Embodiment Construction

[0040] figure 1 A container 1 is shown in which contains a liquid with a surfactant and a homogeneous dispersion 2 of a plurality of carbon nanotubes 3 . In further embodiments, only a single carbon nanotube with predetermined electrical properties may also be used as a starting material for the method. The liquid in the embodiment shown is distilled water, however, deionized water can also typically be used. In the embodiment shown, the surfactant (sodium dodecyl sulfate (SDS)) was present in the dispersion at a concentration of 0.1 wt.%. Furthermore, isopropanol is already mixed in the dispersion, but isopropanol can also be omitted in other embodiments. As an example, one of the carbon nanotubes 3 is shown enlarged. At least 90% of the carbon nanotubes 3 contained in the dispersion 2 have the same electrical properties and are therefore semiconducting in the embodiment shown, and preferably have the same size diameter and the same chirality. In addition, all the carbon...

Abstract

The invention relates to a method for regenerating at least one single-walled carbon nanotube (3) with predetermined electrical properties or a plurality of single-walled carbon nanotubes (3) with the same electrical properties. For this purpose, a dispersion (2) is prepared and the carbon nanotubes (3) contained in said dispersion (2) are processed into fragments (6) by inputting energy. The segments ( 6 ) are applied to a carrier ( 7 ) and oriented on the carrier ( 7 ). Subsequently, the segments ( 6 ) are extended by chemical vapor deposition, and thus the initially present carbon nanotubes ( 3 ) are regenerated.

Description

technical field [0001] The present invention relates to a method for growing vertically oriented single-walled carbon nanotubes with identical electrical properties and for regenerating single-walled carbon nanotubes with identical electrical properties. Background technique [0002] Carbon nanotubes are promising candidates for future technological applications due to their exceptional properties. Carbon nanotubes can, for example, be metallic or semiconducting, depending on their diameter and their helicity and / or their chirality. However, the production methods from the prior art result in a mixture of different types of carbon nanotubes (ie multi-walled, single-walled metallic carbon nanotubes and semiconducting carbon nanotubes), which then have to be separated from one another with great difficulty. Therefore, it is still not possible to directly fix the diameter and chirality of the fabricated carbon nanotubes during fabrication. [0003] Single-walled carbon nanotu...
