<p>The present invention relates to a method for producing and separating a silver nanoparticle in the nanowire shape; and a conductive film including a silver nanowire manufactured by the same method. The method includes the steps of: (a) providing a silver nanoparticle mixture including silver, chloride ions (Cl-), and nitrate ion (NO_3-) by producing a solvent mixture, obtained by mixing polyol and a polymer, and adding silver salt, chloride and nitrate into the solvent mixture; (b) providing a ketone mixture by mixing the silver nanoparticle mixture with ketone; (c) removing non-linear particles by firstly filtrating the ketone mixture with a first filtering means; (d) providing a water or ethanol mixture by washing the filtrated silver nanowire mixture with water or ethanol; (e) agitating a methanol mixture after producing the methanol mixture by mixing the water or ethanol mixture with methanol; and (f) separating the methanol mixture into nanowires in the predetermined length or longer and nanowires in the predetermined length or shorter by secondly filtrating the methanol mixture with a second filtering means. According to the present invention, the method can rapidly and efficiently manufacture a silver nanowire with a constant length, thereby enabling application of a silver nanowire to suit appropriate applications by manufacturing a silver nanowire per length. And a conductive film including a silver nanowire with a constant length can be used as a transparent electrode with low sheet resistance and high transmittance.</p> |
