Title:
METHOD FOR PRODUCING SILVER NANOWIRE, SILVER NANOWIRE, DISPERSION, AND TRANSPARENT CONDUCTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2018/110157
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a silver nanowire, the method being capable of shifting the absorption maximum of a plasmon absorption band to the short wavelength side without reducing the diameter of the wire. [Solution] The present invention provides a method for producing a silver nanowire, the method comprising a step for heating a mixed solution of a silver nanowire dispersion and metal ions of a transition metal other than silver, and reducing the metal ions to precipitate masses of the transition metal at discrete locations on the surface of the silver nanowire. A silver nanowire thus produced has metal clumps disposed at discrete locations in the longitudinal direction, and has an absorption maximum shifted to the short wavelength side in a plasmon absorption band.
