Molybdenum and Tungsten Metal Organic Decomposition Complex Synthesis and Characterization

Abstract:
Printing technologies have transitioned, in recent years, from text-on-paper to high speed and roll-to-roll fabrication of low cost electronic devices and sensors on a variety of flexible and 3D form factors. Currently, 3D printing is used to create a variety of objects out of different materials ranging from silica to plastics to metals. In the case of metals, however, 3D printing is limited to softer metals which have lower processing temperatures; therefore, lack the necessary mechanical performance requirements. To overcome this limitation, research into metal delivery in a precursor form continues to expand on the number of accessible metals. Metal organic decomposition (MOD) complexes are precursor metal solutions used to deposit metals in 2D and 3D forms using a reduction chemistry pathway. Most MOD synthetic complex efforts have focused on conductive metal inks derived from the Group 10 and 11 transition metals; such as silver, copper and nickel, due to their favorably low reduction potentials and relevance to electronic applications. Availability of more mechanically robust metals and metal alloys remain elusive. Possible MOD metal candidates would involve the elements in the early transition metal group series. A synthetic pathway for the development of a tungsten and molybdenum MOD complex will discussed. Tungsten and molybdenum are of interest because they are two of the hardest metals on earth. Once a tungsten and molybdenum MOD complex and ink are developed, it may be possible to 3D fabricate durable mechanical parts both on earth and in space.
