Direct-Write (DW)technology such as Aerosol Jet (AJ) printing, encompasses non-contact deposition methods that employ novel formulation of nanoparticle based inks, termed N-inks, and are used to fabricate electronic components such as, resistors, transistors, and capacitors. As DW processes continue to expand into printed electron components and circuitry, the development of new and more versatile N-inks is critical. Coinage nanometals (Cuo, Ago, and Auo) have generally been investigated for printed electronic applications; however, to further evolve these processes, novel magnetic nanomaterials such as the low Z metals (Mn0, Fe0, Ni0, and Co0), which can be converted to high quality N-inks must be developed. While routes to these metal have been widely reported, most employ a commercially available source, which greatly limits the properties of the nanomaterials that can be generated. For this work in-house synthesized metal amides, alkyls, and alkoxides were synthesized and then used to generate nanomaterials with tailored physical properties (i.e., crystalline phase, size, and morphology). In particular, a series of M(II) aryloxide [M(OAr)2(solv)x] (M = Ni, Co, Fe, Mn) were synthesized and evaluated for precursor impact on final properties. The high quality nanomaterials produced were converted to N-inks using an antioxidant, dispersant, and the optimum solvent and printed using the Aerosol Jet method. In addition, combinations of these and other precursors led to novel metal-alloys and their potential in 3D manufacturing is presented.
