Directing Write (DW) technologies are emerging as a highly effective additive manufacturing technique in the development of printed electronic components and circuitry. Non-contact DW deposition methods, such as Aerosol Jet (AJ) printing, employ novel formulation of nanoparticle-based inks to fabricate the desired electronic components including, resistors, transistors, and capacitors. Improvements in the properties and novel materials for these nanoinks are critical for the continued development of DW and AJ methods. Our recent efforts have focused on the development of an anhydrous route to the synthesis of metal (Cu, Ni, Fe) nanoparticles (NP) through a solution precipitation route using in-house metal alklyl precursors injected into a hot hexadecylamine solution (300 degrees celsius). As this work expands, other precursors are also being explored, including amido and alkoxide based precursors. In particular, we are interested in producing nanoinks of Nio using nickel mesityl ([Ni(Mes)2]) or nickel amide ([Ni[N(SiMe3)2]2) as the main precursors. In addition, the synthesis and characterization of a series of Ni(II) aryloxide [Ni(OAr)2(py)x] were realized and then investigated for the production of Ni NPs. The utility of these compounds and the properties of the final materials developed for DW technologies will be presented.
