Abstract
The anti-icing properties of coatings based on the developed composition areconsidered. It was shown, that after wetting during 72 hours, the coatings based on the proposed composition retained a superhydrophobic effect. The wetting angle on the mortar substrate was more than 150 degrees. Adhesion of coatings to the substrate after wetting amounted to 1 point. Information is given about the results of evaluation of the adhesion of ice to a superhydrophobic metal surface. It is shown, that the force of detachment of a drop of water on a superhydrophobic metal surface is 3 times less. It ensures easier rolling of a drop of water from the surface and its anti-icing properties. It is established, that the adhesion of ice to the superhydrophobic surface is less compared to the hydrophilic one. It is shown, that there is no difference in the rate of ice evaporation on a hydrophilic and superhydrophobic surface. The research indicate that the proposed composition forms a coating characterized by anti-icing properties that remain in service.
