Copper nanoparticles (60-100 nm, 99.9% metals basis) are a specialty chemical valued for their high surface area and enhanced reactivity compared to bulk copper. They are widely used in electronics for conductive inks, pastes, and flexible circuits due to excellent electrical conductivity. In catalysis, copper nanoparticles act as efficient catalysts for organic reactions, hydrogenation, and CO2 reduction processes. Their superior thermal conductivity makes them suitable for thermal management in heat exchangers and advanced materials. In agriculture, copper nanoparticles serve as nano-fungicides and in targeted delivery systems for fertilizers, providing algae control in water treatment. Antimicrobial properties enable applications in healthcare, such as antibacterial coatings, medical devices, and hospital touch surfaces to inhibit bacterial growth. Additionally, they are incorporated into alloys, lubricants for friction reduction, and energy storage solutions like batteries and supercapacitors.
