Abstract

The present invention relates to a method for manufacturing copper nanoparticles, in particular, to a method for manufacturing copper nanoparticles, wherein the method includes preparing a mixture solution including a copper salt, a dispersing agent, a reducing agent and an organic solvent; raising temperature of the mixture solution up to 30-50° C. and agitating; irradiating the mixture solution with microwaves; and obtaining the copper nanoparticles by lowering temperature of the mixture solution. According to the present invention, several tens of nm of copper nanoparticles having a narrow particle size distribution and good dispersibility can be synthesized in mass production.
