Glutinous agent technical field.
Background technology
With the fast development of electronic product, people are particularly ultra-thin to the requirement also more and more higher of portable degree, functionality
The design of panelized, now from mobile phone to computer, volume is less and less, and function is stronger and stronger, is got over which results in integrated level
Come higher, so it is more and more stricter to the cooling requirements of the electronic component on electronic circuit board.Traditional electronic product is used
Fan radiating system, but this system bulk is big, noise is big, be no longer desirable for present electronic product demand and gradually
It is eliminated.Also, simple heat sink material can not effectively play radiating effect to electronic component, and heat conduction pressure sensitive adhesive is pasted
Between electronic component and heat sink material, play a part of connection, barrier between the two can be reduced, effectively improve radiating
Effect.Therefore it is widely used in LCD, semiconductor, in the electronic component such as integrated circuit.With continuing to increase for human demand,
And then other heat sink materials, such as copper foil, aluminium foil are generated, but be due to that this kind of heat sink material is expensive, radiating effect
Production requirement can not be reached, slowly, the new efficient heat sink material of a class occurs in that this kind of material includes carbon fiber, receives
Rice carbon pipe, graphene, diamond film etc..The thermal conductivity of this kind of material is very high, and especially highly-conductive hot carbon fiber axially has
Highest 1200W/mk thermal conductivity, the highest thermal conductivity factor of diamond film is 2200W/mk, and high heat conduction graphene is along flat

And, different types of graphene all has respective advantage and disadvantage, and wherein graphene oxide contains substantial amounts of functional group, therefore can be with
Stable dispersion in organic solvent and can also carry out large-scale production, but substantial amounts of oxygen-containing functional group can cause structure to lack
Fall into, decline its heat conductivility.Modified graphene has good dispersiveness, but its complex manufacturing, and efficiency is low.Reduction-oxidation
Graphene, which equally exists substantial amounts of fault of construction, reduces its heat conductivility., can be big but physics stripping graphene-structured defect is small
Large-scale production, simple production process can effectively improve electrical and thermal conductivity performance.
