Applications
Where Cu nanoparticles change the game
Copper nanotechnology is deployed today across antimicrobial, conductive, polymer and anticorrosive industries — wherever the surface-to-volume ratio of the metal matters.
Bactericidal agents
Active antimicrobial agents for hospital surfaces, textiles and water treatment.
Conductive inks
High-conductivity inks for printed electronics, RFID, flexible circuits and PV.
Polymer additives
Masterbatches, resins, paints, coatings and textile fibers gain durable Cu performance.
Anticorrosive coatings
Surface treatments that extend equipment lifespan in aggressive environments.
