Room temperature sintering of Ag nanoparticles by drying solvent

We have successfully developed a new Ag nanoparticle paste which can sinter at room temperature simply by drying the solvent from the paste. A small amount of alkylamine was incorporated into the Ag nanoparticle paste to form protective layers on the nanoparticles. By drying at room temperature, Ag...

Summary:We have successfully developed a new Ag nanoparticle paste which can sinter at room temperature simply by drying the solvent from the paste. A small amount of alkylamine was incorporated into the Ag nanoparticle paste to form protective layers on the nanoparticles. By drying at room temperature, Ag nanoparticles are sintered, resulting in a low resistivity of 4.9 × 10 −6 Ωm. Since the new paste can be sintered even at room temperature without heat treatment, it should prove versatile for applications in electronics wiring.
