Title:
METHOD FOR CONCENTRATING METAL NANOWIRE DISPERSION, AND METHOD FOR PREPARING METAL NANOWIRE INK
Document Type and Number:
Japanese Patent JP2015206081
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for concentrating a metal nanowire dispersion, in which the concentration of the metal nanowire in the metal nanowire dispersion can be made higher by a simple step without aggregating or damaging the metal nanowire.SOLUTION: The metal nanowire is produced by a polyol reduction method or the like and has 10-90 nm length (diameter) in the short axial direction and 1-100 μm length in the long axial direction. The metal nanowire dispersion, which is prepared by dispersing the metal nanowire in a solvent having high dispersibility, is made to flow through a filter, so that an input ratio (the amount of the metal nanowire dispersion to be passed through an inlet of the filter to be used for filtration)/(the amount of the metal nanowire dispersion to be concentrated) becomes 10 or smaller, and is concentrated by crossflow filtration.
