Carbon nanotube dispersion and method for manufacturing dispersion

Abstract

Disclosed is a manufacturing method, which includes: loading a liquid medium into a dispersing container; loading carbon nanotubes into the dispersing container and adjusting the viscosity of the contents of the dispersing container to a prescribed loading target value; and subjecting the contents of the dispersing container to a dispersion treatment using an annular gap-type bead mill and bringing the viscosity of the contents to a prescribed dispersion target value. A characteristic feature of this manufacturing method is that carbon nanotube loading and the dispersion treatment are repeated until the carbon nanotube concentration of the contents of the dispersing container reaches a desired value. This manufacturing method can bring about a homogeneous dispersion even with a high-concentration carbon nanotube dispersion.
