摘要:
Carbon nanotube structures are provided, in which the networks with a desired area and volume, where the carbon nanotubes are electrically or magnetically connected, are formed and the method for easily manufacturing the carbon nanotube structures with less carbon nanotube structures. Carbon nanotube devices are also provided, to which the useful carbon nanotube structures mentioned above are applied. A method for manufacturing carbon nanotube structures includes the steps of applying carbon nanotubes to a low-viscosity dispersion medium to obtain a high-viscosity dispersing liquid which includes carbon nanotubes, and forming a network of the carbon nanotubes having electrical and/or magnetic connections therebetween by removing the low-viscosity dispersion medium from the high-viscosity dispersed liquid.

Carbon nanotube structures which enhances handling of carbon nanotubes, enabling them to be applied in a wide variety fields such as electronic devices, functional materials, and structural materials containing carbon nanotubes, and a method for producing them are provided. A method for manufacturing carbon nanotube structures includes the step of forming liquid bridges of a liquid at gaps among plural objects and/or at plural gaps among portions of an object. The plural carbon nanotubes are dispersed in the liquid and linked together, then arranged structurally to the liquid bridges, and the carbon nanotube structures are manufactured in this way.
