Properties, Storage and Cautions
Copper nanoparticles are highly reactive and flammable; therefore, they must be handled with care. Rapid movements and vibrations should be avoided.
Nanopowder must be kept away from sunlight, heat sources, moisture, and physical impacts. Coagulation is a significant concern, so the powder should be sealed under vacuum and stored in cool, dry conditions. Air exposure should be avoided.
Applications
Copper nanoparticles exhibit high electrical conductivity and are widely used in the electronics industry. They are suitable for conducting coatings, inks, and pastes; as raw materials for electronic components; as catalysts for reactions such as methanol production; in microelectronic devices; as additives for lubricants; for wear-resistant coatings; and as sintering additives.
