“…Huang et al 14 fabricated a two-layered Cu/Al 2 O 3 composite coating via cold spray, which exhibits a high adhesion strength (~ 20 MPa) to a steel substrate and good anti-biofouling resistance (85%) against barnacles, diatoms and mussels. Recently, Tian et al 15 developed a plasma-sprayed Cu-Ti coatings with microscale Cu/Ti laminated microstructure on a steel substrate, which also demonstrates excellent antifouling properties against Escherichia coli (E. coli) bacteria because of Cu ions release and self-polishing effect. Unfortunately, the corrosion resistance of these coatings is not satisfactory, limiting the durability in services.…”

Fe-based amorphous coatings with outstanding corrosion resistance are promise for marine applications. However, these coatings encounter a great challenge of biofouling in marine environments. Inspired by the unique micro-nano hierarchical structure of shark skin with excellent antifouling properties, in this paper, we construct a bioinspired Fe-based amorphous coating with killing-resisting dual-effect via proper surface modifications, i.e., the modification with micro-patterned nanostructured Cu2O fibers (killing effect), followed by the modification with superhydrophobic surface (resisting effect). As a result, the modified amorphous coating exhibits impressive antifouling properties, achieving 98.6% resistance to Nitzschia closterium f. minutissima, 87% resistance to Bovine serum albumin protein and 99.8% resistance to Pseudomonas aeruginosa, respectively. The remarkable antifouling performance is attributed to a synergistic antifouling mechanism from both resisting effect and killing effect, wherein the superhydrophobic surface provides a barrier to resist protein adsorption, while the patterned nanostructured Cu2O fibers supply Cu+ ions to kill bacterial cells. In addition, the modified amorphous coating also exhibits excellent mechanical robustness, which ensures the durability of the Fe-based amorphous coating in practical services. This work may promote the development of new durable metal-based coatings integrated with anti-fouling and anti-corrosion properties.

“…The widely used copper-plating process uses cyanide ions, which can cause serious environmental pollution problems [ 27 , 28 ]. Other methods, such as plasma treatment with oxygen, chemical vapor deposition, and ammonia plasma, require complex equipment and procedures [ 29 , 30 , 31 , 32 ]. Therefore, to widely apply the antibacterial properties of copper, a new method to solve these problems is important.…”

Copper Surface Treatment Method with Antibacterial Performance Using “Super-Spread Wetting” Properties

In this work, a copper coating is developed on a carbon steel substrate by exploiting the superwetting properties of liquid copper. We characterize the surface morphology, chemical composition, roughness, wettability, ability to release a copper ion from surfaces, and antibacterial efficacy (against Escherichia coli and Staphylococcus aureus). The coating shows a dense microstructure and good adhesion, with thicknesses of approximately 20–40 µm. X-ray diffraction (XRD) analysis reveals that the coated surface structure is composed of Cu, Cu2O, and CuO. The surface roughness and contact angle measurements suggest that the copper coating is rougher and more hydrophobic than the substrate. Inductively coupled plasma atomic emission spectroscopy (ICP-AES) measurements reveal a dissolution of copper ions in chloride-containing environments. The antibacterial test shows that the copper coating achieves a 99.99% reduction of E. coli and S. aureus. This study suggests that the characteristics of the copper-coated surface, including the chemical composition, high surface roughness, good wettability, and ability for copper ion release, may result in surfaces with antibacterial properties.

“…In recent years, various tin-free self-polishing antifouling coatings, such as acrylic copper [28], acrylic zinc [29], and acrylic silicone [30], have been explored and applied in the marine antifouling areas. Tian et al, developed a micron-level Cu-Ti composite antifouling coating with high mechanical durability and the efficiency against bacteria almost reached 100% [28]. Despite its great antifouling performance, copper antifouling coatings continuously release and accumulate copper ions in docks and ports, causing a hazard to the marine environment and species.…”

Synthesis and Properties of Self-Polishing Antifouling Coatings Based on BIT-Acrylate Resins

Painting antifouling coatings is one of the most important methods to prevent marine biofouling. Acrylic resin is widely used in marine antifouling because of its excellent stickiness, water resistance, and film-forming capabilities. At present, the widely used acrylate antifouling coatings require a high concentration of cuprous oxide as antifoulant. The release and accumulation of copper ions are the main factors affecting the marine environment. In this study, BIT–allyl methacrylate (BM) and zinc acrylate (ZM) were selected as functional monomers copolymerized with methyl methacrylate (MMA) and butyl acrylate (BA) to prepare a series of BIT acrylate antifouling resins. The inhibitory effects of all resins against marine bacteria (S. aureus, V. coralliilyticus, and V. parahaemolyticus), marine algae (Chlorella, I. galbana, and C. curvisetus), and barnacle larvae were studied. Moreover, marine field tests on the BIT modified resin in coastal waters were conducted. The results demonstrate that the grafted BIT–zinc acrylate resin not only exhibits excellent antifouling properties but also a significant self-polishing performance, providing a novel strategy to design a long-term antifouling resin with stable antifoulant release.
