“…Nanocomposite systems, based on PDMS-nanorods of ZnO, β–MnO 2 and GO-Al 2 O 3 were investigated and characterized by WCA (water contact angle) static and dynamic (hysteresis) and surface’s mechanical properties (impact, mandrel bending, and cross-cut test) to check the coatings’ durability, adhesion strength to the substrate and elasticity [ 28 , 29 , 30 ]. Authors showed that each nanocomposite exhibited a nanorod optimum amount, within the range 0.5 wt% and 1.0 wt%.…”

Mechanical Properties of Protective Coatings against Marine Fouling: A Review

2021

The accumulation of marine organisms on ship hulls, such as microorganisms, barnacles, and seaweeds, represents a global problem for maritime industries, with both economic and environmental costs. The use of biocide-containing paints poses a serious threat to marine ecosystems, affecting both target and non-target organisms driving science and technology towards non-biocidal solutions based on physico-chemical and materials properties of coatings. The review reports recent development of hydrophobic protective coatings in terms of mechanical properties, correlated with the wet ability features. The attention is focused mainly on coatings based on siloxane and epoxy resin due to the wide application fields of such systems in the marine industry. Polyurethane and other systems have been considered as well. These coatings for anti-fouling applications needs to be both long-term mechanically stable, perfectly adherent with the metallic/composite substrate, and capable to detach/destroy the fouling organism. Prospects should focus on developing even “greener” antifouling coatings solutions. These coatings should also be readily addressable to industrial scale-up for large-scale product distribution, possibly at a reasonable cost.

“…Previously cited authors' works, along with the works of [13,30,35,36], are precious in evidencing that SH coatings can be viewed as a promising and interesting solution for fouling and corrosion control, although results were obtained in model biological environments and in time windows less than a month. Concerning the approach to a real seawater environment, other authors [37,38] obtained noteworthy foul control results in a time window greater than a month. Hydrodynamic effects were investigated in a model environment with bacteria and diatoms up to 10 days [38].…”

Superhydrophobic Coatings from Recyclable Materials for Protection in a Real Sea Environment

2019

Recyclable materials can be referred to as both those materials directly recycled from wastes and those derived from any kind of transformation before use. Highly water repellent coatings with wettability properties, known as superhydrophobic (SH), are related to surfaces with contact angles above 150° and a very small hysteresis. The small area available for these surfaces when in contact with water can be exploited in many applications in which interactions with an aqueous environment are usually desirable to be avoided, like for protection and friction reduction in a marine environment. SH coatings under investigation have been prepared starting from recyclable materials with the aim to provide a sustainable and low cost solution, with potential application to large surfaces in a marine environment. Wetting studies, surface characterization, and electrochemical tests show how these surfaces can be used in terms of fouling prevention and the protection of metals in underwater conditions.

“…Moreover, the International Maritime Organization (IMO, 2003) banned the use of tinrelated compounds for fouling resistance on ship hull coatings. The worldwide ban accompanied by utilizing toxic antifouling paints have driven modern research toward eco-friendly solutions particularly, FR technology [61][62][63][64][65][66][67] . Controlling the size and morphology of nanomaterials can improve the performance of nanocomposite [68][69][70] .…”

A global interest was awarded to study the natural superhydrophobic surfaces since the description of the Lotus Effect by Barthlott and Neinhuis in 1997. Natural biomimetic surface merits of micro/nano-roughness, water contact ˃ 150°, sliding angles ˂10°, and minimized free-energy characteristics would motivate the dynamic fabrication of superhydrophobic surfaces. This critical review introduces an architectural panorama of numerous structural designs of natural superhydrophobic surfaces. Also, it discussed the fundamentals of self-cleaning and wetting theories to develop superhydrophobic structures. This progress review concentrates on superhydrophobic materials' applications for self-cleaning marine antifouling surfaces. It introduced an in-depth understanding of the structural design-superhydrophobic property relationship of the natural nano-wettable surfaces. It is technically first to shed light on the inner basics and platform for surface non-wettability and facilitates the way for design biomimetic self-cleaning antifouling surfaces.
