Description
Technical field
The present invention relates to a kind of carbon nano tube dispersion method, carbon nanotube dispersed effectively can be made also can to obtain the method for a large amount of single-root carbon nano-tube, belong to the field of dispersions of nano material.
Background technology
CNT is that graphite flake is curling according to certain helical angle, diameter is nano level tube-like materials.It has very large draw ratio, and heat exchange performance is alongst better, and the heat exchange performance of its vertical direction is lower, utilizes its anisotropy by suitable orientation, can obtain the composite with superior heat conductivility.But owing to having stronger Van der Waals force between CNT, add its very large draw ratio, cause it very easily to occur reunite thus reduce its performance in production and application process.And in use, often the aggregate of CNT fully will be disperseed just can reach desirable result of use.The dispersing apparatus of current CNT mainly uses sonic oscillation, ball mill etc. to realize the dispersion of CNT.By use the said equipment dispersing Nano carbon tubes have dispersion not thoroughly, longevity of service, have the shortcomings such as certain destructive and dispersion efficiency is low to CNT.
Summary of the invention
Dispersion for prior art appearance when carrying out carbon nanotube dispersed deficiency that is uneven, that easily mix with medium, the invention provides a kind of method of efficient, free of contamination dispersing Nano carbon tubes, even carbon nanotube dispersion can be realized, its preparation facilities is simple and control is convenient, and use and maintenance cost is low.
For solving the problem, the present invention solves its technical problem and adopts technical scheme is:
The carbon nanotube dispersed device that the method adopts mainly contains upper and lower two battery lead plates, extra-high-tension pulse generator, anion generator, poly (methyl methacrylate) plate, sealing ring, mould loft floor, sampling bench, and support forms.After mould loft floor put into by sample, by opening of device, closing device after a period of time, takes out sample from sampling bench.
The invention has the beneficial effects as follows, provide a kind of method of effective dispersing Nano carbon tubes.The present invention is effective and efficiency is high to carbon nanotube dispersed, and preparation facilities is simple and control convenient, and use and maintenance cost is low.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this equipment, and in figure, 1,2 is metal electrode boards, and 3 is anion generator or extra-high-tension pulse generator, and 4 is plexiglass tents, and 5 is mould loft floors, and 6 is sampling bench, and 7 is supports, and 8 is sealing rings, and 9 is power supplys.
Detailed description of the invention
CNT is put into mould loft floor 5, and by pole plate 1 earth connection, pole plate 2 is connected with extra-high-tension pulse generator or anion generator 3.
Scheme one: when pole plate 2 is connected with extra-high-tension pulse generator 3, need be connected with the power supply 9 of 6V, and the input voltage of extra-high-tension pulse generator 3 is 3.6-6V, and output voltage is 30-60 ten thousand V,
Scheme two: need be connected with 220V power supply when pole plate 2 is connected with anion generator 3, anion generator 3 input voltage 220V output voltage 18KV.
Cover equipment with 4 plexiglass tents after aforesaid operations and seal with 8 bands, switch on power and carry out a period of time, make homogeneous spark electric discharge between battery lead plate, pull out power supply after a period of time and turn off equipment, CNT is taken out, the degree of scatter of electron microscopic observation CNT from sampling bench 6.
Operation principle of the present invention
By the electrical potential difference existed between two battery lead plates, carry out spark discharge, sample can be broken up by electric spark in a device uniformly, reaches the effect of dispersion.
