Abstract

An antifouling tile includes a tile blank having a first surface and a second surface opposite the first surface. The antifouling tile also includes a plurality of photocatalytic particles mounted to the first surface of the tile blank. The antifouling tile further includes an ultraviolet (UV) light source mounted to the second surface of the tile blank. The UV light source activates the plurality of photocatalytic particles to prevent biofouling of the tile blank.
