Anti-icing coating, and preparation method therefor and use thereof

Abstract

A method for preparing an anti-icing coating includes: adding a mixture of an expandable microsphere and a photothermal nanomaterial to a high-temperature curable resin diluted with a diluent solvent, and uniformly dispersing a solution formed thereby to obtain a colloidal solution; transferring the colloidal solution to a surface of a substrate, heating the substrate with the colloidal solution attached thereto to volatilize the diluent solvent, and continuing heating the substrate to expand the expandable microsphere in the colloidal solution and to cure the high-temperature curable resin at or above an initial expansion temperature of the expandable microsphere; and heating the substrate to a maximum expansion temperature of the expandable microsphere to shrink the expanded microsphere, and cooling to obtain a three-dimensional porous coating; and performing a surface treatment on the three-dimensional porous coating, and injecting an oily liquid to obtain the anti-icing coating.
