Properties, Storage and Cautions
Copper nanoparticles are highly reactive and flammable. They must be handled carefully, avoiding rapid movement, vibration, friction, or impact.
They should be stored:
-
Away from sunlight
-
Away from heat sources
-
In dry, cool conditions
-
Protected from moisture
-
Sealed under vacuum
As nanopowders tend to agglomerate, exposure to air should be minimized.
Applications
Copper nanoparticles are widely valued for their high electrical conductivity and reactivity. Common application areas include:
-
Conductive coatings, pastes, and inks
-
Electronic components and microelectronic devices
-
Catalysts (e.g., methanol synthesis)
-
Lubricant additives
-
Wear-resistant coatings
-
Sintering additives
