Direct Write (DW) manufacturing methods can precisely print microcircuits, computer chips, and other electronics. Currently, electronics printed by DW methods have focused on silver and gold components due to their high conductivity. However, the high cost of these materials has led to the investigation of other more economical metals, such as copper. For Cu, we have successfully generated Cu nanoinks (N-inks) that produce high quality components. Following this success, we have expanded our research to other first row transition nanometals due to their diverse properties. In particular, we have synthesized nanoiron metal particles, converted them to Fe N-inks, printed traces by DW methods, and tested the electronic and magnetic properties. To generate the Fe nanometals, a variety of tailored precursors such as metal alkoxides, amides, alkyls, as well as commercially available compounds (i.e., metal carbonyls) were evaluated as useful precursors to high quality (size, shape, crystallinity) Fe nanoparticles for production of tailored Fe N-inks. The precursor synthesis, nanomaterial processing, Fe N-ink formulation, magnetic properties, and final electronic properties of printed metals will be presented.<br/><br/><br/>Sandia National Laboratories is a multi-mission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC., a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525.
