Problems solved by technology

[0006] However, in the construction and production method of the above-mentioned antistatic layer, the dispersant hinders the mutual contact of the carbon nanotubes, making it difficult to utilize the inherently excellent electrical conductivity of the carbon nanotubes.
Therefore, in order to obtain the desired conductivity, it will be required to add a large amount of carbon nanotubes, which will cause a decrease in transparency
In addition, it is difficult to uniformly disperse carbon nanotubes in thermoplastic resin, so that uniform conductivity cannot be obtained in the antistatic layer

Abstract

Disclosed herein is a light-transmitting electric conductor including, on a surface of a light-transmitting support, a conductive material in which a multiplicity of carbon nanolinear structures are accumulated in two dimensions while making partial contact with each other, wherein the conductive material is a light-transmitting conductive material composed only of the carbon nanolinear structures, and direct bonds are formed between the surface of the light-transmitting support and the carbon nanolinear structures making contact with the surface, and between the carbon nanolinear structures making contact with each other.

Description

technical field [0001] The present invention relates to a light-transmitting conductor having excellent light-transmitting and electric-conducting properties, a manufacturing method thereof, a static elimination sheet and an electronic device. In particular, the present invention relates to light-transmitting conductors employing carbon nanolinear (nanofilament) structures such as carbon nanotubes and methods of manufacturing the same. Background technique [0002] Transparent conductive films have been used as transparent electrodes for electronic devices involving light in / out, such as liquid crystal displays and touch panels, and static eliminator films for light-transmitting members where dust deposition is undesirable, such as clean rooms in the divider. As a material of such a transparent conductive film, for example, inorganic oxides such as indium tin oxide (ITO) and inorganic fluorides such as fluorine-doped tin oxide (FTO) have been used. However, these oxides an...
