Abstract
A metal nanoparticle composition includes a bident amine stabilizer associated with an external surface of the metal nanoparticle. A method of forming conductive features on a substrate, providing a solution of dispersed bident amine-stabilized metal nanoparticles, depositing the bident amine-stabilized metal nanoparticle dispersion onto a substrate, and heating the printed substrate to form conductive features on the surface of the substrate.
Claims24
