Isomer of the conjunctive tissue into the carbon of hexagon lattice.Graphene is with the sp2 hybridized orbits of its unique atomic thickness
Matter, makes it have significant advantage at electric conductivity, heat transfer and intensity aspect.Particularly, Graphene is a kind of with very high
The folded semimetal of zero overlap of electrical conductivity.
The electrical conductivity of Graphene is 1 × 108S/M because its have the electron mobility of 200000cm2/VS with
And the carrier density of 1012/cm2.It is the highest conductance in nature at room temperature.The most frequently used height is listed in table 1 to lead

In any one of embodiment of the present invention." Graphene " one word is used in whole specification, refers to any two-dimensional graphene
Particle.Found by transmission electron microscope image, adjacent graphene film may only have several contact points, graphene particles it
Between contact it is excessively poor, it is very low in interior on a large scale conductance and current density.The graphite Buckie paper reported before the present invention
Highest conductance about 55088S/M, can not show a candle to the electric conductivity of the graphene film of theoretical monoatomic layer.
The present invention has been developed improving the commercial Application technology of the contact between graphite particle, changes so as to provide and have
Enter the composite graphite alkene conductor structure of performance and suitable for a series of practical application.Layer structure of the invention 3 can be one

Individual substrate layer 2 and the alternate structure of graphene layer 1.Then, it is compressed using compression method, graphene layer is changed by compressing
The arrangement of graphene particles in 1.It is this arrangement and compression graphene particles improve graphene particles between contact so that
Improve electric conductivity.Additionally, substrate layer 2 is also used as support frame, play a part of support, so as to further forming layer
Shape structure 3 and constitute electric conductor structure, including traditional electric wire and transmission line structure.
When forming layer structure 3, layer graphene layer 1 is deposited on a surface for substrate layer 2, then by one layer of substrate layer
2 are placed on above graphene layer 1；Demand can be met if a single graphene layer 1, then lamination process terminates, shape
Into the layer structure including layer graphene layer 1；If necessary to multiple graphene layers 1, then second layer graphene layer 1 is deposited on
The surface of second layer substrate layer 2, is circulated, until after setting the quantity of graphene layer 1 of needs, by last layer of substrate layer
2 are placed on the graphene layer 1 of top layer above, and formation includes more than the 2 layers layer structures of graphene layer 13；Finally by stratiform

Obtain more excellent electrical characteristics.
Mechanically deform can provide powerful compression stress and the shearing force perpendicular to compression stress, be applied to the Graphene of wrinkle
Plate/piece can be with the contact of significant improvement graphene particles.The present invention, can using the substrate layer 2 and graphene layer 1 being arranged alternately
A supporting construction is provided using substrate layer 2, facilitates graphene layer 1 to be carried out using known mechanically deform equipment and technique
The treatment of compression, facilitates graphene layer 1 to be compressed, arrange and align along substrate layer 2, further increases graphene layer 1
In graphene particles between contact.
In general, the vertical perpendicular and parallel power in the present invention can also be produced from many mechanically deform methods
Component (compression stress and shearing force).For example, providing the two power (as shown in Figure 3) by roll 4.In the deformation of this machinery
Process, compression stress is produced by the gap less than the material thickness of layer structure 1 between roll 4；Driven by the operation of rolling
The induction force of elongation or the motion of dynamic substrate layer 2, can be used as parallel to the surface of layer structure 3 and perpendicular to the shearing of compression stress
Power.Shearing force can smooth Graphene wrinkle, while improving the arrangement of graphene particles.Shearing force can also improve Graphene
Alignment between particle and graphene particles or substrate layer 2 and contact, therefore, when substrate layer 2 is conductive metallic material, can carry
1 layer of Graphene high and the electric conductivity of the interface between substrate layer 2.Although with roll 4 as an example, other method also can
It is used, for example, extrusion and stretching can also apply perpendicular and parallel force component (compression stress and shearing force) of hanging down.One axial compressive force
These power can be produced, but it is very limited amount of to deform the power parallel to surface for causing by substrate layer 2, and effect is undesirable.
In some embodiments of the invention, graphene particles (films/sheets) are in the higher slice of substrate layer 2.Graphene can be
By coating on substrate layer 2, printing, tape casting, or be layered in other deposition process.The substrate layer 2 can be the paper tinsel of material
Or thin slice.The material of substrate layer can be the materials such as aluminium, copper, silver, gold, platinum, alloy.Although this example uses a metal substrate
Layer is rolled, but any suitable material may serve to make substrate layer 2.In the example for discussing herein, conducting metal quilt
Use, but other metal or metal alloy can also be used as the material of substrate layer 2.However, the material of substrate layer 2 is not necessarily required to
It is metal.Further, since each graphene layer 1 is conductive, the material of substrate layer 2 can be conductive or nonconducting.
Substrate layer 2 can be selected according to the requirement of manufacturing process；For example, the selection of the material of substrate layer 2 may be subject to required
The limitation of mechanical performance；For example select a kind of material suitable for rolling, stretching or extruding.It is alternative or increase substrate layer 2
Selection needs to consider the electrical property of end product and its operating environment rather than material of final conductor product.For example, being applied to
The conductor used in marine environment, corrosion is reduced or eliminated using the substrate layer 2 of polymeric material to try one's best
Risk.The conductor material that the substrate layer 2 of the polymeric material of biocompatibility is used in implantable medical devices.Substrate layer 2
Material selection be likely to consider combine layer structure 3 composite structure product production requirement, the requirement can be based on into
The treatment technology of one step, and final products requirement.With reference to the industrial scale production of the composite structure product of layer structure 3
Can be realized by using known technology, the technology such as such as roll-to-roll printing/coating, or flow casting molding.For example, roll-to-roll print

