METHOD OF OBTAINING POLYMER COATING ON ALUMINUM SURFACE Russian patent published in 2019 - IPC B05D7/14 B05D3/10 C23C22/05 C23C22/78 C23C22/83 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for producing polymer coatings, having hydrophobic properties that can be used as anti-icing coatings, on the surface of a metal, for example, aluminum, protective coatings for electronics, self-cleaning surfaces, as well as coatings to protect against biofouling. Method of obtaining a polymer coating on the surface of aluminum is described, including degreasing of the surface of aluminum with acetone, treatment with 1M sodium hydroxide solution, water, the subsequent drying and modification of the surface, in which the degreasing of the aluminum surface is carried out before the treatment with sodium hydroxide solution; after the treatment with sodium hydroxide solution, the surface is etched with 2M–5M solution of hydrochloric acid and conditioned at 140 °C, and the modification of the aluminum surface is carried out with 3 wt. % solution of the copolymer of glycidyl methacrylate and 1,1,1,3,3,3-hexafluoroisopropyl methacrylate, taken in a molar ratio of 0.6:1, respectively, previously obtained at 70 °C in the presence of azobisisobutyronitrile in methyl ethyl ketone medium, followed by conditioning of modified aluminum at 140 °C.

EFFECT: technical result is to obtain a polymer coating with superhydrophobic properties on the aluminum surface.
