Why Zirconia?

We create precisely controlled zirconia nanocrystals and disperse them into polymers to produce crystal clear dispersions and deliver revolutionary optical properties.

Zirconia possesses a unique combination of physical and chemical properties, including high refractive index, high optical transparency from UV to infrared, high dielectric constant, high hardness, and high chemical inertness, allowing for uses in a broad array of applications.

Benefits:

Incorporating Pixelligent’s products into existing materials creates unparalleled optical properties, including high refractive index, near-perfect optical clarity, and polymer-like processability. The optoelectronics industry has been searching for a high-RI material with this combination of benefits, which is required to enable the next generation of solid state lighting, display, and optical applications.

Process

  1. Nanocrystal synthesis

    Pixelligent’s scalable synthesis reaction generates sub-10 nanometer zirconia nanocrystals. We are able to precisely control the size and shape of our nanocrystals, and our liquid synthesis process prevents agglomeration and avoids solids handling at any point.

  2. Surface modification

    Our capping technology allows us to control the surface chemistry of the nanocrystal by chemically bonding materials such as polymers, silicones, and functional groups to the nanocrystal surface. These customized surfaces ensure our nanoparticles are evenly dispersed and stable, and allow them to be incorporated into many commonly used polymers, acrylics and epoxies. Multiple capping agents can be added to create custom surface chemistries.

  3. Dispersion

    Pixelligent can disperse nanocrystals into a variety of solvents and polymer families such as: acrylics, silicones, siloxanes, epoxies and more. Our nano-enabled materials can also be formulated into complex polymer systems for multiple applications. Incorporating Pixelligent’s nanocrystals into these polymers can significantly increase the refractive index without altering the viscosity, even at high loadings.

Manufacturing

We have demonstrated that our liquid synthesis technology produces consistent, high-quality dispersions at a 40-ton annual scale. We manufacture and ship our products as liquid dispersions, which has allowed us to gain TSCA compliance.
