The team recently published a paper detailing their findings: "Creating Glasswing-Butterfly Inspired Durable Antifogging Omniphobic Supertransmissive, Superclear Nanostructured Glass Through Bayesian Learning and Optimization" in Materials Horizons (doi:10.1039/C9MH00589G). They recently presented this work at the ICML conference in the "Climate Change: How Can AI Help?" workshop.

The nanostructured glass has random nanostructures, like the glasswing butterfly wing, that are smaller than the wavelengths of visible light. This allows the glass to have a very high transparency of 99.5% when the random nanostructures are on both sides of the glass. This high transparency can reduce the brightness and power demands on displays that could, for example, extend battery life. The glass is antireflective across higher angles, improving viewing angles. The glass also has low haze, less than 0.1%, which results in very clear images and text.

Glass - Variety - Liquids - Orange - Juice

"The glass is superomniphobic, meaning it repels a wide variety of liquids such as orange juice, coffee, water, blood, and milk," explains Sajad Haghanifar, lead author of the paper and doctoral candidate in industrial engineering at Pitt. "The glass is also anti-fogging, as water condensation tends to easily roll off the surface, and the view through the glass remains unobstructed. Finally, the nanostructured glass is durable from abrasion due to its self-healing properties -- abrading the surface with a rough sponge damages the coating, but heating it restores it to its original function."

Natural surfaces like lotus leaves, moth eyes and butterfly wings display omniphobic properties that make them self-cleaning, bacterial-resistant and water-repellant -- adaptations for survival that evolved over millions of years. Researchers have long sought inspiration from nature to replicate these properties in...
