Stranded wire

Abstract

The invention relates to a twisted line which comprises a plurality of carbon nano tubes that are connected with each other end to end by van der waals force, wherein the twisted line further comprises conducting materials covering on the surfaces of the carbon nano tubes.

Description

Technical field [0001] The invention relates to a stranded wire, in particular to a stranded wire based on carbon nanotubes. Background technique [0002] Carbon nanotube is a hollow tube rolled from graphene sheets, which has excellent mechanical, thermal and electrical properties. The application field of carbon nanotubes is very broad. For example, it can be used to make field effect transistors, atomic force microscope tips, field emission electron guns, nano templates, and so on. However, at present, carbon nanotubes are basically applied on a microscopic scale, which is difficult to operate. Therefore, assembling carbon nanotubes into a macro-scale structure is of great significance for the macro-application of carbon nanotubes. [0003] Fan Shoushan et al. in Nature, 2002, 419:801, Spinning Continuous CNT Yarns, disclosed that a continuous pure carbon nanotube can be drawn from a super-aligned carbon nanotube array. This carbon nanotube includes multiple The carbon nanotub...

Problems solved by technology

However, since the above-mentioned carbon nanotube segments overlap each other to form a continuous carbon nanotube line, the resistance at the contact point is high, which in turn leads to the low electrical conductivity of the above-mentioned carbon nanotube line, which cannot replace metal wires for signal Transmission and electrical transmission field
