US 10,329,444 B2 · Nickel inks and oxidation resistant and conductive coatings

Abstract

A conductive ink may include a nickel component, a polycarboxylic acid component, and a polyol component, the polycarboxylic acid component and the polyol component being reactable to form a polyester component. The polyester component may be formed in situ in the conductive ink from a polyol component and a polycarboxylic acid component. The conductive ink may include a carbon component. The conductive ink may include an additive component. The conductive ink may include nickel flakes, graphene flakes, glutaric acid, and ethylene glycol. The conductive ink may be printed (e.g., screen printed) on a substrate and cured to form a conductive film. A conductive film may include a nickel component and a polyester component.
