Abstract

The generation of fine relics of metallic materials from precursor suspensions is of significant current interest as it holds the key to the fabrication of display and printed circuit board. Some novel printing methods of depositing metallic particles have been suggested in recent years. When a nanoparticle suspension is supplied to a nozzle at a low flow rate and when the interface between air and the liquid is charged to a sufficiently high electrical potential, the liquid meniscus takes the form of a stable cone, whose apex emits a microscopic jet. This is called as cone-jet mode. In our experiments, two silver nanoparticle (3-7 nm, below 25 nm) suspensions flowing through a nozzle were subjected to electro-hydrodynamic printing in the cone-jet mode. The patterns deposited on polyimide film were subsequently post-processed to allow for complete evaporation of the carrier and for curing of the nanoparticles. The properties (feature size, thickness, resistance) of patterned silver line were as measured by surface profiler, confocal laser scanning microscope, and I-V meter. Pattern after post process exhibited feature as fine as 20 μm wide and 0.29 μm thick with resistivity of 13 μΩcm.
