Physical properties of silver inkjet printed circuits

Abstract

The paper aims to describe methods of dealing with printing issues related to printing metallic nanoparticle inks with micrometric dimensions. The particular focus is on inks containing metal nanoparticles, complexes and metallo-organic compounds that reach acceptable conductivity for the structures. These need to be sintered, the low temperature representing the novel aspect. The work describes the achievement of such electrical tracks with nanoparticle inks printed with commercially available silver ink EMD5603 from Sunchemical. The electrical tracks were printed with different resolutions, on two flexible substrates and the thermal treatment was performed at different temperatures.
