Metal nanowires with high linearity, method for producing the metal nanowires and transparent conductive film including the metal nanowires

A method for producing metal nanowires with high linearity, the method comprising:

• (a) mixing a polymeric material and a reducing agent in a solvent and stirring the mixture to prepare a first mixed solution;
• (b) adding a first metal salt to the first mixed solution to prepare a second mixed solution containing metal seeds formed therein;
• and
• (c) adding a second metal salt to the second mixed solution and reacting to form metal nanowires,
• wherein the solvent is a mixture of distilled water and at least one solvent selected from diethanolamine and triethanolamine,
• the polymeric material is selected from polymethyl methacrylate, polyvinyl butyral, polyethyl methacrylate and mixtures thereof, each of the polymers having a molecular weight of 800,000 to 2,000,000,
• the reducing agent is selected from sodium borohydride, sodium hydroxide, sodium phosphinate monohydrate, ammonium hydroxide, potassium bromide, cetyltrimethylammonium bromide and mixtures thereof, and
• the first metal salt and the second metal salt are each independently an acetate, nitrate, chloride or sulfate salt comprising a metal selected from Cu and Ni;
• and the first metal salt and the second metal salt are different salts of the same metal.
