The United States developed a permanent waterproof material or for ships

 

Julie Crockett, a professor of mechanical engineering at the University of Utah in Utah, and her colleague Dan Maynese, have developed a new technology that will permanently protect against water and bounce water from super-waterproof materials. As long as the surface of any object with a little structure, can achieve the purpose of water, the researchers said the technology in the future may be applied to ships or aircraft.
Any object, whether it is small tools or shoes, can be used to put them on a "raincoat" method of waterproof, but the raincoat always want to take off, these items will always be the risk of being wet.
Professor Zhu Li said that to produce super-waterproof material, not just to do a waterproof cover or waterproof wax, you must add a new waterproof structure. In nature, lotus leaves do very well, so Professor Zhu Li's laboratory constantly imitate lotus leaf waterproof structure. Super waterproof surface in the form of a variety of, in her laboratory, the use of bone cavity structure, can also be made of base structure, so it sat on it, like a ball.
When water falls on Professor Jolie's super-waterproof surface, it spreads out like ordinary water droplets. However, unlike ordinary water droplets, this water-repellent surface allows the dispersed water droplets to come together again until they come off the surface. She explains that the gravitational force between water molecules is greater than the gravitational force between the water molecules and the material, so they return to their original appearance before they pass through the material.
"The traditional waterproofing materials used to protect the surface of the form of paint, and we have to do is super waterproof surface, so we can not just focus on the surface of the water droplets, we are concerned about the surface of the water.
This waterproof material is widely used:
• wrapped outside the solar panels to prevent its dirty, it has a self-purification function;
• Prevent water droplets from splashing in bathrooms, toilets and water pipes.
• In the biomedical field, such as the infusion of the patient's infusion or the internal surface of some of the pipelines;
• Applies to ship hulls or torpedoes and submarines outside;
• Apply on aircraft wings to avoid freezing in cold or humid conditions.
In the long term, this material can also be used as a cleaning agent or to make energy more efficient. "Nearly every power station in the United States generates steam by burning coal or natural gas to power a turbine that rotates to produce electricity. If the power plant's condensers can be made from the ideal super water-repellent surface, then the speed will increase significantly, Reduce the cost of time to optimize the role of energy Once the liquid hit the condenser, it will be bounced away, then you can use very, very fast and efficient cooling a lot of gas.
