It can be understood that since the super-sequential carbon nanotube array of the present embodiment is very pure ' ^ because the specific surface area of the carbon nanotube itself is very large: household: to: the second carbon nanotube structure 32 itself has a relatively Strong sticky. Because the field tool 'such as - the recording of the second carbon nanotube structure % _ ^ extension direction makes the second carbon nanotube structure 3 2 end and the third structure close to the carbon nanotube array 1G The end-to-end contact, the j-n-carbon tube structure 32 partially overlaps with the first-nine carbon tube structure 30, and the van der Waals force is attached.

In the present embodiment, a drop bottle 42 is placed in the third carbon nanotube structure 34, and a drop 45 is placed at the bottom of the drop bottle 42 with the organic solvent from the drip opening = on the surface of the third carbon nanotube structure 34. The organic solvent 44 is a volatile organic solvent 44 such as ethanol, methanol, propylamine, dichloroethane or chloroform. In the present embodiment, ethanol is preferably employed. After the third carbon nanotubes 34 are infiltrated by the organic solvent 44, 'the parallel carbon nanotube fragments will partially aggregate into the nano carbon & bundle' under the action of the volatile organic solvent 44. The third carbon nanotube structure 34 is contracted into a carbon nanotube gauze treated with an organic solvent 44, and the surface area of the carbon nanotube yarn is smaller than that of the field, and has no mechanical strength and good character. In the macro field. Further, the carbon nanotube yarn treated with the organic solvent 44 may be dried by a drying step. Specifically, the above-mentioned treatment with the organic solvent 44 can be passed through: the drying box 48'. The temperature of the drying box 48 is 8 〇 γ Γ 1 〇〇 = the organic solvent in the carbon nanotube yarn is volatilized . #, It is also possible to dry the organic solvent 13 201014789 44 of the carbon nanotube yarn treated by the organic solvent Lu #人风(四) agent.

The drop bottle 42 containing the organic t correct 44 is placed first Above the carbon nanotube structure 30, the organic drip 46 is continuously dripped on the surface of the first carbon nanotube structure, so that the first carbon nanotube structure 3 which is continuously pulled out is continuously shrunk into a nano carbon tube yarn _ W 4 〇 (4) (4) _ 48 (4) 'The most (four) around the tube array 'When the first-nano carbon nanotube structure 30 is going to be pulled out from the nano-carbon barrier Μ 4, using a stretching tool, the second 奈The rice is out === the middle portion is pulled out, and the solvent-treated portions are overlapped to connect the organic rice carbon nanotube structure 32. Li After the ring is rotated by the reel 50, the second 201014789 carbon nanotube structure 32 is also continuously pulled out from the other carbon nanotube (four) ι, along with the first carbon nanotube structure 3〇, through the money solvent After the material processing and the dry box 48 are pure, the carbon nanotube yarn 40 is formed and wound on the coil 50, thereby lengthening the length of the carbon nanotube yarn 40. The carbon nanotube yarn obtained through the above steps The diameter is 〇·5奈来~i mm. It can be understood that, in order to meet the needs of practical applications, the conventional carbon fiber yarn can be further twisted, plied and woven by the conventional yarn method in the prior spinning process. The processing method can obtain different thick and thin tube yarns. The preparation method of the nano carbon tube yarn provided by the technical solution has the following advantages: First, the connection of a plurality of carbon nanotube structures by end-to-end connection is used to make the original Some nano carbon tube structures are extended in length, and after being treated with an organic solvent, nano carbon tube yarns are obtained, so that the length of the nano carbon tube yarn is not limited by the size of the substrate, so that the required length of nano carbon can be conveniently obtained. Banknotes. Its - The carbon nanotube yarn obtained by the above method has good electrical conductivity, thermal conductivity and mechanical properties' and has sufficient length, and can be widely applied to macroscopic fields such as electromagnetic shielding (4), printed circuit boards and various protective clothing textiles. The invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above description is only the preferred embodiment of the invention, and the scope of the patent application of the present invention cannot be limited thereto. Equivalent modifications or variations made by persons in accordance with the spirit of the present invention are intended to be included in the scope of the following claims.
