We
successfully developed a novel method for room-temperature (RT)
sintering of silver nanoparticle (Ag NP) paste under an air atmosphere.
A nonaqueous paste consisting of tri-<i>n</i>-octylphosphine
oxide (TOPO) and TOPO-capped Ag NPs was prepared by the ligand exchange
method. Then the paste was cast on the PET substrate and sintered
at RT by dipping into an organic solvent containing a sintering agent.
The experimental conditions such as sintering agent, dipping time,
dipping solvent, and ligand of Ag NP were examined for optimizing
the RT sintering. The electrical resistivity of the Ag thin films
obtained in this study was about 10<sup>–5</sup> Ω m,
which was comparable to that of the Ag thin film prepared by the thermal
sintering. The chemical composition of the Ag thin films characterized
by X-ray photoelectron spectroscopy and X-ray diffraction showed the
formation of pure Ag films.
