Abstract: A method of making a conductive article includes providing a substrate having a surface with one or more micro-channels having a width of less than 12 ?m. A composition is provided over the substrate and in the one or more micro-channels. The composition includes water and silver nanoparticles dispersed in the water and he weight percentage of silver in the composition is greater than 70% and the viscosity of the composition is in a range from 10 to 10,000 centipoise. The composition is removed from the surface of the substrate. The composition provided in the micro-channels is dried and converted to form one or more electrically conductive micro-wires.

Abstract: A conductive article includes a metal nanoparticle composition formed on a substrate. The metal nanoparticle composition includes silver nanoparticles and a polymer having both carboxylic acid and sulfonic acid groups. The weight ratio of the polymer to silver is 0.0005 to 0.04.

Abstract: A method of making a conductive article includes depositing on a substrate a metal nanoparticle composition having water, silver nanoparticles dispersed in the water and a water-soluble polymer having both carboxylic acid and sulfonic acid groups. The weight percentage of silver in the composition is greater than 10%. The metal nanoparticle composition is dried. The dried metal nanoparticle composition is converted to improve the electrical conductivity of the dried metal nanoparticle composition.
