(Source: P2i) UK-based P2i has developed a waterproof nano-coating that protects smartphones such as the alcatel One Touch, and motorola's raZr and XOOm. We think the company should develop the technology for consumers who want to apply it to the devices they already own. 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. According to P2i, Aridion does not affect conductivity or the functioning of components, and is so thin that it doesn't change the product's look and feel. Since the coating becomes an inseparable part of the material it bonds to, it is as durable as the materials it protects. No solvents are used in the application process, which consumes only tiny amounts of the protective monomer. The first commercial application for electronics was coating hearing aids. The company says the coating can be applied to a wide variety of materials, including fabrics, polymers, metals, ceramics, glass, leather, and paper, as well as objects made of multiple materials, such as smartphones and tablets. Another version of the coating, ion-mask, is used on shoes and clothing. The technology was originally developed during UK defense research projects. In that research, the aim was to protect soldiers' clothing from chemical weapons. The videos on the company's website showing liquid rolling off are pretty impressive. I think P2i should try to figure out how to apply this coating to existing electronic devices, presumably while they're still new. Places like Kinkos could buy one of the chambers and offer a retrofitting service for electronics that haven't already been protected. — Ann R.
