According to foreign media reports, in order to make ships and submarines more flexible, the US Naval Research Office has funded a 'liquid repellency' coating study. It will not only have the ability to waterproof but also block oil, alcohol and even peanut butter. Other materials. Recently, Anish Tuteja, an associate professor of materials science and engineering from the University of Michigan, developed a durable transparent chemical coating that reduces hull friction and makes the ship more energy efficient and concealed.
When the hull is cut through the water, it seems to be effortless on the surface, but in fact some water will remain on the hull, which causes the hull to generate friction with the water surface. Now, this new type of coating is very good. Solve this problem.
Ki-Han Kim, an ONR naval warfare and weapons department project officer, said that the fuel consumption of a ship (up to 80% at low speeds and 40%-50% at high speeds) is largely programmed to maintain speed and overcome frictional resistance. This means that the new lyophobic coating can significantly reduce the fuel consumption of the ship.
In addition, this smooth, frictionless hull means that it can sail quietly on the surface of the water, even if it is detected at high speeds.
Right now, the composition of this lyophobic coating developed by Tuteja has not been announced. It is only known that its team uses computer mathematics libraries of known chemicals and they are complexly modeled to predict each other. The interaction and properties. The final product is a transparent rubbery material that can be sprayed onto many surfaces and tightly bonded to it without the effects of scratches, dents and the like.
According to Tuteja, this coating can be used as a protector for sensors, radar units and antennas used in inclement weather, in addition to being used in ships. Currently, this material is still being tested but the research team believes it will Can be applied to small-scale military and civilian applications in the next two years.
