Description
Technical field
The invention belongs to thermally conductive and technical field of heat dissipation, be related to nanometer carbon pipe array/graphite composite heat-conducting membrane material and its
Preparation method.
Background technique
In recent years, graphite film material was answered extensively because of its excellent high thermal conductivity, heat-resisting, the corrosion-resistant and characteristics such as highly conductive
For technical fields such as electronic product heat dissipation, heat-resistant seal material, heaters.And the graphite film with high thermal conductivity is even more
It is widely used under smart phone and tablet computer equidimension, in the handheld terminals such as electronic component is intensive, calorific value is big, passes through height
Thermal conductivity realizes heat sinking function.
Currently, can be had by selecting organic polymer thin-film material directly to carry out carbonization and graphitization processing
High-termal conductivity, high conductivity, the graphite film material of resistance to bend(ing) (104445174 A of CN 102838107 B, CN etc.), and
It is widely used in handheld terminal.Although the type conduction graphite film can be by heating device easy in handheld terminal
Heat conduct rapidly in entire graphite film, but being limited swept area causes it heat promptly cannot be radiated week
In collarette border, as a result, the cruising ability of heat dissipation is insufficient.Cause heat dissipation cruising ability insufficient main reason is that thermally conductive
The lesser swept area of film, and thereby result between heat conducting film and air that there are biggish interface resistances.
Carbon nanotubes has the excellent characteristics such as high heat conductance, high conductivity, high-specific surface area and high intensity, in macromolecule
The fields such as material, metal material, ceramic material play significant reinforcing effect.By the way that carbon nanotubes is mutually tied with graphite film
It closes, can effectively enhance the thermal conductive contact between substrate, and the adhesive force and splitting resistance of Heat Conduction Material can be improved
Can, so as to improve the overall performance of thin-film material.
In this regard, 104810336 A of Chinese patent CN discloses a kind of heat transmission carbon nanotube composite stone ink film, in graphite
The direct carbon nano-tube coating layer of film surface (carbon nanotube heat dissipating layer includes carbon nano-tube material, auxiliary agent and binding resin) increases
The capacity of heat transmission of vertical direction, while improving the mechanical property and flexility of heat conducting film.But due to carbon nanotubes and stone
The active force on ink film surface is poor, carbon nanotubes random distribution and cause to orient it is poor, and coating carbon nanotubes it is easy to reunite
And effective swept area cannot be increased by causing specific surface area reasons, the gained composite stone ink film such as substantially to decline.Chinese patent CN
105110312 A disclose carbon nanotube graphite composite material and preparation method thereof and device, pass through carbon using complete wet filtration method
Composite membrane is made in nanotube dispersion liquid and graphite dispersing solution, and it is thin to solve the problems, such as that natural graphite is difficult to, increases simultaneously
The capacity of heat transmission of vertical direction.However, the material has the following deficiencies: that only abutment surface adhesive force connects carbon nanotubes with graphite flake
Even, final products globality and continuity are poor；The graphite flake of carbon nanotubes and low specific surface area mutually coats and easy to reunite, leads
It causes whole specific surface area to reduce, not can increase effective swept area；Carbon nanotubes random distribution, directionality is poor, heat without
Method is conducted towards preset direction and is spread.104029461 A of Chinese patent CN discloses a kind of graphene/carbon nano-tube/graphite film
Composite material and preparation method prepares nickel Catalytic Layer in graphite film surface using magnetic control sputtering system, and be vapor-deposited graphene
With carbon nanotubes particle, the three-dimensional net structure of graphene and carbon nanotubes preferably promotes the heating conduction of material.But
Granular graphene and carbon nanotubes causes specific surface area to reduce significantly because it reunites the shortcomings that, and effective radiating area cannot get
It is obviously improved；In addition, the random distribution of graphene and carbon nanotubes causes poor directionality to cause in three-dimensional net structure
Heat radiation is difficult to carry out towards preset direction.
It can be seen that existing graphite and the composite film material of carbon nanotubes are focused on how to promote material plane direction
Or the thermal coefficient of vertical direction, and for how heat to be quickly directionally diffused into this technology in the surrounding enviroment such as air
Problem, which then rarely has, to be related to.In the preparation method of existing graphite and carbon nanotubes composite film material, cladding process and complete wet filtration method
Since carbon nanotubes passes through the randomness that dispersion causes distribution, the nanometer carbon pipe array and graphite of high orientation cannot be formed
The composite film material of film；And the random distribution for the carbon nanotubes particle that is vapor-deposited, the astaticism of carbon nanotubes is caused, together
Sample cannot form the nanometer carbon pipe array of high orientation and the composite film material of graphite film.This has just been doomed the above material not
Effective swept area can be significantly increased, so quickly heat directionally cannot be diffused into the surrounding enviroment such as air.In addition,
The composite film material of existing graphite and carbon nanotubes introduces carbon nanotubes on the basis of molding graphite film,
Its process is complex, larger for the change of original process units, is unfavorable for continuous production.
