In this study, conductive metal films of copper (Cu) and silver (Ag) were deposited onto the polyamide 6 nanofiber nonwoven substrates at room temperature. Atomic force microscopy (AFM) and Scanning Electron Microscopy
(ESEM) were employed to study the topography and chemical composition of the nanofibers, respectively. The AFM results indicate a significant change in the morphology of the fibers before and after the sputter coating of the metallic film.
A full energy dispersive x-ray analysis (EDX) mounted on the SEM was also used to detect the elemental composition of the functional nanofibers. EDX examination reveals the change in the chemical compositions of the nanofiber
surfaces. The surface conductivity properties of the fibers were also investigated. The nanofiber nonwovens sputtered with metallic coating showed significant improvement in surface electrical properties.
