Morphology and redispersibility of silver nanoparticles prepared by chemical reduction

Abstract

Abstract In the present work we fabricated and investigated colloidal Ag nanoparticles (NPs). The NPs were synthesized by the chemical reduction method of Ag2SO4 using NaBH4 in the presence of different surfactants. Morphological properties of synthesized colloidal Ag-NPs were studied by ultraviolet-visible (UV-vis) spectroscopy and dynamic light scattering (DLS). Average NP size varied in the range from 3 to 15 nm. Redispersibility of dried NPs with various stabilizers was also investigated and recovered that fish oil is effective stabilizer.
