While the iPhone finally adopted the water resistant feature, Samsung plans to take it a notch higher. Amid the Samsung Galaxy Note 7 fiasco, reports have started surfacing about the company signing a deal with US Department of Energy’s Oak Ridge National Lab (ORNL) for licence of a hydrophobic glass coating.
The USP of the glass coating is they don’t just offer water resistance, but ensure that water bounces back, leaving your device unharmed. Any fluid that hits the screen would bounce off, and you can even use the device in rain, just as you would otherwise.
To be superhydrophobic, a surface must achieve a water droplet contact angle that exceeds 150 degrees. The coating on this glass will come with droplet contact angle between 155 and 165 degrees, so the water simply bounces off. But it isn’t just about repelling water. The screen also works at reducing reflection and offers resistance from fingerprint marks. It is quite possible that Samsung may deploy the technology on its upcoming devices, in the bid to bring in a unique ability as water resistance is slowly being adopted by several companies. A Digital Spy report hints at it being too late to add the technology to Galaxy Note 8, but could see it Galaxy S9.
“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. Aytug led the technology’s development in collaboration with ORNL co-inventors Parans Paranthaman, Daniela Bogorin, David Christen, Brian D’Urso and John Simpson and was recognised with an R&D 100 Award in 2015.
