Description

technical field [0001] The invention relates to a three-dimensional network structure graphene-based material with anti-icing and deicing functions and a preparation method thereof. Background technique [0002] Superhydrophobic materials are considered to be the anti- / de-icing materials with the most development potential and application prospects in the aviation field. When the aircraft flies under the weather conditions where the ambient temperature is below the freezing point or near the freezing point, the supercooled water droplets in the atmosphere hit the surface of the aircraft, and it is easy to freeze on the surface of the rotor, wing, empennage and other components. Icing not only increases the weight, but also causes changes in the surface roughness and shape of the aircraft, destroys aerodynamic performance, and in severe cases will cause air parking or crashes. [0003] Superhydrophobic materials prevent the condensation of water droplets by changing the phys...
