摘要： A method for producing silver nanowires, containing reduction-precipitating silver in the form of wire in an alcohol solvent having dissolved therein a silver compound, the deposition being performed in the alcohol solvent having dissolved therein a chloride, a bromide, an alkali metal hydroxide, an aluminum salt, and an organic protective agent, the molar ratio Al/OH of the total Al amount of the aluminum salt dissolved in the solvent and the total hydroxide ion amount of the alkali metal hydroxide dissolved therein being from 0.01 to 0.40, the molar ratio OH/Ag of the total hydroxide ion amount of the alkali metal hydroxide dissolved in the solvent and the total Ag amount of the silver compound dissolved therein being from 0.005 to 0.50.

摘要： Silver nanowires having a thin and long shape that exhibit excellent dispersibility in an aqueous solvent having an alcohol added thereto are provided by silver nanowires having an average diameter of 50 nm or less and an average length of 10 μm or more, covered with a copolymer of a maleimide-based monomer and vinylpyrrolidone. The silver nanowires can be produced by a method for producing silver nanowires, containing reductively depositing silver in a wire form in an alcohol solvent having dissolved therein a silver compound, the deposition being performed in the solvent having dissolved therein a copolymer of a maleimide-based monomer and vinylpyrrolidone.
