Most waterproof material

In 2013, a team of materials scientists from the Brookhaven National Laboratory in New York, USA, created the world’s most waterproof material by engineering a surface with nano-scale structures. Conventional waterproof fabrics still become “wet” in some form or other, but in this case thin, pointed cone structures force water to ball up and roll away, even when it is sprayed at extremely high velocities. The super-hydrophobic surface is unlike other water-resistant materials because it can stand up to extremes of temperature, pressure and humidity. The coated surfaces are not only waterproof, but also stay cleaner (since the water droplets carry dirt with them). Ultimate uses could include coatings for boat hulls, car parts and medical devices, car and plane windshields, and even steam-turbine power generators. The surface is so waterproof that conventional standards for quantifying waterproof materials cannot be applied to measure this new nanostructure material. To all intents and purposes, this is a completely waterproof material.
