Intelligent anti-icing material, and preparation method and application thereof

TLDR: In this paper, an intelligent anti-icing material consisting of hydrophobic resin and nickel-titanium alloy wires embedded in the hydrophilic resins has been presented.

Abstract: The invention belongs to the technical field of composite materials, and particularly relates to an intelligent anti-icing material, and a preparation method and application thereof. The invention provides an intelligent anti-icing material. The intelligent anti-icing material comprises hydrophobic resin and nickel-titanium alloy wires embedded in the hydrophobic resin. When the ambient temperature reduces, the hydrophobic resin in the intelligent anti-icing material disclosed by the invention can shrink; the nickel-titanium alloy wires with a thermoelastic martensite phase transformation characteristic is subjected to phase transformation and is expanded; and the direction of expansion force in an ice layer is changed, so that tiny cracks are generated on the interface between the ice layer and the surface of the material, the adhesive force of the ice layer on the surface of the material is reduced, automatic falling of the ice layer is accelerated, and an excellent anti-icing usingeffect is achieved without need of heating. Experimental effects show that the intelligent anti-icing material disclosed by the invention has a good anti-icing effect; under the condition of-20 DEG C,compared with a non-intelligent anti-icing composite material, the intelligent anti-icing material provided by the invention has the advantage that the adhesion force of an ice layer on the surface is reduced by 18.2%-24.2%.
