Title:
CARBON NANOTUBE LIQUID DISPERSION, PRODUCTION METHOD FOR SEMICONDUCTOR ELEMENT USING SAME, AND PRODUCTION METHOD FOR WIRELESS COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/261891
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a carbon nanotube liquid dispersion that can be applied, by inkjet, at a desired position with higher precision. This carbon nanotube liquid dispersion contains at least a solvent and a carbon nanotube complex in which a conjugated polymer is attached to at least a portion of the surface of a composite carbon nanotube, wherein the conjugated polymer has a side chain represented by general formula (1), and the solvent is a single solvent or a solvent mixture and includes a solvent having a viscosity of 5-40 cP and a boiling point of 150-290°C or a vapor pressure of 0.9-500 Pa. (In general formula (1), R1 represents an alkylene group or a cycloalkylene group, X represents a single bond, an alkenylene group, or the like, and A represents a hydroxyl group, an alkylsulfanyl group, or the like.)
