Abstract
A method of forming a conductive ink silver features on a substrate by printing a silver compound solution and a hydrazine compound reducing agent solution on the surface of a substrate with a printhead. The silver compound solution and the hydrazine compound reducing agent solution are mixed just before, during, or following the printing of both solutions on the surface of the substrate, and the silver compound is then reduced to form conductive silver ink features on the substrate.
Claims23
A method of forming a conductive silver feature on a substrate, the method comprising:
- providing two or more solutions, wherein a first solution is a silver compound solution and a second solution is a reducing agent solution comprised of a hydrazine compound, the reducing agent solution being separate from the silver compound solution;
- printing the silver compound solution and the reducing agent solution onto the substrate with a printhead, wherein just before printing, during printing, or following the printing of both the silver compound solution and the reducing agent solution onto the substrate, the silver compound solution and the reducing agent solution are combined;
- and
- reducing the silver compound to form the printed silver feature on the substrate.
