The application of ink-jet printing technologies suitable for the direct writing of complex patterns requires ink-jet printable inks with appropriate properties. Good ink-jet printability and particle-dispersion stability of inks are necessary for ink-jet printing in a particle-included dispersion system. This study investigates the effects of the rheological properties of silver nanoparticle conductive inks with different dispersion states on printability and ink stability. In addition, the electrical properties (i.e., resistivity) of films that were annealed at temperatures ranging from 300 °C to 500 °C and fabricated by three inks with different dispersion states were measured, revealing that film conductivity was strongly related to the dispersion state of the ink.
