Description
Technical field
The invention belongs to graphene radiating technical field of membrane, more particularly to a kind of moistureproof graphene heat dissipation film.
Background technology
Graphene is a kind of cellular flat film formed by carbon atom with sp2 hybrid forms, is a kind of only one
The quasi- two-dimensional material of atomic layer level thickness, monoatomic layer graphite is done so being called, Univ Manchester UK physicist An De
Lie Gaimu and Constantine's Nuo Woxiao loves, graphene is isolated from graphite with micromechanics stripping method success, therefore altogether
With obtaining Nobel Prize in physics, the method for the common power production of graphene is mechanical stripping method, outside oxidation-reduction method, SiC
Epitaxial growth, film production method are chemical vapour deposition technique（CVD）, due to its very good intensity, it is flexible, conductive, lead
Heat, optical characteristics, significant progress is obtained in fields such as physics, materialogy, electronic information, computer, Aero-Space.
Graphene is a kind of magical nanoscale new material, with translucency is good, thermal conductivity factor is high, resistivity is low, electronics
Mobility is high, high mechanical properties feature, can substitute original efficient performance of materials serve (such as) thus in many application fields
Substitute silicon, turn into " king of 21st century new material ".
By taking field of batteries as an example, compared with conventional electrode materials, graphene has high capacity density, high power density, electricity
Pool structure optimizes the advantage such as more preferable with performance.Graphene is applied in lithium battery, can greatly improve battery capacity, be new energy
Automobile solves the problems, such as continuation of the journey.
Based on the outstanding performance of graphene, each state all is doing one's utmost to promote graphene industrialized development, graphene correlation
Technical research be included in the support project of the state such as the U.S., Britain, Japan and South Korea field of new materials emphasis.But, as new
Emerging industry, graphene industrialization process, which collects still, many weak points.Graphene industrial chain is also extremely weak, is not formed
Completely, ripe industrial chain upstream and downstream, it is main feature that graphene research and development, which prepare enterprise and the disconnection of downstream application enterprise,.
Graphene the kind scale application for not fully achieving graphene, produces still in industrialization initial stage to graphene at present
The maximum market of product is still research institutions and a small amount of production firm.Because downstream demand does not rise, most of graphene enterprise
Industry can not still find stable business model and profit model at present.
The difficult point of graphene large-scale commercial application is hindered to be two aspects：From the point of view of in technique, how mass
Preparing that large area, stability is good, graphene of high quality is one of difficult point, whole industry is still in the research and development of products stage at present,
Only a small number of enterprises can prepare high-quality graphene on a large scale, and the fraction defective of industry aspect have impact on the application in downstream；
Seen in sale aspect, enterprise, which can not still stablize, in the industry obtains profit, how to integrate vertical industry chain, that is, promoting or sell will
As the key of graphene industry development.
China's graphene industry development impetus is swift and violent, but the strong downstream in upstream is weak, scientific research is gently applied again, amusement is done solid work less more
It is the bottleneck that industry development need break through Deng reality.Although the cost of production graphene is constantly reducing now, can be real
Border is limited using the downstream volume production product of graphene, and the application market of graphene does not discharge also on a large scale, therefore causes production capacity
It is superfluous.
As electronic device product gradually doubles therewith to high integration, the development in high computing field, dissipated power, radiating
Have become a problem urgently to be resolved hurrily.All the time, the radiating effect of the traditional heat sinks such as copper, aluminum is widely connect
By, however metal material exist be difficult to process, consuming energy, excessive, the difficult recovery of conductive, yielding and waste material of density etc. it is many
Problem.
The graphite radiating film with high thermal conductivity coefficient gradually occupies the market of dissipation from electronic devices in recent years.
At present graphite radiating film be widely used in telecommunications industry, Medical Devices, SONY/DELL/Samsung notebooks,
In emerging mobile phone, Samsung PDP, PC memory bars, LED substrates etc. radiating etc..
With the discovery of graphene, it has been found that with graphite-phase ratio, graphene has more superior heat dispersion, with graphite
Heat dissipation film heat dispersion can be significantly better than graphite made of alkene.
Existing graphene heat dissipation film function is relatively simple, without moisture-proof function, while can not carry out sun-proof and wear-resisting.
