PREPARING METHOD OF COPPER NONOPARTICLES

摘要

PURPOSE: A method for producing copper nanoparticles is provided to adjust the size of copper nanoparticles to a desired level by using an ionic liquid. CONSTITUTION: A method for producing copper nanoparticles comprises the following steps of: putting micro-sized copper particles into an ionic liquid and obtaining an ionic liquid/micro-sized copper metal composite; and stirring the ionic liquid/micro-sized copper metal composite and obtaining nano-sized copper particles. The size of the micro-sized copper particles is 1 ~ 5μm. 0.001-0.01 part of copper particle reacts to 1 part of ionic liquid.
