Investigating the role of inspiration from nature in the production of anti-moss coatings for marine vessels

In recent years, the increase in marine pollution and the challenges caused by the growth of algae and moss on the surfaces of marine vessels have increased the need to develop effective anti-moss coatings. Marine biological fouling is the process where marine microorganisms adhere to and accumulate on the surfaces of underwater equipment, significantly affecting marine industries and operations. Studies have shown that a ship lacking sufficient anti-fouling measures can experience a ۴۰% increase in fuel consumption when operating in the ocean for six months, along with an ۸۶% loss in power due to substantial calcium buildup. Currently, the most effective and straightforward method to mitigate the impacts of biological fouling is through the use of antifouling coatings. Over the last ten years, the evolution of these coatings has progressed from organotin compounds (such as TBT) to those incorporating heavy metals like cuprous oxide, and more recently to polymer-based coatings. Among these, polymeric coatings are considered more environmentally friendly, as they do not inflict lasting harm on marine ecosystems and offer flexibility in their chemical structure and formulation. Inspiration from nature has been proposed as a rich source for the design and production of these types of coatings. In this study, natural patterns and features found in marine environments, such as the skin of some fish and marine plants, are examined. These patterns can be effective in creating coatings with anti-adhesion properties and reducing algae growth. The results of this study show that by using nanotechnology and inspiration from nature, advanced coatings can be produced that, in addition to reducing the costs of vessel maintenance, also reduce negative environmental impacts.
