Copper (Cu) Nanopowder Main Feature
The nanoscale size of copper particles results in a significantly increased surface area-to-volume ratio. This high surface area is advantageous in catalysis, enhancing the chemical reactivity and efficiency of catalytic processes.While copper inherently has excellent electrical conductivity, the nanopowder form can provide even greater efficiency in electrical and electronic applications due to its high purity and reduced granular boundaries.Copper nanopowder can also exhibit enhanced thermal conductivity. This property is beneficial in applications requiring efficient heat dissipation, such as in thermal management systems for electronics.Copper nanoparticles possess strong antimicrobial properties against a wide range of microorganisms. This makes them suitable for incorporation into coatings, textiles, and medical devices to reduce the risk of bacterial and fungal infections.
