Abstract

Abstract : Electronic devices are components used in information and communications technology (ICT) where information is encoded in the electronic charge channel. Among them, those manufactured through digital printing, benefited from a tremendous research effort for the creation of a palette of functionalities provided by solution processed materials, to achieve dielectric, metallic, and semiconductive behavior. The degree of metallicity of available printable inks very seldom goes below the threshold of 200 m⇆/⬜, which is fundamental for the fabrication of high‐quality conductors. Here we describe the formulation of an ink based on a mixture of diamine silver(I) carbonate, ammonium formate, and polyols, providing several physicochemical characterizations and describing the process leading to a sheet resistance below 200 m⇆/⬜ after annealing at 120 °C for 5 minutes. Abstract : An Ag‐based metal‐organic water‐soluble ink was realized, which could be effectively exploited for inkjet printing of conductive patterns on polymer substrates. Only a slight low‐temperature post‐annealing is needed for achieving an ultimate sheet resistance below 200 m⇆/⬜.
