Engineers from Duke University have discovered a way to help vessels shake off the unwanted accumulation of bacteria and other marine growth, known as ship scum, using stretching, pressure or electricity.
Engineers have designed a novel material that can be applied like paint to the hull of a ship and will be able to prevent bacteria from accumulating by dislodging it from the ship’s surface. Ship scum increases drag and reduces the energy efficiency of the vessel, in addition to preventing undersea sensors from working properly.
