A simulation and experimental study on packing of nanoinks to attain better conductivity

Abstract

A simulation and experimental study on the packing of nanoinks has been carried out. Simulation predicted that the packing of two different sized monodispersed colloids would results in a more densely packed structure than a single sized monodispered colloid alone. The simulated results were confirmed by conducting experiments with two different sized-monodispersed silver colloids. A binary sized ink was printed in a rectangular pattern using a direct write method system and then the final pattern was sintered. The pattern was confirmed to be highly conductive and the final conductivity obtained from this pattern gave 47% of the bulk conductivity of silver.
