Abstract
A conductive ink includes metallic nanoparticles, a polymeric dispersant, and a solvent. The polymeric dispersant may be ionic, non-ionic, or any combination of ionic and non-ionic polymeric dispersants. The solvent may include water, an organic solvent, or any combination thereof. The conductive ink may include a stabilizing agent, an adhesion promoter, a surface tension modifier, a defoaming agent, a leveling additive, a rheology modifier, a wetting agent, an ionic strength modifier, or any combination thereof.
