Abstract
Superhydrophobic coatings with a thickness of 0.7–1.3 μm based on montanic acid (MA) are formed by dynamic spin-coating on substrates made of single-crystal silicon and steel of the 12Kh17 brand. The contact angle (CA) for water is 154.2° in the case of MA coatings on silicon and 155.8° in the case of those on steel. The values of the CA of these coatings for hexadecane are less than 5.0°, which makes it possible to use MA for hydrophobization of the surface of metal filters for the purpose of separating emulsions of the water-in-oil type.
