Document Type and Number:
WIPO Patent Application WO/2019/065461
Kind Code:
A1
Abstract:
[Problem] To produce wires having a particularly large average length and a large average aspect ratio when synthesizing fine silver nanowires by an alcohol solvent reduction method. [Solution] A silver nanowire production method comprising a step in which silver is reductively precipitated into the form of a wire in an alcohol solvent in which a silver compound and an organic protective agent have been dissolved, said method being characterized in that a polymer having a vinyl pyrrolidone structural unit is used as the organic protective agent and the reductive precipitation is performed in a solution obtained by dissolving methyl-t-butyl ether in the alcohol solvent at a concentration of 0.3-25.0 mmol/L.
