— The United States has developed permanent waterproof materials or used in ship aircraft —
— Details description —
Recently, a new technology developed by Julie Crockett, a professor of mechanical engineering at Brigham Young University in Utah, and her colleague Dan Maynes, is a super-waterproof material that is permanently waterproof and can bounce water. Waterproofing can be achieved by adding a small structure to the surface of any object. Researchers say the technology could be applied to ships or aircraft in the future.
    Any object, whether it's a gadget or a shoe, can be waterproofed by putting them on a layer of "raincoat", but the raincoat always has to be taken off, and these items are always at risk of being wet.
    When the water drops on Professor Julie's super waterproof surface, it spreads out like a normal water drop. But unlike ordinary water droplets, this waterproof surface allows the scattered water droplets to reunite together until they bounce off the surface. She explained that the gravitational pull between water molecules is greater than the gravitational pull between the water molecules and the material, so they regain their original appearance before they pass through the material.
    “Traditional waterproof materials protect the surface in the form of paints, and we have to do super waterproof surfaces, so we can't just focus on the water droplets on the surface. We are concerned about the surface water flow.”

This waterproof material is widely used:
    • Wrapped outside the solar panel to prevent it from becoming dirty, making it self-cleaning;
    • Prevent splashing of water droplets in bathrooms, toilets, water pipes, etc.
    • In the biomedical field, such as syringes for patient infusions or leaks inside some pipelines;
    • applied to the exterior of a ship's hull or torpedo and submarine;
    • Apply on aircraft wings to avoid freezing in cold or humid environments.
