摘要： Silver nanowires coated with, instead of a polymer protective agent such as PVP, an organic protective agent having a smaller molecular weight are provided. The silver nanowires have an average diameter of 100 nm or less and an average length of 5 μm or more, and a thiol having a molecular weight of 75 to 300 is adhered on surfaces of the metal silver. The silver nanowires have a thiol containing one thiol group in the structure adhered thereon. A thiol having only one thiol group (—S—H) in a molecule is a suitable target. Examples thereof include 1-dodecanethiol, 1-decanethiol, 1-octanethiol, 3-mercapto-1,2-propanediol, monoethanolamine thioglycolate, ammonium thioglycolate, and thiomalic acid.

摘要： A production method of silver nanowires exhibits a yield enhancement effect for a protective agent other than PVP. The method for producing silver nanowires includes depositing a silver linear structure, which is referred to as silver nanowires, in an alcohol solvent having a silver compound, a halogen compound, and an organic protective agent dissolved therein. A deposition reaction of silver is performed in a state where aluminum nitrate is further dissolved in the solvent, the total amount of aluminum nitrate dissolved in the solvent being from 0.01 to 0.50 in terms of Al/Ag molar ratio with respect to the total amount of the silver compound. The organic protective agent is, for example, one containing one or more kinds of alkylated PVP and a PVP-PVA graft copolymer.

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.
