Engineers at The Australian National University (ANU) have developed a new spray-on material with a remarkable ability to repel water. The new protective coating could eventually be used to waterproof mobile phones, prevent ice from forming on aeroplanes or protect boat hulls from corroding. "The surface is a layer of nanoparticles, which water slides off as if it's on a hot barbecue," said PhD student William Wong, from the Nanotechnology Research Laboratory at the ANU Research School of Engineering.
