Default Nokia building a superhydrophobic coating for devices

Hydrophobic surfaces are by no means new technology; for instance, Teflon frequently covers cookware, and nature also has examples such as with the lotus leaf. What sets certain coatings apart is the contact angle between the droplet and the surface that's been coated. That angle is expressed as the angle between the water on the edge and the surface under it (look at this illustration for a better idea). Several new hydrophobic coatings for devices were demonstrated before and during CES, but I've not seen one quite as impressive as what Nokia's bringing to the table.

Demonstrated in the video is the difference between a hydrophobic and superhydrophobic coating. Superhydrophbic coatings utilize nanostructures to increase the contact angle to nearly 180° and trap a layer of air between the surface and the water, helping the water to slide off the surface easily. The coating can already be applied to the inside of a device, but the outside poses its own unique challenges, the greatest of which is making the coating robust enough to adhere to the surface through rubbing, scratching, and other common forms of contact. Internal coating is important, as it is the last line of defense against water damaging the components that make the phone run, but the external coating is important as well, with the added benefit of help keeping your screen clean. The technology isn't complete, but it's close, and we can expect to see this technology applied to Nokia phones in the future, keeping with their standard for excellence.
