Abstract
A process is described for the synthesis of metallic nanoparticles by chemical reduction of metal salts in the presence of organic ligands capable of binding to the metal particle surfaces and stabilizing them against agglomeration. The resultant nanoparticles or dispersions of the particles can be sintered into highly conductive films or traces at temperatures as low as 80° C. in 10 minutes or less.
