Case 14861/14941

Process for manufacturing glass with micro/nanostrutured surface texture


Nanostructured surface, glass manufacturing, fabrication method, self-cleaning, anti-fogging, anti-reflection


Self-cleaning, anti-glare displays and increased solar panel efficiency


Reflection, fogging and dirt-collection on the surface of glass.


This invention is a nanostructured surface that has a high aspect ratio (large height over small features sizes) to provide better optical and wetting properties of glass. The invention includes a manufacturing process for the surface.

  • Anti-glare, anti-fog, self-clean
  • Compatible and adaptable to conventional 2-D lithography techniques
  • Both aspect ratio and profile of nanocone structure can be controlled
