New graphene nanoribbon epoxy coating enables melting of ice on aircraft wings
 |
For the winter flight, the important natural enemy that affects flight safety is the icing of aircraft wings. When the aircraft is parked at the airport, the crew can use special de-icing fluid to de-ice the wing, but when the aircraft encounters icing at high altitudes, there is currently no ideal solution. Recently, scientists at Rice University in Texas, USA, have created a new graphene nanoribbon epoxy coating that, after being applied with voltage, is able to melt the ice by the generated electric heat.
Under the leadership of Professor James Tour, the researchers combined the epoxy coating with the graphene nanoribbons. Graphene nanoribbons are two-dimensional crystals composed of a single layer of carbon atoms. The flat graphene nanoribbons prepared by the researchers have excellent electrical conductivity.
In laboratory tests, the researchers set the temperature to minus 20°C and coated the epoxy coating on the edge of the helicopter rotor blades. When the coating was applied with a small voltage, the coating surface was created. Electric heating up to 93°C can melt more than 1cm thick ice.
In addition, this coating can also provide the aircraft with an electromagnetic shielding layer to help protect the aircraft from lightning strikes.
