Description
Technical field
The present invention relates to a kind of technical field of material, and in particular to a kind of graphene metal heat-conducting composite sheet
Preparation method.
Background technique
As electronic equipment is towards the development of highly integrated, high performance, micromation and functionalization, to heat conduction and heat radiation
Demand is also higher and higher, and it is more next that there are thermal-conductive polymer matrix composites the characteristics such as lightweight, high-strength, corrosion-resistant, easy processing to cause
The concern of more researchers.The value of the research of novel heat-conducting material becomes increasingly to highlight, due to most of electronics
Material can generate vibration when in use and discharge heat, if cannot timely exclude heat, will seriously affect electronics member device
The service life of part, although and traditional metal and inorganic material has good heating conduction, it is big to show weight, mechanical
Performance is poor, and manufacturing procedure is cumbersome cannot to serve as such materials'use, and engineering plastics mechanical performance is excellent and easily molded processing, but
It is that engineering plastics thermal conductivity itself is very poor, needs modified just with preferable conductive force.
Currently, graphene, as conductive filler material of new generation, graphene is a kind of ultralight, ultra-thin, superpower and super large ratio
The quasi- two-dimensional material of surface area, surface density about 0.77mg/m2, the thickness of single-layer graphene about 0.34nm, the toughness pole of graphene
Good, elasticity modulus 1.0TPa, microstrength is more than 100 times of traditional steel up to 30GPa, and theoretical specific surface area is
2630m2/ g, and there is very high conductive, heating conduction, if resistivity is 2 × 10-6Ω .cm, electron mobility is up to 2
×105cm2/ V.S, horizontal thermal conductivity is about 5 × 10 at room temperature3W/m.K.Meanwhile graphene has high thermal stability, changes
Learn stability and excellent permeability resistance and abrasion resistance.Therefore, graphene is in mechanics, electronics, optics, calorifics and new
The energy etc. has been owned by broad application prospect in each field, has attracted the extensive concern of people especially as heat sink material.
It is reported that adding graphene in right amount in metal material, its heat dissipation performance, graphene/gold can be effectively improved
There are mainly three types of the synthetic methods for belonging to composite heat dissipation material: 1, graphene coated thermal dispersant coatings on metallic matrix；2, metal powder
Method；3, refining method etc. altogether is melted.But since graphene is to be easy the characteristics of reuniting, occurs graphite in composite material in above-mentioned prepare
The problems such as alkene dispersion is unevenly and trend is inconsistent, so as to cause the heat dissipation effect for reducing graphene composite material.In addition,
In a kind of method often using organic coating come be bonded between graphene and metal base surface, and general organic coating is led
Hot coefficient is all very low, is unfavorable for the raising of heat dissipation performance.Latter two method is to improve the common method of metal comprehensive performance, but work
Skill is more complex, and energy consumption is high, and is also possible to phenomena such as generating oxidation or interfacial reaction when high temperature burns and refines and leads to material property
Reduction.
Using in-situ inserted metal to graphene synusia, the heat conducting film being then pressed into has CN102807845A in Z-direction
Higher heat dissipation dynamics, in addition the thermal conductivity that the direction graphene XY is high, so that whole heat dissipation performance is improved, but not to stone
Black alkene this body structure of lamella and aspect of performance have improvement.It is multiple that CN103192072A proposes a kind of thin graphene/metal-powder
Structural material and preparation method are closed, is mixed using transition metal powder with thin graphene, further by CVD in metallic particles
Surface grows coated graphite alkene, and obtains the metal-powder that thin graphene is put up a bridge and coated, but not to graphene itself
Defect is repaired, and in addition the welding between graphene synusia is not also accomplished.CN103021503A proposes the oxidation preparation
Graphene is mixed with various at carbon precursor, and the laminated film for then carrying out thermal reduction preparation has the electric conductivity significantly improved
Can, but the defect without fundamentally repairing graphene and welding graphene sheet layer, because at a lower temperature, decomposing
Carbon can only be that the form of shortrange order or amorphous exists, and does not mention the raising of heating conduction.Patent
CN102385938 develops a kind of technique of Metal Substrate graphene composite material, and using metal as matrix, graphene is as increasing
It is added to by force, so that composited contact material can satisfy the application of electrical contact, does not relate to the reparation to graphene defect
And welding graphene sheet layer.
Although in the above method that graphene and metal material progress is compound, graphene and its derivative are in polymer
Bad dispersibility in matrix, it is easy to reunite, it needs to carry out it functional modification, modified graphene changes original graphene
Structure makes it in thermally conductive aspect declines.Metal material has good thermal conductivity, is remarkably improved with graphene combination poly-
Object thermal conductivity is closed, but metal is poor with polymer compatibility, interface cohesion is difficult and is difficult to be formed effective heat conduction network, can be tight
The propagation for hindering hot-fluid again, to influence the heating conduction of its material.Therefore, urgent need prepare a kind of graphene and metal material compared with
Good is compatible, and the composite material with Thermal conductivity.
