Transparent SH film on Borosilicate glass

Touch resistance

This is a durable transparent thin-film glass coating developed at Oak Ridge National Laboratory. This surface offers high optical transparency, mechanical durability, superhydrophobicity, anti-reflectance, uniformity, density, UV reduction, and other adjustable features; and it has been developed so that it can easily be adopted by industry. This particular video demonstrates the durability touch resistance. Ongoing work indicates anti-smudge/fingerprinting properties.

Al2O3 wear test

This is a durable transparent thin-film glass coating developed at Oak Ridge National Laboratory. This surface offers high optical transparency, mechanical durability, superhydrophobicity, anti-reflectance, uniformity, density, UV reduction, and other adjustable features; and it has been developed so that it can easily be adopted by industry. This particular video demonstrates the durability of the coating when highly abrasive Aluminum Oxide is sprayed at high speed. Tests so far indicate extreme durability that actually improves the desirable properties. This also shows the self cleaning properties of the coating.

Moses effect

This is a durable transparent thin-film glass coating developed at Oak Ridge National Laboratory. This surface offers high optical transparency, mechanical durability, superhydrophobicity, anti-reflectance, uniformity, density, UV reduction, and other adjustable features; and it has been developed so that it can easily be adopted by industry. This particular video demonstrates the "moses effect" of the coating. The coating has a thin layer of air that is pinned to the surface. When the are is immersed in water, the coating is not wetted, and this is demonstrated when the liquid is removed.

High speed camera SH transparent film

This is a durable transparent thin-film glass coating developed at Oak Ridge National Laboratory. This surface offers high optical transparency, mechanical durability, superhydrophobicity, anti-reflectance, uniformity, density, UV reduction, and other adjustable features; and it has been developed so that it can easily be adopted by industry. This particular video demonstrates the superhydrophobicity of the coating applied to a cracked surface and filmed with a high speed camera. Even thought the substrate is cracked the coating works the same across it.

Metal oxide SH coatings

This is a durable thin-film metal-oxide coating developed at Oak Ridge National Laboratory. This surface offers mechanical durability, superhydrophobicity, and other adjustable features; and it has been developed so that it can easily be adopted by industry. This particular video demonstrates the "moses effect" of the coating. The coating has a thin layer of air that is pinned to the surface. When the are is immersed in water, the coating is not wetted, and this is demonstrated when the liquid is removed.

Metal oxide SH coatings

This is a durable thin-film metal-oxide coating developed at Oak Ridge National Laboratory. This surface offers mechanical durability, superhydrophobicity, and other adjustable features; and it has been developed so that it can easily be adopted by industry. This particular video demonstrates the superhydrophobicity, or water repelling abilty of the coating. The coating has a thin layer of air that is pinned to the surface. When the are is immersed in water, the coating is not wetted, and this is demonstrated when the liquid is removed. The droplet contact angle is greater than 170 and the roll off angle is less than 10
