Abstract

Provided are a system for manufacturing dispersion liquid of carbon nanotubes and a method of manufacturing a dispersion liquid of carbon nanotubes using the same. The system includes; a mixing device supplied with solvent and carbon nanotubes, and storing a admixture of the solvent and the carbon nanotubes; a first dispersion device connected to the mixing device, performing a primary dispersion of the carbon nanotubes by an operation of a rotor and a stator, and then performing a secondary dispersion to form bent portions in the carbon nanotubes while discharging the carbon nanotubes through penetration holes of the stator; and a second dispersion device performing a tertiary dispersion of the carbon nanotubes to selectively cut the bent portions of the carbon nanotubes by irradiating a laser when the secondarily dispersed admixture recirculates to the mixing device.
