In the present study, silver nanoparticles were produced by hydrazine hydrate and oleylamine/oleic acid systems in order to investigate the effects of reducing agents with different strengths on the reduction mechanism. Particle size and size distribution of silver particles produced by slow reducing system were studied in detail by using transmission electron microscopy (TEM), X-Ray Diffraction (XRD), photon correlation spectroscopy (PCS), and surface plasmon resonance spectroscopy (SPR). Finally, reduction mechanism by oleylamine and oleic acid system was clarified and particles with average diameter of 2.7 nm were produced. Nano-sized particles were then placed at the center of the polymer fibers by coaxial electrospinning and nanocable like structures were produced. SEM and TEM were used for the characterization of these cables.
