Drop Your Phone in the Sink – We Dare You

On some Design News message boards, we've discussed how great it would be if consumer electronics like smartphones and tablets were rougher and tougher. What if you could actually drop one into the sink by accident, or into your plate of spaghetti sauce, and no harm would be done?A nanoscale coating that's now being applied to some smartphones will let you do that (though we don't recommend it). Aridion, developed by P2i, is used by Motorola on its RAZR and XOOM phones, and by Alcatel on its One Touch phones. About 30nm thick, or 1,000 times as thin as a human hair, the hydrophobic polymer coating is applied to completed products at the end of the manufacturing process. It coats exterior surfaces, ports, and even interior components, protecting them against liquids and stains, according to a P2i video, which you can watch below.The coating, based on perfluorinated carbon compounds, is applied via a plasma-enhanced vapor deposition process that lays it down on all of the device's internal and external surfaces. The process takes place under low pressure in a vacuum chamber at room temperature. The vaporized polymer bonds at the molecular level to materials, reducing corrosion and water damage. The polymer layer reduces surface energy, so instead of being attracted and spreading out on the device's surface, water and other liquids bead up and roll off.
