Abstract—Coatings are made using SKTN-f methylphenylsiloxane rubber with different contents of PMS-200 polymethylsiloxane oil and BS-100 white carbon nanoparticles. The authors studied the abrasion resistance and hydrophobic properties (wetting angle, roll-off angle) of coatings and ice adhesion to their surfaces. It is shown that the introduction of polymethylsiloxane oil into the polymer matrix decreases abrasion resistance and hydrophobic properties of the coatings, while at the same time reducing surface ice adhesion. It was established that the introduction of BS-100 nanoparticles can increase the physicomechanical characteristics of coatings while maintaining the level of functional properties. The obtained results for the dependence of functional properties on the chemical composition of the coatings are explained by their structural features; in particular, polymethylsiloxane oil is evenly distributed over the bulk of the polymer matrix, enveloping agglomerates of white carbon nanoparticles emerging on the surface, thereby forming a multimodal roughness, which in turn increases the hydrophobic properties of coatings.
