Benefits of technology

[0061] According to the present invention, a carbon nanotube structure having homogeneous characteristics is obtained making it possible to stably manufacture a device or the like that uses carbon nanotubes. When the obtain

Problems solved by technology

It is very difficult in practice to position carbon nanotubes.
This technique is fine for basic research but takes too much time and labor to provide a practical solution.
The method is capable of aligning carbon nanotubes in one direction, but aligning carbon nanotubes in more than one direction by this technique is difficult and is not realistic.
However, the success rate of cross-linking with the method is very low and it is still difficult with this method to position carbon nanotubes as desired.
However, carbon nanotubes obtained by those methods have been found lacki

Multi-Wall Carbon Nanotube Carboxylic Acid Anhydride Coating Material, Synthesis of a Coat

(Addition Step)

Addition of Carboxyl Group . . . Synthesis of Carbon Nanotube Carboxylic Acid

[0195] 30 mg of multi-layer carbon nanotube powder (purity: 90%, average diameter: 30 nm, average length: 3 μm, a product of Science Laboratory Inc.) was added to 20 ml of concentrated nitric acid (a 60% by mass aqueous solution, a product of KANTO KAGAKU) for reflux at 120° C. for 20 hours to synthesize carbon nanotube carboxylic acid. A reaction scheme of the above is shown in FIG. 2. In FIG. 2, a carbon nanotube (CNT) is represented by two parallel lines.

[0196] The temperature of the liquid solution was returned to room temperature and centrifuged at 5, 000 rpm for 15 minutes to separate supernatant liquid from precipitate. The recovered precipitate was dispersed in 10 ml of pure water, and the dispersion liquid was subjected to centrifugal separation at 5,000 rpm for 15 minutes to separate supe...

Abstract

Provided is a carbon nanotube structure of homogeneous characteristics which is composed of at least a carbon nanotube structure layer where plural carbon nanotubes are cross-linked to one another to form a mesh structure on a surface of a base body. Also provided is a method of manufacturing the carbon nanotube structure which includes: an application step of applying a liquid solution that contains carbon nanotubes having functional groups and an additive for forming chemical bonds between the functional groups to a surface of a base body; and a cross-linking step for forming a carbon nanotube structure layer that has a mesh structure composed of the plural carbon nanotubes that are cross-linked to one another by chemical bonds formed among the functional groups.

Description

FIELD OF THE INVENTION AND RELATED ART STATEMENT [0001] The present invention relates to a carbon nanotube structure with homogeneous characteristics, a method of manufacturing the carbon nanotube structure, a liquid solution for manufacturing the carbon nanotube structure, and a carbon nanotube transfer body which facilitates utilization of the obtained carbon nanotube structure. [0002] Carbon nanotubes (CNTs), with their unique shape and characteristics, are being considered for various applications. Carbon nanotubes have a tubular shape of one-dimensional nature which is obtained by rolling one or more graphene sheets composed of six-membered rings of carbon atoms into a tube. Those that are formed from one graphene sheet are called single-wall nanotubes (SWNTs) while those that are formed from graphene sheet layers are called multi-wall nanotubes (MWNTs). SWNTs are about 1 nm in diameter whereas multi-wall carbon nanotubes measure several tens nm in diameter, and both are far th...
