Abstract
The work is devoted to the study of the possibility of using stearic acid and 1-dodecanethiol as hydrophobizators to obtain a superhydrophobic coating. Stearic acid was otained from an alcoholic solution, 1-dodicanthiol both from an alcoholic solution and from vapors. To test hydrophobizators, a dendritic coating was used, obtained from a dilute copper plating sulfate electrolyte at the limiting diffusion current, followed by reinforcement the resulting structures with a thin layer of metal deposited at a low current. The thicknesses of the resulting layers of stearic acid and dodecanethiol-1 were estimated, the effect of hydrophobizators on the coating morphology at the micro- and submicro - levels was studied, the wetting angles on the resulting coatings and their stability in a corrosive-aggressive environment were measured.
