The purpose of the present invention is to provide a method for preparing a silver-plated conductive long fiber and a silver-plated conductive long fiber prepared thereby. For achieving the purpose, the present invention provides a method for preparing a silver-plated conductive long fiber, comprising the steps of: dissolving poly(amide-co-imide) and poly(trimellitic anhydride chloride-co-4,4′-methylenedianiline) at a weight ratio of 4.5:5.5 to 5.5:4.5 in a solvent, followed by mixing (step 1); electrospining the mixture solution obtained in step 1 to prepare a long fiber (step 2); and forming silver nanoparticles on a surface of the long fiber obtained in step 2 (step 3). According to the present invention, the silver-plated conductive long fiber is prepared by using poly(amide-co-imide) and poly(trimellitic anhydride chloride-co-4,4′-methylenedianiline) as raw materials to prepare the long fiber, and then plating the prepared long fiber with silver, so that the surface of the long fiber is activated by a polyethylene glycol solution, thereby uniformly plating the long fiber with the silver nanoparticles. The long fiber prepared according to the present invention can exhibit excellent conductiviety and thus can be used as a material for an electrode, since the silver nanoparticles are plated on the surface of the long fiber. |
