METHOD FOR PRODUCING SILVER NANOWIRES, SILVER NANOWIRES, SILVER NANOWIRE INK AND TRANSPARENT CONDUCTIVE FILM

摘要

[Problem] To stably produce particularly thin wires in cases where silver nanowires are synthesized by means of an alcohol solvent-based reduction method. [Solution] A method for producing silver nanowires, which comprises a step wherein silver is reduced and precipitated in the form of wires in an alcohol solvent in which a silver compound and an organic protection agent are dissolved. This method for producing silver nanowires is configured such that: a powder which is mainly composed of a polymer having a vinyl pyrrolidone structural unit and contains an acetic acid ester in an amount of from 0.002 to 0.040 mole relative to 1 mole of the polymer is used as a supply source of the organic protection agent; and the silver nanowires have an average diameter D_M of 30 nm or less.
