Description
Technical field:
The invention belongs to field of new, relate to the process for dispersing of a kind of CNT.
Background technology:
Nano level tube-like materials that CNT is crimped according to certain helical angle by graphite flake, a diameter of.It has
The biggest draw ratio, heat exchange performance alongst is preferable, and the heat exchange performance of its vertical direction is relatively low, utilizes
Its anisotropy is by suitably orientation, it is possible to obtain have the composite of superior heat conductivility.But due between CNT
There is stronger Van der Waals force, add its biggest draw ratio, cause it easily to reunite during production and application
Thus reduce its performance.And in use, often can be only achieved preferably use by fully dispersed for the aggregate of CNT
Effect.
The excellent properties of CNT makes it have a wide range of applications in military project, space flight and civilian production enterprise, than
Such as the coating of aircraft stealth material, in space material, interpolation CNT is to strengthen its mechanical performance and lighter weight, and
Some civilian High-molecular rubber material, the application of the materials such as Mobile phone screen.But it is excellent that the reuniting effect of CNT have impact on it
The performance of performance, the main dispersion means of present stage China's CNT research field include grinding, ultrasound wave dispersion, strong acid-base
Processing, but these methods are only limitted to the laboratory research stage, the scattered CNT of large-scale production does not the most also have
The solution of effect.The state such as American-European to the research main points of CNT prior to us, but they make our nothing for the block of technology
Method obtains effective scattered method, and the process for dispersing of a kind of CNT that the application is proposed seeks to one can be extensive
The method producing dispersing Nano carbon tubes, breaks developed country's barrier for dispersing Nano carbon tubes method, for China's CNT
Research give a favor, enable CNT to be widely applied in the field such as military project, space flight.
Summary of the invention:
For the deficiency of above-mentioned existing dispersion technology, the invention provides one and disperse the most thorough and quick and can meet
The carbon nano tube dispersion method of industrialization.
Dispersion technology scheme of the present invention is: be first to prepare the CNT with certain proportion mixing and bonding
The carbon nanotube mixture of agent.Then carbon nanotube mixture is added and be pressed into strip shaped electric poles, obtained CNT is mixed
Compound electrode is connected with power supply.Switch on power, make carbon nanotube mixture electrode produces the electric current of sufficient intensity, utilize electrode
The heat effect of middle electric current makes the binding agent rapid vaporization in carbon nanotube mixture, and CNT is produced peptizaiton.
Its preparation technology comprises the following steps:
(1) CNT with certain proportion mixing and the carbon nanotube mixture of binding agent are prepared；
(2) carbon nanotube mixture is added it is pressed into strip shaped electric poles；
(3) obtained carbon nanotube mixture electrode is connected with power supply；
(4) switch on power；
(5) CNT i.e. dispersibles.
The invention has the beneficial effects as follows, it is provided that a kind of dispersion effect substantially and can realize CNT prepared by scale
Process for dispersing.
Accompanying drawing explanation
Fig. 1 is the flow chart of the present invention.
Detailed description of the invention
Concrete implementation that the present invention is further described below in conjunction with the accompanying drawings:
As shown in drawings, the invention provides a kind of carbon nano tube dispersion method.The process for dispersing bag of described CNT
Include step:
(1) CNT with certain proportion mixing and the carbon nanotube mixture of binding agent are prepared；
(2) carbon nanotube mixture is added it is pressed into strip shaped electric poles；
(3) obtained carbon nanotube mixture electrode is connected with power supply；
(4) switch on power；
(5) CNT i.e. dispersibles.
