Scientists from the Department of Energy’s Oak Ridge National Laboratory have developed optically clear superhydrophobic film technology. It improves the performance of glass displays on smartphones, tablets, and other electronic devices.
The coating repels water that carries away dust and dirt. Additionally, it reduces light reflection and resists fingerprints and smudges, resulting from approximately three years of superhydrophobic research on glass-based coatings.
It consists of a layer of the porous glass film. Thus, it enables those combined properties by making them suitable for commercial applications.
The superhydrophobic film achieves a water droplet contact angle exceeding 150 degrees. But, ORNL’s superhydrophobic film has a contact angle of between 155 and 165 degrees. Thus, water literally bounces off, taking away dust particles.
Super Hydrophobic (NeverWet) Waterproof Technology
Scientists developed this technology by depositing a thin film on a glass surface.
They then heat the coated glass to transform the surface into two material compositions. Thus, a specific etching process generates a porous three-dimensional network of high silica-content glass. It simulates microscopic coral and enables water-repellent and antireflective properties.
This superhydrophobic film has an essential potential to be used inside solar panels, lenses, detectors, windows, and many other products.
