“…Some low surface energy coatings have also been prepared with modified acrylic resin and nano-SiO 2 [89]. However, accumulated fouling organisms are not as easily released as anticipated [37,90,91]. In addition, this method has many deficiencies, such as high cost, poor mechanical properties, [23].…”

“…Early attempts to control the problem using biocides are now strongly discouraged due to their detrimental impact on the ecosystem. Systematic studies on conventional coatings support the conclusion that microorganisms adhere weakly to mechanically weak surfaces (and vice versa), but those coatings tend to be peeled off quickly and need to be reapplied frequently [21]. Nanoscale sculpturing at the vessel surface is a promising strategy to create non-toxic fouling release coatings [22,23].…”

In view of the continuous decline in fossil fuel reserves, at a time when energy demands are steadily increasing, a diverse range of emerging nanotechnologies promise to secure modern solutions to the prehistoric energy problem. Each one of those distinct approaches capitalizes on different principles, concepts and methodologies to address different application requirements, but their common objective is to open a window to a sustainable energy future. Consequently, they all deserve substantial (though not necessarily equal) consideration from the scientific and engineering community. In this review we present bottom-up strategies that show great promise for the development of a new generation of advanced materials for energy applications without compromising the public safety or the environment.

“…Foul-release coatings (FRCs), i.e. coatings based on silicone elastomers with low surface free energies, are generally only successful for fast-moving vessels, as the decrease in adhesion strength facilitates removal at speeds greater than 20 knots (Brady 2001). However, diatoms have higher attachment strength on hydrophobic surfaces (Holland et al 2004 (a combination of micrometre-scale and nanometre-scale roughness, along with a low surface free energy, resulting in high water contact angles greater than 150 • ) have been studied for their AF performance (Zhang et al 2005;Scardino et al 2009a,b) and are known to exhibit reduced viscous drag due to slip associated with a layer of air trapped at the liquid-solid interface.…”

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, surfaceactive antifouling (AF) technologies. In the marine environment, all submerged surfaces are affected by the attachment of fouling organisms, such as bacteria, diatoms, algae and invertebrates, causing increased hydrodynamic drag, resulting in increased fuel consumption, and decreased speed and operational range. There are also additional expenses of dry-docking, together with increased fuel costs and corrosion, which are all important economic factors that demand the prevention of biofouling. Past solutions to AF have generally used toxic paints or coatings that have had a detrimental effect on marine life worldwide. The prohibited use of these antifoulants has led to the search for biologically inspired AF strategies. This review will explore the natural and biomimetic AF surface strategies for marine systems.
