Ars Technica posted an interesting article about polymers who recover on their own. Immediately they were thinking to the iPhone-screen. With this kind of polymer, scratches would be a thing of the past. The human skin is able to recover itself in case of a wound, so why not other materials? The material, made by researchers of the university of Southern Mississippi, has similar properties. It works on influence of the solar light. The latest print of Science mentions it: the new polymer based on polyurethane – an elastic material which is already pretty scratch resistant.
The two extra components (OXE and CHI) create self-healing ability. OXE makes some kind of cut with 2 reactive borders and CHI makes it possible for the borders to connect again under the influence of solar light. The researchers scratched the CHI-OXE foil and it seemed to recover after half an hour under a 120 Watt UV-light.
Although these kind of screens is probably yet far away for iPhones, it could be used in screenprotectors, which are also scratched after a certain amount of time.
