The Development of Coatings That Give Superhydrophobic Properties to the Surface of Silicone Rubber

Hydrophobizing agents on the basis of functional silanes with fluorohydrocarbon substituents have been synthesized. Using these agents and Aerosil nanoparticles, textured coatings were developed that give superhydrophobic properties to the surface of electrotechnical rubbers. Specific features of interaction between the hydrophobic surfaces and water were studied based on analysis of contact angles. For all the hydrophobic materials and coatings studied, even during short-term contact with water, the change in the state of the material surface is shown to be taken into account, with the proposed superhydrophobic coatings demonstrating the most long-term water resistance.
