A Water‐Soluble Ink Based on Diamine Silver(I) Carbonate, Ammonium Formate, and Polyols for Inkjet Printing of Conductive Patterns

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.

Application of Zinc-Silver Impregnated Activated Carbons in Removal of Lead(II) and Mercury(II) Compounds from Groundwater

“…Silver and copper can also be deposited on activated carbon's surface. First, a diamine silver(I) carbonate complex is formed [16], and afterwards, as a result of thermal decomposition, metallic silver particles, silver(I) oxide, carbon dioxide and ammonia are obtained. The concentrations of each metal ion are shown in the table (Table 1).…”

Current Developments in Conductive Nano-Inks for Flexible and Wearable Electronics

“…Inkjet printing has gained popularity in recent decades as a unique technology that has piqued the interest of the pharmaceutical industry as a viable approach for producing tailored and configurable dosage forms to deliver medications. Inkjet printing technology is widely used in the formation of various components for electronic equipment: light-emitting diodes, small sized antenna systems, selective gas sensor, LCD displays, solar energy converters, FET, etc [19]. Metallic particles or carbon particles are commonly used in conductive ink formulations [20].…”
