Aqueous-based dispersions of metal nanoparticles for use in conductive inks.

Abstract:

The invention relates to a method for prepg. an aq.-based dispersion of metal nanoparticles comprising: (a) pre-reducing a metal salt suspension by a H2O sol. polymer capable of metal redn. to form a metal nuclei; and (b) adding a chem. reducer to form metal nanoparticles in dispersion. The invention further relates to aq.-based dispersions of metal nanoparticles, and to compns. such as inks comprising such dispersions. [on SciFinder(R)]
