Nano CuO Copper Oxide Powder for Antimicrobial

Nano CuO Copper Oxide Powder for Antimicrobial

Specification of Copper Oxide(CuO) Nanopowder

Breif introduction of nano CuO powder:

Copper oxide nanoparticle is a kind of brownish black metal oxide powder, which has a wide application. In addition to the role of catalyst and sensor, an important role of nano copper oxide is antibacterial.

Introduction of the application of nano size copper oxide in antibacterial:

Antibacterial principle:

The antibacterial process of copper oxide can be simply described as follows: under the light excitation of energy greater than the forbidden band width, the hole - electron pairs generated will interact with O2 and H2O in the environment, and the free radicals generated such as reactive oxygen species will have chemical reactions with organic molecules in cells, so as to decompose cells and achieve the purpose of antibacterial.CuO is a p-type semiconductor with holes (CuO) +, which may interact with the environment and play an antibacterial role.The results show that CuO has good bacteriostatic activity against various cariogenic bacteria, pneumonia and pseudomonas aeruginosa.

Advantages, application fields of nano CuO materials for antibacterial:

Copper oxide nanopowder has high chemical stability and thermal stability: CuO nano powder is used for antibacterial and has long-term bactericidal and antibacterial effects, acid and alkali resistance, washing resistance, not easy to produce bacterial resistance, slow release, long-lasting bactericidal effect. Nano CuO materials as antimicrobial can be widely used in fiber, plastic, paint, fabric, agriculture etc.
