Antifouling (AF) nanocoatings made of polydimethylsiloxane (PDMS) are more cost-efficient and eco-friendly substitutes for the already outlawed tributyltin-based coatings. Here, a catalytic hydrosilation approach was used to construct a design inspired by composite mosquito eyes from non-toxic PDMS nanocomposites filled with graphene oxide (GO) nanosheets decorated with magnetite nanospheres (GO–Fe3O4 nanospheres). Various GO–Fe3O4 hybrid nanofillers were dispersed into the PDMS resin through a solution casting method to evaluate the structure–property relationship. A simple coprecipitation procedure was used to fabricate magnetite nanospheres with an average diameter of 30–50 nm, a single crystal structure, and a predominant (311) lattice plane. The uniform bioinspired superhydrophobic PDMS/GO–Fe3O4 nanocomposite surface produced had a micro-/nano-roughness, low surface-free energy (SFE), and high fouling release (FR) efficiency. It exhibited several advantages including simplicity, ease of large-area fabrication, and a simultaneous offering of dual micro-/nano-scale structures simply via a one-step solution casting process for a wide variety of materials. The superhydrophobicity, SFE, and rough topology have been studied as surface properties of the unfilled silicone and the bioinspired PDMS/GO–Fe3O4 nanocomposites. The coatings’ physical, mechanical, and anticorrosive features were also taken into account. Several microorganisms were employed to examine the fouling resistance of the coated specimens for 1 month. Good dispersion of GO–Fe3O4 hybrid fillers in the PDMS coating until 1 wt % achieved the highest water contact angle (158° ± 2°), the lowest SFE (12.06 mN/m), micro-/nano-roughness, and improved bulk mechanical and anticorrosion properties. The well-distributed PDMS/GO–Fe3O4 (1 wt % nanofillers) bioinspired nanocoating showed the least biodegradability against all the tested microorganisms [Kocuria rhizophila (2.047%), Pseudomonas aeruginosa (1.961%), and Candida albicans (1.924%)]. We successfully developed non-toxic, low-cost, and economical nanostructured superhydrophobic FR composite coatings for long-term ship hull coatings. This study may expand the applications of bio-inspired functional materials because for multiple AF, durability and hydrophobicity are both important features in several industrial applications.

“…1−4 It can deteriorate the component surfaces, increase the fuel consumption by increasing the ship hull drag, and thus result in higher economic losses. 5,6 Specifically, biofouling can accelerate the corrosion rate of metals and reduce the lifespan of facilities used under the sea, as the settlement of fouling organisms can change the localized environment (oxygen level and pH value) and promote chemical/electrochemical corrosion, i.e., microbially influenced corrosion. 7−10 Therefore, the development of anticorrosion and antifouling materials and technologies is of great significance for marine engineering.…”

Biofouling and corrosion of underwater equipment induced by marine organisms have become major issues in the marine industry. The superior corrosion resistance of Fe-based amorphous coatings makes them suitable for marine applications; however, they have a poor antifouling ability. In this work, a hydrogel-anchored amorphous (HAM) coating with satisfactory antifouling and anticorrosion performance is designed, utilizing an interfacial engineering strategy involving micropatterning, surface hydroxylation, and a dopamine intermediate layer to increase the adhesion strength between the hydrogel layer and the amorphous coating. The as-obtained HAM coating exhibits exceptional antifouling properties, achieving 99.8% resistance to algae, 100% resistance to mussels, and excellent biocorrosion resistance against Pseudomonas aeruginosa. Antifouling and anticorrosion performance of the HAM coating was also explored by conducting a marine field test in the East China Sea, and no signs of corrosion and fouling are observed after 1 month of immersion. It is revealed that the outstanding antifouling properties stem from the killing−resisting−camouflaging trinity that resists organism attachment across different length scales, and the excellent anticorrosion performance originates from the remarkable barrier of the amorphous coating against Cl − ion diffusion and microbe-induced biocorrosion. This work presents a novel methodology for designing marine protective coating with excellent antifouling and anticorrosion properties.

“…For instance, MIC by sulfate-reducing bacteria (SRB) was explained by the cathodic depolarization theory in early days [5][6][7]. Microbes can also produce corrosive metabolite such as organic acids and corrosive gases [8,9], or change oxygen concentration and pH at the solution/metal interface to enhance local corrosion [10][11][12]. Another key mechanism that has been more recently proposed to explain MIC is extracellular electron transfer (EET), which refers to the electron exchange process between microorganisms and extracellular electrodes such as metals [13][14][15][16].…”
