Reactive ink chemistries offer unique solutions to numerous issues in printed electronics and have the potential to address other areas in additive manufacturing as well where dense, pure films are required. While the initial work on reactive silver ink showed high conductivities, it was limited to relatively low viscosities that were particularly well-suited for inkjet or aerosol printing. By tuning these complexes one can increase the viscosity by several orders of magnitude without the use of polymers. This allows the user to see the same conductivities and film performance as the originally proposed chemistry but gives access to a wider breadth of deposition techniques. Furthermore, a wider material palette can be accessed by tuning the complexes for various metals resulting in a robust formulation strategy for numerous applications.
