  • Publication number: 20220213367
    Abstract: An intelligent anti-icing material and a preparation method and use thereof are disclosed. The intelligent anti-icing material includes a hydrophobic resin and a nickel-titanium alloy wire embedded in the hydrophobic resin. When the surrounding temperature decreases, the hydrophobic resin in the intelligent anti-icing material shrinks, and the nickel-titanium alloy wire featured by thermoelastic martensitic transformation undergoes phase transformation and expands, which changes the direction of the expansion force inside the ice layer, and thus tiny cracks occur at the interface between the ice layer and the surface of the material, thereby reducing the adhesion of the ice layer to the surface of the material, accelerating the spontaneous shedding of the ice layer, without heating, and achieving an excellent anti-icing effect.
