Oak Ridge National Laboratory announced this fall that Samsung Electronics has exclusively licensed a technology that can improve the performance of glass displays on smart phones, tablets, and other electronic devices.
ORNL has developed a transparent coating that repels water, carrying away dust and dirt; reduces light reflection; and resists fingerprints and smudges. The optically clear superhydrophobic film technology was the result of about three years of superhydrophobic research on glass-based coatings, ORNL said in a press release.
“The thin nanostructured layer of porous glass film enables these combined properties, making it suitable for commercial applications,” said ORNL’s Tolga Aytug, co-inventor of the technology.
To be superhydrophobic, a surface must achieve a water droplet contact angle exceeding 150 degrees. ORNL’s coating has a contact angle of between 155 and 165 degrees, so water literally bounces off, taking away dust particles, the press release said. [Read more…]
