Silver (Ag) metal-plated nanofibers were prepared from nylon 6/silver iodide (AgI) composite nanofibers. Pristine nylon 6 nanofibers formed by electrospinning were iodinated with an iodine-potassium iodide aqueous solution and subsequently immersed in a silver nitrate solution to form AgI particles in the nanofiber matrix. After the reduction of AgI to Ag metal, electroless Ag plating was carried out on the composite nanofibers. Here, the Ag particles reduced from AgI function as autocatalyst particles as well as an anchor for the metal plated layer. SEM observations showed that a Ag plated layer formed on each nanofiber. The surface electrical conductivity of the Ag-plated nanofibers was determined to be ca. 1 x 10-1 ohm cm-2. After sonication for 30 min, the Ag-plated layer remained intact and the conductivity of the samples was retained, indicating good interfacial adhesion between the nanofiber surface and metal plated layer.
