Production of silver nanowires from silver nanoparticles by thermal treatment

Abstract EN

Silver nanowires (Ag NWs) have been attracted much attention in recent years .view of the extensive its use in various fields.

Ag NWs were successfully prepared by two steps firstly electrochemical method and heating secondly silver nanoparticles colloidal solution at different temperature.

The optical results show that the position of the plasmon absorption peak depends on the particle size and shape and the adsorption of surfactant to the particle surface.

It was noticed that the plasmon absorption peak shifts toward shorter wavelengths (blue shift) as increased temperature.SEM result appeared that silver nanoparticles transformed to Silver nanowires by heating.

XRD results explained that the intensity of peak at 64.46° was increased as heating increase much higher at 38.18° which indicted wire growth .

The results zeta potential showed that all samples preparation shown across all the zeta potential tests were negative .
