We have prepared silver nanoparticles capped by oleic acid via solvent exchange method. AgNO3 was reduced by NaBH4 to produce Ag nanoparticles, and oleic acid was used as stabilizer. Hydrophobic silver nanoparticles were prepared by adding H3PO4 to induce phase transfer in hydrosol-organic solvent. The prepared silver nanoparticls was characterized by X-ray Diffraction (XRD), Fourier Transfer Infrared Spectrometer (FTIR), Electrophoretic Lighting Scattering (ELS), Scanning electron microscopy (SEM) and Turbiscan. The particle size and the dispersion stability were dependent on pH of solution. |
