METHOD FOR PRODUCING COPPER NANOPARTICLES CAPABLE OF BEING FIRED AT ATMOSPHERIC PRESSURE

摘要

The present invention relates to a method for producing copper nanoparticles capable of being fired at atmospheric pressure. The method of the present invention involves adding strongly basic low nucleophilic organic amines or organic diamines to a copper precursor solution, and performing a reduction process on the resultant mixture to produce copper nanoparticles. The thus-produced copper nanoparticles are small and uniform, and are not oxidized even when being fired at atmospheric pressure in which partial pressure of oxygen exists, thus exhibiting superior electrical conductivity, and can be valuably used as materials for metal ink in lieu of expensive silver particles.
