The invention also relates to the manufacturing method forthe carbon nano tube device.

Description

technical field [0001] The present invention relates to a carbon nanotube device and a manufacturing method thereof. Background technique [0002] Carbon nanotube is a kind of one-dimensional nanomaterial with hollow structure of carbon fiber discovered by Japanese scientists in 1991. Theoretical and experimental studies have confirmed that carbon nanotube-like structural materials have many excellent and peculiar properties. For example, the mechanical properties of carbon nanotubes are the highest among the materials found in nature. Its density is 1 / 6 times that of steel, and its strength is 1 / 6. It is 100 times that of steel, and carbon nanotubes not only have high tensile strength, but also high impact toughness, which is unmatched by general materials. Many excellent properties of carbon nanotubes are manifested in the axial direction. How to orientate carbon nanotubes and make full use of the excellent one-dimensional properties of carbon nanotubes has always been on...

Problems solved by technology

[0003] At present, there are two main methods for manufacturing aligned carbon nanotube films: one is to directly deposit aligned carbon nanotube arrays on rigid substrates such as quartz substrates, silicon substrates, and high-temperature-resistant metal materials. Although the film has rigidity and high temperature resistant substrate, it is precisely this that severely limits the application range of arrayed carbon nanotubes; the other is to compound carbon nanotubes and polymers into a composite film, and the carbon in this composite film The orientation of the nanotubes is randomly distributed. By slicing, a part of the carbon nanotubes can be exposed from the film, and a part of the carbon nanotubes can be distributed in the same orientation in the film. However, in this composite film, since the orientation of the carbon nanotubes is At the same time, in the process of composite material mixing, carbon nanotubes are not uniformly dispersed, which will reduce the density of carbon nanotubes distributed in the same phase, which will greatly affect the performance of carbon nanotube films.
