Abstract: Improved conductive ink compositions and methods of making and using the conductive ink compositions are provided. The improved conductive ink compositions include a silver complex formed by mixing a silver carboxylate, specifically a silver decanoate isomer, and at least one dissolving agent, in particular where the at least one dissolving agent comprises a terpene, a terpenoid, or a combination thereof. The silver carboxylate of the subject ink compositions is decarboxylated at a temperature of 250° C. or less. The conductive ink compositions preferably further comprise a non-acid stabilizer and optionally further comprise an acid stabilizer and/or an adhesion promoter. Methods of making conductive structures, including methods wherein the disclosed compositions are applied to a suitable substrate by various techniques, are also provided.

Abstract: Conductive ink compositions comprising gold complexes are provided. Also provided are methods of preparing the conductive ink compositions, methods of forming conductive structures from the conductive ink compositions, and structures formed from the conductive ink compositions. The conductive ink compositions preferably comprise a gold metal, an organophosphite ligand, and a solvent and are preferably particle-free. The conductive ink compositions can be used to form conductive structures comprising gold, for example by inkjet or other printing methods, at temperatures of 400° C. or less. Such conductive structures can be formed on a variety of substrates.

Abstract: Improved conductive ink compositions are provided. The improved conductive ink compositions include a silver complex formed by mixing a silver carboxy late, specifically a silver decanoate isomer, and at least one dissolving agent, in particular where the at least one dissolving agent comprises a terpene, a terpenoid; or a combination thereof. The silver carboxy late of the subject ink compositions is decarboxylated at a temperature of 250° C. or less, optionally in the presence of an adhesion promoter and/or an acid stabilizer, to form a conductive structure. Methods of making conductive structures, including methods wherein the disclosed compositions are applied to a substrate by various techniques, are also provided.

Abstract: A cellulosic substrate-based device is described, including a cellulosic substrate comprising a functionalized surface covalently functionalized by a chemical moiety in an amount sufficient to provide an omniphobic or hydrophobic surface; and a material printed on the functionalized surface, wherein the printed material has a line edge roughness of less than about 15 ?m and/or a line lateral resolution of less than about 50 ?m.
