Application of Silicone and Fluoropolymer in Marine Antifouling Coatings

Marine biofouling is a sticky problem. As the enhancement of environmental awareness, the development of environmentally friendly marine antifouling systems has become the most important task in this field. Nowadays, non-toxic silicone/fluorine-based marine antifouling coatings have attracted considerable attention. In this paper, the recent progress in the silicon/fluorine-based low surface energy antifouling coatings have been reviewed, and particularly, the fouling release coatings based on biomimetic technology have been described. The effects of surface properties such as physical/chemical properties and structure characteristics on the settled organisms are investigated. In addition, the silicone-based antifouling coatings modified by amphiphilic additives are introduced. Finally, the future trend of the antifouling coatings is given.
