Provided is a method for producing Ag nanowires, including, heating a precursor solution that includes: an Ag salt; a water-soluble polymer; a surfactant, or a halide of metal ions having a standard reduction potential of &#x2212;0.1 to &#x2212;0.9V as a metal catalyst; and a reduction solvent, to produce the Ag nanowires. According to this method, a time for synthesizing nanowires may be considerably decreased, and an amount of Ag precursor discarded without reaction may be effectively reduced. As a result, the Ag nanowires may be produced with high efficiency and mass-production thereof through a simple scale-up may be successfully achieved.

Method for manufacturing silver nanowires

A button apparatus and a mobile appliance having the same are provided. A button cover plate having button areas forms an external portion of a case of the appliance. The button areas may be flat on the surface of the button cover plate, and include compression bosses on a rear side thereof that contact and manipulate corresponding switches mounted on a substrate. The button cover plate may be seated in a button recess formed on the case. When so arranged, the button apparatus does not project from an outer surface of the mobile appliance, and an external design of the mobile appliance may be varied.
