Zirconia (ZrO2) Nanocrystals and Composites

The Zirconia (ZrO2) nanocrystals have significantly contributed to the commercial scalability of optical materials. The development of organic–inorganic composites from ZrO2 nanoparticles (NPs) is one of the latest innovations in this area.

The organic polymer materials provide low molecular weight, manufacturing processability, flexibility. Inorganic materials like ZrO2 offer hardness, strength, transparency and a high refractive index.

The combination is crucial for manufacturing clear dispersions and films. Merck provides ZrO2 NPs that possess a wide range of functionalizations and compositions for several optical materials.
