Modern approaches to marine antifouling coatings
نویسنده
چکیده
Marine structures such as platforms, jetties and ship hulls are subject to diverse and severe biofouling. Methods for inhibiting both organic and inorganic growth on wetted substrates are varied but most antifouling systems take the form of protective coatings. Biofouling can negatively affect the hydrodynamics of a hull by increasing the required propulsive power and the fuel consumption. This paper reviews the development of antifouling coatings for the prevention of marine biological fouling. As a result of the 2001 International Maritime Organization (IMO) ban on tributyltin (TBT), replacement antifouling coatings have to be environmentally acceptable as well as maintain a long life. Tin-free self-polishing copolymer (SPC) and foul release technologies are current applications but many alternatives have been suggested. Modern approaches to environmentally effective antifouling systems and their performance are highlighted. © 2006 Elsevier B.V. All rights reserved.

Chitosan-zinc oxide nanocomposite coatings for the prevention of marine biofouling.
Marine biofouling is a worldwide problem affecting maritime industries. Global concerns about the high toxicity of antifouling paints have highlighted the need to develop less toxic antifouling coatings. Chitosan is a natural polymer with antimicrobial, antifungal and antialgal properties that is obtained from partial deacetylation of crustacean waste. In the present study, nanocomposite chitos...
متن کاملBiocides for Antifouling Marine Coatings – Issues in Reactivity, Performance, and Ecotoxicity
For centuries, owners of private, commercial and military sea vessels have attempted, with varying degrees of success, to surface treat their underwater hulls with coatings to prevent the adhesion and/or growth of large fouling organisms that cause severe drag, reducing vessel speed and maneuverability, and increasing fuel consumption. Two major approaches are currently under development: (1) “...
متن کاملMarine organisms: A potential source of natural antifouling metabolites
Marine organisms have been proven to be excellent sources of environmentally benign biogenic compounds. These metabolites have received much attention because of their pharmacological and antifouling activites. Biofouling process is known to cause serious problems to the submerged structures. Many countries have ratified an international treaty to ban the application of antifouling coatings bas...
متن کاملDesigning biomimetic antifouling surfaces.
Marine biofouling is the accumulation of biological material on underwater surfaces, which has plagued both commercial and naval fleets. Biomimetic approaches may well provide new insights into designing and developing alternative, non-toxic, surface-active antifouling (AF) technologies. In the marine environment, all submerged surfaces are affected by the attachment of fouling organisms, such ...
