Abstract
A metallic nanoparticle composition includes metallic nanoparticles and a non-aqueous polar protic solvent. The non-aqueous polar protic solvent has two hydroxyl groups, a boiling point of at least 280° C. at 760 mm Hg, and a viscosity in a range of 45 cP to 65 cP at 20° C. Polyvinylpyrrolidone (PVP) is present on the metallic nanoparticle surfaces. A concentration of metals in the metallic nanoparticle composition is in a range of 60 wt % to 90 wt % and a concentration, in aggregate, of solvents having a boiling point of less than 280° C. at 760 mm Hg in the metallic nanoparticle composition does not exceed 3 wt %.
