Abstract

Silver neodecanoate salt is both light and heat sensitive, and is suitable for inkjet printing when dissolved in organic solvents. We have studied the electrical properties of inkjet printed silver samples, derived from silver neodecanoate ink, and investigated the influence of ultra violet light (UV) treatment on the silver samples before air oven cured at variety length of time. In addition we have studied the influence of thermal pre-treatment on the printed samples. Thermally cured printed silver squares show minimum resistivity of approximately 3x bulk silver. The microstructure shows an interconnected network of silver nanoparticles after curing. The resistance of the printed pads are shown to relate to the connectivity of the resulting sintered nanoparticle network as measured by the ratio of the sintered neck diameter to the original particle diameter.
