Cerablak™ on glass

Very high quality transparent Cerablak™ films can be deposited on glass substrates with excellent adhesion.  Surface diffusion of sodium in glasses is of significant concern for many applications whereby the quality of overlayers is affected (for example, flat panel displays).  No suitable solution-based low-cost diffusion barrier layer has been developed to alleviate this concern.  Cerablak™ is an excellent choice to combat this long-standing problem and can be used over a wide range of processing temperatures.  It also seals off defects and flaws present on the surface, thus improving the mechanical strength of the glass article.  More importantly, Cerablak™ serves as an excellent host layer to strongly bond with organic overlayers.  For example, suitable organic layers can be deposited to induce hydrophobicity that can be useful for rendering a self-cleaning or easy-to-clean surfaces.  Designing glass surface chemistry with Cerablak™ film offers numerous opportunities in the energy, optics, and consumer electronics industries.

High contact angle with water is induced on a Cerablak™-coated slide by functionalizing the surface with suitable organic layers.  Such organic overlayers are thermally stable and mechanically robust.  Cerablak™ surface chemistry is highly suitable for attaining strong bonds with organics to render a hydrophobic or hydrophilic surface.
