Eco-Friendly Capsaicin-Containing Water-Based Antifouling Coatings for Marine Aquaculture

Natural antifoulants have received significant interest in the search for non- or less-toxic antifouling coating systems marine structures. Capsaicin, a natural compound that can be found chili peppers, is known as an environmentally friendly agent with excellent performance and low environmental impact. However, controlling its release from matrix still issue to solved. With aim of developing eco-friendly system prolonged long-term activity, this study, we incorporated capsaicin combination dichlofluanid into water-based acrylic formulations. The activity resulting coatings was studied by examining survival behavior Gram-negative bacterium Aeromonas Salmonoid ATCC 33658, rate paint also assessed. 0.75 wt.% same showed antibacterial up 99.9% cfu reduction value R 2.5–3 times higher than those obtained single biocides at 1.5 wt.%. association between two organic created synergistic effect on performance, further activity.
