CARBON NANOTUBE AQUEOUS DISPERSION AND COMPOSITE SHEET OBTAINED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain an aqueous dispersion with high concentration and viscosity suitable for coating even when a CNT (carbon nanotube) with a small average fiber diameter (20 nm or less) is to be dispersed, and further to develop application utilizing the dispersion.

SOLUTION: The aqueous dispersion is accomplished by adding the CNT to an aqueous solution including a dispersant composed of a predetermined anionic surfactant and a predetermined polysaccharide and dispersing the CNT therein. In addition, a sheet with excellent electromagnetic radiation controllability and heat-generating property is obtained by applying a coating solution using the dispersion to the sheet substrate.
