Properties, Storage and Cautions
Copper nanoparticles are highly reactive and flammable and must be handled carefully. Rapid movements and vibrations should be avoided. The nanopowder should be kept away from sunlight, heat, moisture, and impacts. Because particle coagulation is a significant issue, the powder should be vacuum-sealed and stored in cool, dry conditions with minimal air exposure.
Applications
Copper nanoparticles are valued for their high electrical conductivity, making them widely used in the electronics industry. They are applied in conductive coatings, inks and pastes, electronic component fabrication, catalysis (such as in methanol production), microelectronic devices, lubricant additives, wear-resistant coatings, and as sintering additives.
