Al2O3 and CuO nano particulate-based paints for marine applications

Abstract The present study focuses on the Preparation of Aluminum Oxide, and Copper oxide antifouling coatings to prevent or reduce corrosion and fouling in ships and marine vehicles. Al 2 O 3 and CuO nanoparticles were prepared using the ball milling process. The nano paints were prepared using these nanoparticles as pigment and linseed alkyd resin as a binder. Mild-steel specimens coated with nano paint were immersed in seawater for 120 days and the properties were studied using Scanning electron microscopy, SEM—EDAX, X-ray Diffraction, and Fourier transform-infra red spectroscopy. It found an improvement in anti-fouling exhibited by Al 2 O 3 mild steel plates and also an improvement using CuO when compared to bare paint. Contact angle measurement showed a marked increase for base paint which indicates its hydrophobic nature.
