MANUFACTURING METHOD FOR SILVER NANOWIRE, SILVER NANOWIRE, SILVER NANOWIRE INK, AND TRANSPARENT CONDUCTIVE FILM

摘要

[Problem] To stably generate, in particular, a wire with a long average length and a large average aspect, when a thin silver nanowire is synthesized by an alcohol solvent reduction method. [Solution] A manufacturing method for a silver nanowire, comprising a step in which silver is formed into a wire shape by deposition reduction in an alcohol solvent in which a silver compound and an organic protecting agent have been dissolved, wherein the manufacturing method for a silver nanowire is characterized in that a polymer with a vinyl pyrrolidine structural unit is used as the organic protecting agent, an organic acid ester is dissolved in the alcohol solvent to a concentration of 0.1–20.0 mmol/L, and the deposition reduction is made to proceed in this solution.
