Description
Technical field
The invention belongs to heat conduction and technical field of heat dissipation, relate to the system of a kind of graphite/nanometer carbon pipe array composite heat conduction film
Preparation Method.
Background technology
In recent years, graphite film material, because of characteristics such as the high heat conduction of its excellence, heat-resisting, corrosion-resistant and high connductivity, extensively should
For technical fields such as electronic product heat radiation, heat-resistant seal material, heaters.And there is the graphite film of high thermal conductivity especially
It is widely used under smart mobile phone and panel computer equidimension, electronic component is intensive, caloric value is big etc. in handheld terminal, by height
Thermal conductivity realizes heat sinking function.
At present, by selecting organic polymer thin-film material directly to carry out carbonization and graphitization processing, it is possible to had
High-termal conductivity, high conductivity, the graphite film material (CN 102838107 B, CN 104445174 A etc.) of resistance to bend(ing), and
It is widely used in handheld terminal.Although this type conduction graphite film can be by heater members easy in handheld terminal
Heat conduct rapidly in whole graphite film, but limited swept area causes it that heat can not promptly be radiated week
In collarette border, its result is that the flying power of heat radiation is not enough.That causes heat radiation flying power deficiency main reason is that heat conduction
The swept area that film is less, and thereby result in and between heat conducting film and air, there is bigger interface resistance.
CNT has the characteristic that high heat conductance, high conductivity, high-specific surface area and high intensity etc. are excellent, at macromolecule
The fields such as material, metal material, ceramic material serve significant reinforced effects.By CNT is tied mutually with graphite film
Close, can effectively strengthen and thermal conductive contact between substrate, and adhesive force and the splitting resistance of Heat Conduction Material can be improved
Can such that it is able to improve the overall performance of thin-film material.
To this, Chinese patent CN 104810336 A discloses a kind of heat transmission CNT composite stone ink film, at graphite
Film surface direct carbon nano-tube coating layer (CNT heat dissipating layer includes carbon nano-tube material, auxiliary agent and binding resin), increases
The capacity of heat transmission of vertical direction, improves mechanical property and the flexility of heat conducting film simultaneously.But due to CNT and stone
The active force on ink film surface is poor, and CNT random distribution and causing orients poor, and the CNT of coating is easily reunited
And the reason such as cause that specific surface area declines to a great extent, gained composite stone ink film can not increase effective swept area.Chinese patent CN
105110312 A disclose CNT graphite composite material and preparation method thereof and device, use complete wet Filtration to pass through carbon
Nanotube dispersion liquid and graphite dispersing solution make composite membrane, solve native graphite and are difficult to thin problem, add simultaneously
The capacity of heat transmission of vertical direction.But, there is following defect in this material: CNT and graphite flake only abutment surface adhesive force connects
Even, final products globality and seriality are poor；CNT is mutually coated with the graphite flake of low specific surface area and easily reunites, and leads
Cause overall specific surface area to reduce, it is impossible to increase effective swept area；CNT random distribution, directivity is poor, heat without
Method is towards preset direction conduction diffusion.Chinese patent CN 104029461 A discloses a kind of graphene/carbon nano-tube/graphite film
Composite and preparation method thereof, uses magnetic control sputtering system to prepare nickel Catalytic Layer, vapour deposition Graphene in graphite film surface
With the heat conductivility that the three-dimensional net structure of CNT granule, Graphene and CNT preferably promotes material.But,
Shortcoming that granular Graphene and CNT are reunited because of it and cause specific surface area to be greatly reduced, effective radiating area can not get
It is obviously improved；Additionally, Graphene and the random distribution of CNT cause poor directionality to cause in three-dimensional net structure
Heat radiation is difficult to carry out towards preset direction.
As can be seen here, existing graphite is focused on how promoting material plane direction with the composite film material of CNT
Or the heat conductivity of vertical direction, and for the most quickly heat being directionally diffused into this technology in the surrounding enviroment such as air
A difficult problem then rarely has and relates to.In the preparation method of existing graphite and CNT composite film material, cladding process and complete wet Filtration
Owing to CNT is through disperseing the randomness causing distribution, nanometer carbon pipe array and the graphite of high orientation therefore can not be formed
The composite film material of film；And the random distribution of vapour deposition CNT granule, cause the astaticism of CNT, with
Sample can not form the nanometer carbon pipe array of high orientation and the composite film material of graphite film.This has just been doomed above material the most not
Effective swept area can be significantly increased, so can not be quickly directionally diffused in the surrounding enviroment such as air by heat.Additionally,
Existing graphite and the composite film material of CNT, all introduce CNT on the basis of the graphite film of molding,
Its process is complex, and the change for original process units is relatively big, is unfavorable for continuous prodution.
Summary of the invention
It is an object of the invention to provide the preparation method of a kind of graphite/nanometer carbon pipe array composite heat conduction film, at graphite film
Surface deposition has the nanometer carbon pipe array of high directivity, and the effective radiating area of conduction graphite film is significantly increased, and reduction is led
Interface resistance between hotting mask and air, significantly improves the heat exchange amount of the surrounding enviroment such as unit are heat conducting film and air, reach by
Heat is quickly diffused into the effect the surrounding enviroment such as air from heat conducting film.
