WETTING OF HYDROPHOBIC AND HYDROPHILIC COATINGS

A technology of formation of a superhydrophobic coating has been presented which is based on a combination of mechanical punching and vapor deposition of carbon nanoparticles. Contact angles for hydrophobic coatings have been measured. Transport properties of hydrophilic porous coatings from aluminum-oxide nanoparticles have been investigated. A method to increase the height of rise of a liquid by forming microtrenches in the coating has been proposed. The height of capillary rise for coatings with microtrenches has been measured.
