Claim Text:
1. A method of manufacturing metal nanowire, comprising: mixing a metal salt, an ionic liquid and a reducing solvent and allowing them to react, so that a metal element produced from the metal salt by a polyol reduction interacts with the ionic liquid and thus is manufactured in nanowire form, wherein the ionic liquid is a compound composed of an organic cation having an imidazolium group and an organic or inorganic anion, and is selected from the group consisting of a monomeric ionic liquid represented by Formula 1 below and a polymeric ionic liquid represented by Formula 2 below: wherein R wherein the monomeric ionic liquid comprises either or both of a cation and an anion, the cation being selected from the group consisting of 1,3-dimethylimidazolium, 1,3-diethylimidazolium, 1-ethyl-3-methylimidazolium, 1-butyl-3-methylimidazolium, 1-hexyl-3-methylimidazolium, 1-octyl-3-methylimidazolium, 1-decyl-3-methylimidazolium, 1-dodecyl-3-methylimidazolium and 1-tetradecyl-3-methylimidazolium, and the anion being methylsulfate, wherein the polymeric ionic liquid comprises either or both of a cation and an anion, the cation being selected from the group consisting of poly(l-vinyl-3-alkylimidazolium), poly(1-allyl-3-alkylimidazolium) and poly(1-(meth)acryloyloxy-3-alkylimidazolium), and the anion being methylsulfate, and wherein the metal nanowire has a length-to-diameter ratio of at least 50.