The rice multiple technologies such as impression system and ink-jet system are realized.Graphene layer 1 can be removed with ultraviolet radiation solvent and its
His organic substance, such as, in coating, printing or deposition process need solvent used etc..Graphene layer 1 can also be subsequent
During be heat-treated, from 50 DEG C to one in suitable temperature, this depends on the material of substrate layer 2 to temperature range, to remove
Remove unwanted material, including moisture, gas or air, and the impurity that can not be removed by ultraviolet radiation.For example, for
Aluminium, temperature can be from 50 DEG C to 550 DEG C, and for silver, it can be from 50 DEG C to 850 DEG C.
A kind of common foil paper a, for example, aluminium foil, can cover at the top or many of single-layer graphene layer as one
The top of top layer graphene layer, forms layer structure in layer graphene layer.Substrate layer positioned at top is optional, layer structure
Can also be using graphene layer as top layer structure.The graphene layer of this structure following process suitable for increasing shielding

In the example being discussed above, a kind of method that laminating method sets up layer structure 3 is described.However, alternative
Method can also be used.Such as, graphene layer 1 can be deposited on multiple substrate layers 2, be then stacked on another top
Formed alternating layer, finally with a common substrate layer 2 as top layer substrate layer 2.
Prepared layer structure 3 is by applying the particle in mechanical forces compress and arrangement graphene layer 1.In an implementation
In example, this is as performed by the substantive mechanically deform of layer structure 3.The power of applying is a kind of compression stress simultaneously in some realities
Apply in example, mechanical force can include the component of (pressure) vertical with layer and parallel (shearing).In one embodiment, layer structure 3
It is to be rolled with the deformation rate of a series of optimization by accurate roller mill, as shown in Figure 3.Layer structure 3 is input to one
In individual roller mill (between 2 rolls 4).Machine is carried out to the layer structure 3 being input into according to the deformation rate set between roller by roll 4
Tool deforms；Make the layer structure 3 of output that the layer structure 3 relative to input is thinning.Apparent such operation of rolling is applicable
In by using hang down perpendicular and parallel force component combination layer structure 3 is compressed and extended, make graphene particles flattening and
Alignment in graphene layer 1.
Such operation of rolling by several passages, using controllable deformation rate, to reach the mesh of final layer structure 3
Mark thickness.For example, deflection can be adjusted between 5% to 40% in one embodiment.Deformation rate depends on the material of substrate layer 2
The original depth of the layer structure 3 of material and substrate layer 2 and the composition of graphene layer 1.In the operation of rolling, by controlling deformation rate
Come avoid " sausage-like " caused by rheology rate different between alternative materials and the material of substrate layer 2 and Graphene or
" wavy " distressed structure.
In the operation of rolling, stress caused by mechanically deform or work hardening can be discharged by interval anneal, while
It is necessary, annealing is to discharge stress caused by mechanically deform or work hardening.In general, annealing temperature selection
At 0.35 to 0.4 times of the Material Melt temperature of substrate layer 2；For example, the annealing temperature of aluminium is 250 DEG C.Annealing steps can be
Carried out in alternate time interval after per a time mechanically deform or between mechanically deform passage；For example, by one
After group iterative deformation.Mechanically deform iteration and the pattern of annealing can change between the embodiment based on the material of substrate layer 2, such as
Compression process and compression degree/mechanically deform (accumulation or iterative deformation rate).Mechanically deform degree depends on the first of layer structure 3
What the final thickness after beginning thickness and finished product rolling was determined.Under normal circumstances, larger mechanically deform amount can cause one
More preferable crystal arrangement orientation and preferably graphene film or flap contact.
In some embodiments of the invention, mechanical deformation processes can be in layer structure 3 further combined with formation one
