Provided is a method for manufacturing a nanowire with a core-shell structure including the following steps: (step 1) manufacturing a mixed solution by manufacturing a dispersion solution including nanosilver wire and then adding a reducing agent and a pH adjusting agent to the dispersion solution; and (step 2) coating the surface of the nanosilver wire with gold by injecting precursors of gold (Au) into the mixed solution manufactured by step 1. According to the present invention, the method for manufacturing a nanowire with a core-shell structure can form a fine shell on the surface of the nanosilver wire in the solution in an easy manner and can minimize a consumption amount of gold by coating the surface with a fine and thin gold film. In addition, breakage of the nanosilver wire can be ultimately prevented by preventing migration of the nanosilver wire, which is a core. Furthermore, oxidation stability and chemical stability of the nanosilver wire can be enhanced. Moreover, when the nanowire with a core-shell structure manufactured by the method of the present invention is applied to a device, performance of the device can be maintained for a long period of time. |
