In this study, we prepared polymer-protected silver colloids from silver nitrate by reduction with sodium borohydride in aqueous medium and investigated for stability of silver colloid depending on the type of protective polymer. The particle sizes and size distributions of the silver nanoparticles were determined by transmission electron microscopy (TEM), and UV-vis spectroscopy was employed for dispersion stability and additional characterization. Finally, the ability of each protective polymer to stabilize metal colloids were investigated and compared to one another. |
