“…Bioinspired strategies for antibiofouling materials have been developed by mimicking the topology of natural materials or by employing biobased substances. [ 22–34 ] Nanostructured cauliflower‐like [ 35 ] or nanoflower‐like [ 36 ] metallic substrates were resistant to platelet adhesion or protein adsorption due to their superomniphobic properties. Antifouling against bacterial adhesion was obtained on shark skin‐like [ 37 ] or ray skin‐like [ 38 ] microtopography on polydimethylsiloxane (PDMS) elastomers.…”

Biofouling on surfaces immersed in aquatic environment induces catastrophic corrosion of metallic materials in petrochemical infrastructures, maritime facilities, and power plants. To combat the synergistic effect of biofouling and corrosion on the deterioration of metallic materials, smart coatings possessing a dual function of antibiofouling and anticorrosion properties are needed. Herein, redox‐responsive copolymer conjugates are synthesized and employed as coatings with the dual function of biofouling and corrosion mitigation. The dual function of copolymers is attributed to fluorinated units and the corrosion inhibitor 2‐mercaptobenzothiazole (MBT) conjugated via disulfide linkages. Indeed, the disulfide linkages can be cleaved in a reducing environment, yielding controlled release of the corrosion inhibitor MBT during corrosion process. The antibiofouling action against protein adsorption and algal attachment is enabled by cooperation of the repellent characteristic of fluorinated moieties and the biocidal effect of conjugated MBT.

“…Therefore, efforts have been made to control biofouling by developing alternative environmentally friendly strategies that could either substitute or boost the activity of currently used, toxic biocides. Different strategies are being explored, including the use of non-bionic anti-fouling technologies (Tian et al, 2021) and the application of bioinspired strategies, such as bioinspired polymeric anti-fouling coatings, and biomimetic surface microtopographies (Chen et al, 2021;Tian et al, 2021). The simultaneous use of multiple antifouling approaches that act synergistically has been proposed in order to reduce the toxicity and increase the effectiveness of the anti-fouling coatings (Xie et al, 2020).…”

“…Due to the need for eco-friendly compounds and strategies to substitute the traditional highly toxic anti-fouling biocides, current efforts are also focused on the development of innovative coatings and the examination of the effectiveness of novel natural products with anti-fouling activity (e.g., Maréchal and Hellio, 2009;Nir and Reches, 2016;Chen et al, 2021). Polymers and nanoparticles (Kavouras et al, 2019;Gutner-Hoch et al, 2018;Gu et al, 2020), but also enzymes and peptides have been applied for anti-fouling purposes at laboratory scale.…”

“…Polymers and nanoparticles (Kavouras et al, 2019;Gutner-Hoch et al, 2018;Gu et al, 2020), but also enzymes and peptides have been applied for anti-fouling purposes at laboratory scale. However, their high costs and problematic production prevented large-scale testing and application (Ma et al, 2018;Chen et al, 2021). The incorporation of natural functional compounds into the matrix of the coatings has also been explored, although only a few of them have been tested under natural conditions.…”

Evaluation of the Anti-fouling Efficacy of Bacillus licheniformis Extracts Under Environmental and Natural Conditions

et al. 2021

There is an increasing interest in developing innovative coatings and testing natural products with anti-fouling activity to substitute current highly toxic biocides that have a harmful impact on marine organisms. Bacillus licheniformis species have shown different anti-biofilm and anti-fouling activities in vitro, but so far, its efficacy in field trials has not been tested. For this purpose, the capacity of different extracts of B. licheniformis NCTC 10341T to prevent micro and macro-fouling was first tested in vitro. The methanol cell extract (MCE) inhibited bacterial biofilm formation without significantly affecting planktonic growth and displayed a significant efficacy to prevent larval settlement of the macro-fouler Bugula neritina in vitro without inducing lethality. Additionally, the MCE presented low toxicity against the non-target species Artemia salina. The B. licheniformis MCE was then incorporated in a self-polishing paint at 2 and 5% w/w and tested in a static immersion experiment in the Gulf of Aqaba (northern Red Sea) for 180 days. Fouling coverage decreased by 30% in the 5% MCE-treated panels in comparison with the control panels. Differences in the anti-biofilm activity of the extracts depending on the culture medium highlight the importance of the strict control of culture conditions for the production of biomass with stable bioactive activity. The results indicate the potential of B. licheniformis NCTC 10341T crude extracts for environmentally friendly anti-fouling applications, although a deeper characterization of the bioactive compounds present in the B. licheniformis MCE and its mode of action is required to allow strict control of the activity of the extracts to achieve large-scale industrial production.

“…There are many kinds of antifouling coatings [4]. The mature antifouling coatings include low surface energy antifouling coatings [5], self-polishing antifouling coatings [6] and amphiphilic antifouling coatings [7,8], etc. These coatings are widely used, and their functional effects and economic benefits are indispensable.…”

The matching application of silicone antifouling coating and epoxy primer is a major problem in engineering. Novel epoxy-modified silicone tie-coating was prepared to tie epoxy primer and silicone antifouling coating. Firstly, N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane was mechanically mixed with bisphenol A epoxy resin to form silylated epoxy resin, then the silylated epoxy resin was uniformly mixed with hydroxy-terminated polydimethylsiloxane and a curing agent and catalyst for coating. An infrared spectrometer, differential scanning calorimeter and tensile tests were used to investigate the chemical structure, phase transition temperature and mechanical properties of the tie-coatings. The interlaminar adhesion of the matching coating system was tested and analyzed by a peel-off test and a shear test. Fracture morphology was observed by scanning using an electron microscope. The results showed that crosslinking density of the tie-coating, the elastic modulus and the tensile strength of the coating increased with an increasing epoxy content, but fracture elongation decreased. The shear strength of the matching coating system is 0.37 MPa, and it shows a good tie performance. The maximum anti-peeling rate of the tie-coating on the epoxy primer reaches 100%.
