AbstractSilver neodecanoate is sensitive to both ultra violet light (UV) and heat, and is a good inkjet printing precursor when dissolved in xylene. We have studied the electrical properties of inkjet printed silver samples, derived from silver neodecanoate ink, and investigated the influence of UV treatment before thermal curing the silver samples. In addition we have studied the influence of thermal pre-treatment on the printed samples. Thermally cured printed tracks and pads show minimum resistivity of approximately 3 x bulk silver. Their microstructure shows that the silver salt has converted to an interconnected network of silver nanoparticles after curing. The resistance of the printed tracks 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.
