Zinc Oxide (ZnO) nanoparticles

Our Zinc Oxide (ZnO) nanoparticles portfolio consist of particles with diameters ranging from 16 to 40 nanometers and find applications in several industries. Among our customers we find personal care products&cosmetics, electronics, coating and tiles industry.

We at Particular Materials synthesize nano ZnO and we produce and supply dispersions with excellent stability, monodispersity and fully disaggregated state.

Technical Information

ZnO nanoparticles with sizes below 20 nm display UV absorption behavior without light scattering and they are extensively employed as inorganic UVA and UVB filters. They are also being investigated to kill harmful microorganisms in packaging, with antibacterial and antifungal properties, and in UV-protective materials such as textiles.

ZnO nanostructures have been shown to be prominent photocatalyst candidates to be used in photodegradation owing to the facts that they are low-cost, non-toxic and more efficient in the absorption across a large fraction of the solar spectrum compared to TiO2.

ZnO is a semiconductor with a wide bandgap (3.37 eV) and therefore interacts with UV-light: as well as being an excellent inorganic UV filter it is used as UV photodetector, in field emission displays as well as electrical and optical devices and solar cells.

In order to be able to take advantage of the various properties of Zinc Oxide (ZnO) nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.

We at Particular Materials synthesize nano TiO2 and we produce and supply dispersions with excellent stability, monodispersity and fully disaggregated state.

The ZnO nanoparticles are available in two different sizes:

  • 16 ± 4 nm
  • 40 ± 20 nm

Typical concentration in water are, by weight (w/w%):

  • 1%
  • 5%
  • 10%
  • 20%

ZnO can also be provided as nanopowder.

Related Applications and Industries

One of the primary uses of ZnO nanoparticles is within coatings, to impart unique properties such as UVA and UVB filtration and antimicrobial and antifungal properties. Many coating use zinc oxide particles specifically as a coating agent.

Like other nanomaterials with antimicrobial properties, zinc oxide nanopowders are of value in the production of ceramics, especially those for use in sterile environments, public places, tiles, shopping malls, hospitals and restaurant.

In the cosmetics and personal care industry, many creams, ointments, moisturizers, and beauty products utilize zinc oxide for its antimicrobial and optical properties. ZnO acts as non whitening UVA and UVB filter in sun screens.

Zinc Oxide is used as an electron injecting layer for OLEDs, as an electron-transporting layer (ETL) material, as well as to improve surface and electronic properties of direct and inverted OPVs.

A peculiar characteristic of all nanoparticles is the high surface area to volume ratio, that allows a considerably higher binding capacity and excellent dispersibility of NPs in solutions.
