Description
Technical field
The present invention relates to the preparation methods of a kind of lithium and graphene composite film, belong to new function material field.
Background technique
The invention patent relates to the properties of lithium and graphene.
Lithium is most light alkali metal element.Masurium derives from Greek, and original meaning is " stone ".1817 by Sweden's science
Family's A Fuwei acute hearing is in analysis petalite mine Shi Faxian.Main lithium minerals is spodumene, lepidolite, petalite in nature
With peganite etc..Lithium can be found in humans and animals body, soil and mineral water, cocoa power, tobacco leaf, seaweed.Lithium metal is
A kind of argenteous light metal.Lithium metal dissolves in liquefied ammonia.Lithium is different from other alkali metal, at room temperature compared with water reaction
Slowly, but the lithium nitride crystal for generating black can be reacted with nitrogen.The salt of weak acid of lithium is all insoluble in water.In alkali metal chloride
In, only lithium chloride is soluble in organic solvent.The flame of the volatile salts of lithium is in peony, can identify lithium with this.Lithium holds very much
Easily with the chemical combination such as oxygen, nitrogen, sulphur, deoxidier can be used as in metallurgical industry.It is light that lithium can also do lead-containing alloy and beryllium, magnesium, aluminium etc.
The ingredient of matter alloy.Lithium has important use in atomic energy industry.
Graphene (Graphene) is the only one layer of atomic thickness for being stripped out from graphite material, being made of carbon atom
Two dimensional crystal.2004, Univ Manchester UK physicist An Deliegaimu and Constantine's Nuo Woxiao love,
Graphene is isolated in success from graphite, it was demonstrated that therefore it can also obtain jointly Nobel's object in 2010 with individualism, two people
Neo-Confucianism prize.Graphene is both most thin material, and most tough material, and 200 times more taller than best steel of breaking strength.
It has good elasticity again simultaneously, and stretch range can reach the 20% of own dimensions.It is that current nature is most thin, intensity highest
Material, if being made into hammock with one piece 1 square metre of area of graphene, weight itself can bear one less than 1 milligram
One kilogram of cat.Graphene most potential application at present is the substitute as silicon, ultra micro transistor npn npn is manufactured, for producing
Following supercomputer.Replace silicon with graphene, the speed of service of computer processor will be hundreds times fast.In addition, graphite
Alkene is almost fully transparent, the light of absorption 2.3%.On the other hand, it is very fine and close, even the smallest gas atom (helium
Atom) it can not also penetrate.These features make it be highly suitable as the raw material of transparent electron product, and such as transparent touch is shown
Screen, luminescent screen and solar panel.
