Effect of Metallic Nanoparticle-Dispersed Silane- Based Polymer Coatings on Anti-Biofilm Formation

Akiko Ogawa and Katsuhiko Sano

Abstract

Regulating biofouling is important for the maintenance of marine vessels, bridges, and other constructions. Marine organisms must also be protected. Here we propose a silane-based polymer coating that has features of both polysiloxanes and silicates: nontoxicity, weatherability, and a self-cleaning effect as an anti-biofouling method. We focus on the antibacterial activity of some metals and metallic nanoparticles applied to the silane-based coating that can remove biofouling at the late stage of biofilm formation and may be effective at the early stage. Silver, nickel, or copper nanoparticles dispersed to a silane-based polymer coating exhibit antibiofouling behavior, whereas tungsten or molybdenum nanoparticles enhance biofouling.
