Title:
METHOD FOR REMOVING METAL ION FROM FLUID DISPERSION CONTAINING CARBON NANOTUBE, CARBON NANOTUBE DISPERSION, AND CARBON NANOTUBE-INCLUDING FILM
Document Type and Number:
Japanese Patent JP2018008838
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a high purity CNT dispersion with no metal impurities, which is excellent in film making property and moldability, and can manufacture a CNT dispersion containing CNT uniformly dispersed in a dispersant at high concentration and can be coated on a substrate with a simple method, and provide a high purity CNT-including film containing no metal impurity formed from the CNT dispersion.SOLUTION: The method for manufacturing a purified CNT dispersion can remove a metal ion from a CNT dispersion, which is a raw material obtained by mixing an OHtype anion exchanger and a Htype cation exchanger, with 10% to 90% of OHtype anion exchanger equivalent ratio, filling the same into a column for purification, and passing the CNT dispersion which is the raw material through the column.SELECTED DRAWING: Figure 1
