of superhydrophobic coatings in the field of corrosion protection has attracted enormous attention because of its unique interfacial three phase contacts and excellent water resistance. [10][11][12][13] Superhydrophobic coatings are described by water contact angle (WCA) greater than 150° and water sliding angle (WSA) lower than 10°. Inspired by nature, the artificial superhydrophobic coatings exerting advantages in antifogging, antibacterial, anti-icing, oilwater separation, and water purification are fabricated by constructing appropriate hierarchical rough structures and introducing low surface energy materials.

Corrosion is an inevitable and thorny issue in various fields, resulting in materials degradation, environmental pollution, economic loss, and even emergency safety accidents. Owing to the special surface functions, superhydrophobic coatings are regarded as a promising strategy towards corrosion inhibition. However, the large‐scale and real‐world applications of superhydrophobic coatings are restricted by the mechanical and chemical weaknesses. Herein, a fluorine‐free dual‐layer microarc oxidation/superhydrophobic coating with mechanochemical stabilization is fabricated for corrosion protection. The dual‐layer coating maintains superhydrophobicity under ultraviolet irradiation (15 d), different pH values (1–14), different temperatures (0–100 °C) and abrasion test (180 cycles). Its impedance modulus at the lowest frequency is increased by more than six orders of magnitude than that of the pristine substrate, and the corrosion inhibition efficiency value is calculated as 99.999%. The enhancement of surface multifunctions is attributed to the synergistic effects of microarc oxidation layer and superhydrophobic layer. The as‐prepared robust dual‐layer coating with excellent properties is expected to have potential applications in material protection fields.

“…Many studies have indicated that the SLIPS with a liquid layer possessed excellent antifouling performance. 16,18,47,48 In this work, Pseudoalteromonas sp., a typical marine bacteria, was utilized to evaluate the bacterial settlement on different surfaces. To improve the adhesive force and mechanical properties of the organogel, triethoxyvinylsilane and SiO 2 were added into the organogel.…”

Microbiologically influenced corrosion (MIC) accelerates the corrosion and degradation of metal materials due to the settlement of microorganisms on the surface. However, environmentally friendly and efficient methods to fabricate antifouling and anticorrosion surfaces are still lacking. Inspired by Nepenthes, a slippery liquid-infused porous surface (SLIPS) has been proven to be an efficient way to inhibit settlement of microorganisms on the metal surface and the following MIC due to the existence of a mobile defect-free lubricant layer. However, the stability of the lubricant layer and substrate of the SLIPS prevented its long-term antifouling and anticorrosion application. Herein, a highly stable slippery organogel was fabricated by depositing a homogeneous mixture of PDMS (base and curing agent), silicone oil, triethoxyvinylsilane, and SiO2 on Q235 and curing in an oven. Triethoxyvinylsilane was not only able to cross-link with the curing agent of PDMS through hydrosilylation but also able to interlink the organogel and Q235 through condensation between the −OH of the metal surface and hydrolyzed siloxane. As a result, the adhesion force between the organogel without triethoxyvinylsilane and the substrate (0.45 MPa) increased to 1.50 MPa for the organogel with triethoxyvinylsilane and SiO2. Also, the tensile strength of the organogel without SiO2 (0.97 MPa) increased to 3.88 MPa for the organogel with 2 wt % SiO2 because of the high elastic modulus of SiO2, which was important to improving its stability under external force. In addition, the organogel showed stable oil distribution and slippery performance after spinning at 4000 rpm for 30 s. Then, the bacterial settlement demonstrated that the organogel could effectively inhibit Pseudoalteromonas sp. settlement on the substrate under both static and dynamic conditions. Finally, an electrochemical test indicated that the MIC could be effectively mitigated by the organogel. This study provides an efficient method to fabricate a highly stable slippery surface on a metal surface for its potential application in mitigating MIC.

The need for nontoxic antifouling coatings has encouraged material scientists to develop a class of organic coatings for diverse applications. As a versatile thermosetting resin and well known for coating application, antifouling characteristics have been integrated into epoxy along with anticorrosion and adhesive functions. Accordingly, both micro-and macro-biofoulings have been successfully controlled by using epoxy-based antifouling coatings. Epoxy nanocomposites, silicon-grafted epoxy, epoxy-aided conductive polymer blends, and nanocomposites are important antifouling epoxy variants far and wide examined in developing epoxy-based coatings. Besides, some purpose-specific multifunctional smart coatings based on epoxy with antifouling features are used to integrate several functions into one material. This review discusses various types of epoxy-based antifouling coatings. The ability of nanomaterials, siloxanes, and conducting polymers to induce antifouling activity into the epoxy and corresponding antifouling mechanisms is also covered. The review concludes with the enormous potential of antifouling epoxy coatings as cost-effective, environmentally sustainable solution to biofouling in diverse industrial applications. Finally, the future ahead of antifouling epoxy coating is patterned.
