Description
Technical field
The invention belongs to material with carbon element technical field, particularly relate to process for dispersing and the Graphene composite wood of a kind of Graphene
Material.
Background technology
Graphene (Graphene) is the new material of a kind of monolayer laminated structure being made up of carbon atom.It is a kind of by carbon
Atom is with the flat film that sp2 hybrid orbital composition hexangle type is honeycomb lattice, the two-dimensional material of only one of which carbon atom thickness.
As the two dimensional crystal of a kind of only one layer of atomic thickness being made up of carbon atom, it be enter in application at present the thinnest
Material and the most tough material, fracture strength taller 200 times than steel, also have the most elastic, stretch range can reach certainly
The 20% of body size;Graphene has huge theoretical specific surface area simultaneously, and physicochemical properties are stable, can be at high working voltage
With keep good structural stability under big electric current fast charging and discharging, meanwhile, Graphene also have excellence electric conductivity, can drop
Low internal resistance, improves the cyclical stability of ultracapacitor;And Graphene is if able to manufacture superminiature transistor, it is used for producing
Following supercomputer.Replacing silicon with Graphene, the speed of service of computer processor will hundreds times soon;It addition, graphite
Alkene is almost fully transparent, only absorbs the light of 2.3%.And the finest and close, even the gas atom of minimum (helium atom)
Also cannot penetrate.These features make it be highly suitable as the raw material of transparent electron product, such as transparent touch display screen, send out
Tabula rasa and solar panel.Having above-mentioned many excellent physical chemical property just because of Graphene, it is at energy storage material,
Environmental project, sensing sensitive aspect is widely used, and is referred to as " dark fund " or " king of new material ", and before potential application
Scape is vast, has the most become global focus and study hotspot.
But in actual applications, Graphene there is also many problems and restraining factors, Graphene is just easily reunited
It is restriction Graphene research and a major obstacle of application.There is stronger model ylid bloom action power each other to make due to Graphene
It can not stable dispersion in a solvent, also easily again reunite after dispersion and be difficult to open together.According to reported literature, numerous studies
By the way of adding different types of dispersant or modification, improve the dispersion effect of Graphene, but Graphene at water or
Other liquid solutions are difficult to ensure that dispersed;And use the mode adding dispersant to improve the degree of scatter of Graphene, though
It is so the main method currently solving scattering problem, but which is readily incorporated other impurity, subsequent result is produced impact;Or
Person becomes graphene roll, it is simply that graphene platelet is rolled up, and is formed and a kind of is similar to carbon between a peacekeeping two dimension
The web-like nano-carbon material of nanotube, its edge non-close, footpath spacing easily regulates and controls, and has higher specific surface area etc.;But also
The performance of Graphene can be affected, limit its application, also can increase processing cost.
Therefore, how to find a kind of can the method for dispersed Graphene, solve the problem that Graphene is easily reunited, become
For the major issue that the downstream application field of Graphene production firm and Graphene is urgently to be resolved hurrily.
