Abstract
A magnet module used for producing a carbon nanotube dispersion liquid, comprising: a pipe portion having a first opening connected to a shearing module, and a second opening at both ends; and a magnet disposed in the pipe portion, wherein a medium liquid containing the carbon nanotube defibrated by the shearing module is supplied through the first opening, and after a ferromagnetic impurity attached to the carbon nanotube is attracted to the magnet and removed, the medium liquid is discharged from the second opening.
Claims15
