addition.
