Adhesion of foulings on surface energy of silicone rubber coatings

All antifouling paints in use today are effective because toxic ingredients based on heavy metals are included in their formulation, the environmental effects of organotins in seawater have been a topic of much interest and concern in recent years. This study has found that the material of rich silicone rubber on mating surface based on the low dispetsive component of surface energy makes barnacle settling on them unable to attach petntanently and is removed by moving water. The material permits only small amounts of fouling to attach, such as algae, Ciona intestinalis, because the high polar interaction of coating surface may absorb water to form water film in sea, and cause very low adhesion of the fouling species.
