Title:
METHOD FOR PRODUCING SILVER NANOWIRE INK, SILVER NANOWIRE INK AND TRANSPARENT CONDUCTIVE COATING FILM
Document Type and Number:
WIPO Patent Application WO/2018/164166
Kind Code:
A1
Abstract:
[Problem] To provide: a method for producing nanowires having high industrial utility; and a conductive film which has both high transparency and high conductivity.
[Solution] A method for producing a silver nanowire ink, in which urethane resin particles that are formed from a urethane resin having a degree of elongation of less than 500% and have an average particle diameter of 200 nm or less are mixed into a silver nanowire dispersion liquid. The urethane resin has an average of the 100% modulus values (100% Mo), for example, of 6.0 MPa or more. The content of a urethane resin colloid or a urethane resin emulsion relative to the total mass of the silver nanowire ink may be set to 0.01-2.0% by mass in terms of urethane. It is preferable that the silver content relative to the total mass of the silver nanowire ink is set to 0.01-2.0% by mass. It is preferable that the content of a viscosity regulator relative to the total mass of the silver nanowire ink is set to 0.01-2.0% by mass.
