MULTIFUNCTIONAL ADDITIVE TO COATINGS Russian patent published in 2020 - IPC C09D5/14 B82B3/00 B82Y40/00 

FIELD: chemistry.

SUBSTANCE: invention relates to compositions of multifunctional nanostructured additives to coatings, such as lacquer, paint, enamel, in order to prevent corrosion processes and biofouling of underwater parts of ships and offshore structures. Multifunctional coating additive contains the following in wt. %: corrosion inhibitor and organic biocide in molar ratio 0.5–2.0/5.0–10.0, conducting polymer 10.0–40.0, copper or zinc nanoparticles 2.0–10.0, aluminosilicate nanotubes are the rest, up to 100. Aluminosilicate nanotubes are intercalated by a corrosion inhibitor and an organic biocide and coated with a layer of a conducting polymer with nanoparticles of copper or zinc on the surface of the polymer layer.

EFFECT: technical result consists in provision of intercalation of aluminosilicate nanotubes with corrosion inhibitor and organic biocide and coating of said nanotubes with layer of conducting polymer with nanoparticles of copper or zinc on surface.
