Abstract

The invention discloses a preparation method of carbon nanotubes assembled capsaicin repellent biological antifouling marine paint. The invention first activates carbon nanotubes with nitric acid and stearic acid, and uses trifluoroethyl methacrylate as a monomer, Polymerization under the action of an initiator to obtain a polyester emulsion doped with carbon nanotubes, and then dispersing the acetone solution of capsaicin into the polyester emulsion to realize the intercalation and assembly of capsaicin between carbon nanotubes, sustained release and The affinity with the ship bottom steel plate improves the fastness and slow release service life of the ship bottom coating. In the invention, the modified capsaicin is assembled with carbon nanotubes as an effective component, and the biological repelling and anti-corrosion effects of using capsaicin in a long life can be achieved.

Description

technical field [0001] The invention belongs to the field of marine anticorrosion, and in particular relates to a preparation method and an application of a capsaicin repellent biological antifouling marine paint assembled with carbon nanotubes (multi-wall). Background technique [0002] As we all know, the attachment of marine organisms to the surface of a ship will not only significantly increase the mass of the hull, increase navigation resistance, reduce the speed of the ship, thereby increasing fuel consumption, but also accelerate the corrosion of the ship's bottom and shorten the service life. In order to reduce the harm of marine organisms and prevent marine organisms from fouling ships, people have studied a variety of antifouling technologies. In the past few decades, compounds such as mercury and arsenic were used to formulate antifouling coatings in the early stage, but they were eliminated due to the toxicity of these substances and polluted the marine environme...
