Properties, Storage, and Cautions
Copper nanoparticles are highly reactive and flammable, and therefore should be handled with care. Rapid movements and vibrations must be avoided.
Nanopowder should be kept away from sunlight, heating sources, moisture, and impacts. Coagulation of the particles is a serious problem, so the nanopowder should be sealed under vacuum and stored in cool, dry conditions. Air contact should be avoided.
Applications
Copper nanoparticles are known for their high electrical conductivity and are primarily used in the electronics industry. They can be utilized in conducting coatings, inks, and pastes; as raw materials for electronic parts; as catalysts for reactions such as methanol production; in microelectronic devices; as additives for lubricants; for wear-resistant coatings; and as sintering additives.
