Abstract: To improve the anti-corrosion and waterproof performance of marine vessel surfaces, many acrylic resin coating materials have been proposed, but many of them still have the problem of low anti-corrosion performance. To address this problem, nanocomposites based on modified multi-walled carbon nanotubes are proposed in the study with a view to improving the anticorrosive properties of acrylic resin coating materials. The study first examined the structure of the nanocomposite using relevant instruments. The results showed that the nanocomposite was able to mix SiO2, multi-walled carbon nanotubes, and 1H,1H,2H,2H-perfluorodecyltrimethoxysilane efficiently with good waterproofing and anticorrosion properties. Subsequently, the nanocomposites were applied to acrylic resin coating materials for experiments. The outcomes revealed that the coating material had a contact angle of 131.8° and an average impact strength of 58.3 kg·cm. The impedance value was much higher than 109 Ω·cm2 after immersion in 3.5 wt% NaCl solution for 8 days, and the impedance value was stable. The above results indicate that the nanocomposites based on modified multi-walled carbon nanotubes proposed in the study can improve the anticorrosive properties of acrylic resin coating materials. This study provides a scientific basis for improving the anticorrosion performance of marine vessel surfaces.
