- Abstract
Antifouling is necessary to prevent the fouling of marine organisms on ship surfaces in seawater. Foul release (FR) coatings are considered an alternative to commercial antifouling coatings as eco‐friendly coating materials that can prevent toxic biocide emissions. However, the evaluation of FR coatings for antifouling is extremely complicated owing to their foul‐releasing mechanism with diverse surface properties. Therefore, a reliable laboratory simulation of the actual seawater immersion condition is required. Silicon‐based FR coatings with several additives were prepared to evaluate the reliability of a laboratory fouling test. To simulate the marine foulant removal efficiency of an FR coating surface based on the ship speed, a circulating seawater channel was applied. Laboratory test showed a similar tendency as the seawater immersion. From the results, laboratory‐scale microalgae fouling tests and circulating seawater channel tests are considered suitable for evaluating the antifouling performance of FR coatings.
