Silver nanowires (AgNWs) have been successfully synthesized by using polyol process. In this study, the synthesis AgNWs using ethylene glycol (EG) as solvent and reductant, silver nitrate (AgNO3) as the metal precursors, and polyvinyl alcohol (PVA) as a capping agent and stabilizer without adding chloride ions. The synthesis AgNWs was done by varying the stirring rate about 125, 350, 500, 700, and 1100 rpm. The scanning electron microscopy (SEM) showed that the AgNWs optimally formed at a stirring rate of 350 rpm with a diameter of (190 ± 40) nm and a length about (70 ± 20) µm. The silver nanorods (AgNRs) formed with diameter and length about (500 ± 20) nm and (20 ± 10) µm for stirring rate of 500 rpm, and (700 ± 30) nm and (20 ± 5) µm for 700 rpm. For the stirring rate of 125 and 1100 rpm only produced silver particles (AgNPs) with a diameter of 2 to 3 µm. The X-ray diffraction (XRD) and transmission electron microscopy (TEM) showed AgNWs has a high crystalline with face-center-cubic (fcc) structures. The UV-vis spectra of AgNWs shows that the absorbance peaks at a wavelength of 358 and 380 nm. PVA can be used as a capping agent and stabilizer for the synthesis AgNWs and AgNRs with high aspect ratio.
