Functional Coatings & Nanocomposites
Our offerings in Fuctional Coatings & Nanocomposites fits within our NanoCeramics product group.
Conformal coatings on high aspect ratio surfaces are available for all our AAO membrane and nanotemplate products as well as on customer provided samples.
Schematic illustration of ALD
These coatings are deposited using Atomic Layer Deposition (ALD). ALD is a gas-based, surface-driven deposition technique that is uniquely suited to coating ultrahigh aspect ratio structures, such as nanopores in AAO, enabling precise control of the coatings thickness and composition.
ALD coatings are available with thicknesses ranging from 1 to 10 nm, conformally covering AAO pores with aspect ratio (length to diameter) as high as 5,000. Nanolaminates, where the deposition is cycled between two or more chemistries, resulting in alternating layers of different compositions, are also available
Currently available ALD coatings:
- Standard options: Al2O3, ZnO, TiO2, conductive Al-doped ZnO
- Custom Options: GaN, Ga2O3, In2O3, nanolaminates
Functionality of coatings:
- Sealing materials: Al2O3, ZnO
