Abstract
The present invention provides for a relatively simple method to decrease the electrical resistivity of conductive adhesives by in-situ nanoparticle formation and sintering using a reducing agent. The reducing agent was found to cause sintering within the conductive adhesive by facilitating the reduction of the silver salts of fatty acids on the surface of silver flakes, leading to the formation of nano-/submicron-silver necks. These silver necks bridge neighboring silver flakes, decreasing the contact resistance between flakes within the conductive adhesives. The reducing agent also removes at least a portion of the lubricant commonly found on silver flakes used in conductive adhesives, thus reducing the tunneling resistance between the silver flakes.
