Description
Art:
The present invention relates to field of new, a kind of preparation method of carbon nanotube conducting glass.
Background technology:
Carbon nanotube is that graphite flake is curling according to certain helix angle, diameter is nano level tube-like materials.It has very large length-to-diameter ratio, and heat exchange performance is alongst very high, and the heat exchange performance of its relative vertical direction is lower, and by suitable orientation, carbon nanotube can synthesize the heat conducting material of high anisotropy.The Van der Waals force stronger due to carbon nanotube self and very large length-to-diameter ratio, cause it very easily to reunite in process of production.And in use, often the coacervate of carbon nanotube fully will be disperseed just can reach desirable result of use.
ITO conductive glass is on the basis of sodium calcium base or silicon boryl substrate glass, utilizes the multiple methods such as sputtering, evaporation to plate indium oxide layer tin (being commonly called as ITO) film and manufactures.Liquid-crystal display special I TO conductive glass, also before plating ITO layer, can plate layer of silicon dioxide blocking layer, spreads to stop the sodium ion in substrate glass in liquid crystal in box.High-grade liquid-crystal display special I TO glass substrate glass before sputter ITO layer also will carry out polished finish, to obtain evenly display and control.ITO is a kind of indium tin metal oxide compound, and be most popular material in touch-screen instantly, and indium is a kind of rare metal, global storage only surplus 1.6 ten thousand tons, the alternative material therefore finding a kind of performance close is regarded as Breakthrough in Industry mouth by industry.
Within 2002, Jiang Kaili study group of Tsing-Hua University has delivered the work about pulling out continuous long line from carbon nano pipe array first on nature, for dry process carbon nano tube transparent conducting film is afterwards laid a good foundation.Can extract out in carbon nano pipe array on a silicon substrate and reach 30cm, the pure nano-carbon tube line of wide 200 μm.Research finds, the carbon nano pipe array being only called as " super in-line arrangement " just directly can pull out line, and the line pulled out is the film that one deck is very thin after amplifying, and forms by the filament that a lot of hundreds of nanometer is thick is arranged in parallel.On the carbon nanotube of super in-line arrangement, at edge pull-up one head, upright carbon nanotube can be evened up and lie, the nanotube being originally 200 microns high, with regard on one one overlap joint, just as silk cocoon reels off raw silk from cocoons, has been pumped into a line.If the head of pull-up is enough wide, be just pumped into a film.Carbon nano-tube film paving on the glass substrate, the printed electrode on both sides, has just made carbon nanotube conducting glass.The carbon nano tube growth cost of super in-line arrangement is high, and require high to growing environment, therefore the current cost for making conductive glass is higher, and can not prepare large-area film by the restriction of growth apparatus.
Summary of the invention:
For above-mentioned the deficiencies in the prior art, the invention provides a kind of preparation method of carbon nanotube conducting glass, the method not only without the need to growing super in-line arrangement carbon nanotube, and avoids the pollution produced with dispersion agent during wet-layer preparation carbon nanotube conducting glass.
The technical solution adopted in the present invention is: the carbon nanotube of gas phase dispersion runs from top to bottom along running pipeline under air-flow guides, and is running the glass basis of placement surface gluing on pipeline, and carbon nanotube falls and is evenly attached to Jiao Mianshang afterwards, constantly deposits.Carbon nanotube conducting glass is obtained after solidification treatment.
Its preparation technology comprises the following steps:
(1) carbon nanotube of gas phase dispersion runs from top to bottom along running pipeline under air-flow guides;
(2) glass basis of surface coating is positioned over and runs on pipeline, receives the carbon nanotube of gas phase dispersion;
(3) carry out the regular hour, make glass basis adhere to appropriate carbon nanotube;
(4) be cured process, carbon nanotube is firmly attached on glass basis.
The invention has the beneficial effects as follows, provide a kind of method that low cost prepares carbon nanotube conducting glass, the carbon nanotube conducting glass of all size can be prepared in a large number.
