Abstract
Disclosed herein are a dispersed solution of carbon nanotubes including carbon nanotubes, an organic solvent, a spacer, and a dispersant, and a method of preparing the same. The dispersed solution of the carbon nanotubes includes both the spacer, which reduces the van der Waals force of the carbon nanotubes and prevents bundling of the carbon nanotubes, and the dispersant, which maintains the debundling and stability of the carbon nanotubes, thereby improving the dispersibility of the carbon nanotubes. The method of preparing the dispersed solution of the carbon nanotubes can easily produce a dispersed solution of carbon nanotubes without performing a separate chemical treatment.
