Properties, Storage and Cautions
Copper nanoparticles are highly reactive and flammable and must be handled with care. Rapid movements and vibrations should be avoided. The nanopowder must be stored away from sunlight, heat, moisture, and impacts. Due to the tendency for particle coagulation, it should be vacuum-sealed and kept in cool, dry conditions with minimal air exposure.
Applications
Copper nanoparticles are known for their high electrical conductivity and are widely used in the electronics industry. They can be incorporated into conducting coatings, inks, and pastes; used as raw materials for electronic components; applied in catalytic reactions such as methanol production; and utilized in microelectronic devices, lubricant additives, wear-resistant coatings, and sintering additives.
