Abstract

Since ancient times, people have fought against unwanted organisms growing on ships and other marine infrastructures. This struggle led to the use of dangerous substances such as arsenic and tributyltin. More recently, in the past 50 years, efforts have been made to stop the use of these biocides because of the damaging effect they have on the environment. Since then, less damaging paints and coatings characterized by being soluble and not persistent in the environment are used, such as mixtures with copper. In this way, the coatings are still biocidal, but do not cause nearly as much harm to the environment because they will not persist in the ecosystem or cause significant harm to organisms other than the fouling ones. In the present study, a mixture was created with technical Cashew Nut Shell Liquid (tCNSL) and titanium dioxide (TiO₂) nanoparticles, with the aim of creating an anti-fouling coating capable of preventing the growth of a fouling organism, Amphibalanus amphitrite on a substrate. The coating was prepared and two Amphibalanus amphitrite in their cyprid stage were dispensed into each well, and set at room temperature. The barnacles were monitored in order to see if the coating prevented them from settling. Adhesion was not observed, even in the control sample, so no significant data was collected.
