  • Publication number: 20130029034
    Abstract: A process for producing silver nanoparticles includes receiving a first mixture comprising a silver salt, an organoamine, a first solvent, and a second solvent; and reacting the first mixture with a reducing agent solution to form organoamine-stabilized silver nanoparticles. The polarity index of the first solvent is less than 3.0, and the polarity index of the second solvent is higher than 3.0. The nanoparticles are more dispersible or soluble in the first solvent.
