Abstract

We report on the substitution of silver nanoparticles' inks by silver microparticle dispersions as a material for the production of printable silver tracks by laser melting. This approach is promising, because it helps to reduce the production costs of such silver tracks. Though silver dispersions used as materials for laser melting mostly contain polyvinylpyrrolidone as a stabilizer, which results in the appearance of an undesired balling effect of silver during laser melting, the authors test stabilizers differing in molecular weight and functionality. The resulting differences in colloidal and physicochemical properties are investigated and related to the final silver layer quality.
