A multi-walled carbon nanotube-containing composition and a method for producing the same, and a method for producing a single-walled and / or two-walled carbon nanotube-containing composition.

摘要

Provided are a multilayer CNT-containing composition excellent in electrical conductivity and stability over time of conductive properties, a method for producing the same, and the like. Moreover, the manufacturing method of the doped single layer and / or 2 layer CNT containing composition which can manufacture the CNT containing composition excellent in the electroconductivity and resistance value stability in a high temperature environment is provided. In the method for producing a multilayer CNT-containing composition of the present invention, when the total number of carbon nanotubes is 100%, a multilayer carbon nanotube containing 35% or more of three or more layers of carbon nanotubes is brought into contact with a bicoordinate boron cation salt. Including a contacting step.
