Aluminum alloy is widely used in many fields for its excellent performance. However, in practical application, aluminum alloy is easy to become corroded and be invalidated, owing to the influence of environmental factors. Some pollutants or corrosive media q5 its surface adhesion will further deepen the failure rate of aluminum alloy, resulting in a large amount of workforce waste, waste of material and financial resources, and energy consumption. So the anti-corrosion and anti-fouling treatment of aluminum alloy surfaces to expand their practical application range and reduce energy loss are of great significance. In this paper, we first summarize the types of anti-corrosion and anti-fouling coatings on aluminum alloy surfaces. We found that superhydrophobic coating has attracted widespread attention recently because of its surface’s non-wetting and low surface energy characteristics. The superhydrophobic coating refers to a coating with a water contact angle on its surface greater than 150° and a sliding angle of less than 10°. Preparing superhydrophobic coatings on the surface of aluminum alloy can improve the corrosion resistance and anti-pollutant adhesion ability at the same time. Therefore, in the following part of the review, the preparation methods of superhydrophobic coatings on aluminum alloy surfaces for anti-corrosion and anti-fouling and the significant problems encountered in the practical application of the superhydrophobic coating on aluminum alloy surfaces, such as poor anti-corrosion durability and poor mechanical stability, and the existing methods to solve these critical problems, are summarized and discussed in detail. Finally, we put forward some new solutions to solve these vital issues.

“…Enhancing the barrier properties and anti-corrosion capabilities of polymer coatings often involves adding appropriate anticorrosion fillers. [16][17][18][19][20][21][22][23][24][25] Polyurethane (PU) coatings offer several significant advantages over conventional coatings like nickel (Ni) coating, chemical conversion films, and plating metal layers: (i) Flexibility and Durability: PU coatings are highly flexible, preventing cracks and extending the life of the coating under mechanical stress; (ii) Chemical Resistance: PU coatings provide excellent resistance to chemicals, oils, and fuels, essential for aircraft exposed to various substances; (iii) Environmental Compliance: PU coatings can be formulated to meet stringent environmental regulations, reducing volatile organic compound (VOC) emissions; (iv) Weight Reduction: PU coatings add less weight to aircraft, beneficial for fuel efficiency and performance; (v) Enhanced Adhesion and Flexibility: PU coatings adhere better to various substrates and can flex without cracking, unlike some metal-based coatings; (vi) Simplified Application Process: PU coatings can often be applied using simpler and more versatile methods, reducing application time and cost. Recent research focuses on enhancing PU properties by incorporating 2D layered nanocomposites, particularly graphitic carbon nitride (GCN) and silanized tantalum nitride (TaN) nanoparticles.…”

Nanocomposites containing impermeable two‐dimensional materials are of significant interest for protecting metals against corrosion. Incorporating 4‐aminobutyltriethoxysilane (ABES) functionalized tantalum nitride (TaN) into a coating matrix enhances the barrier effect due to TaN's notable chemical and thermal stability. When integrated with graphitic carbon nitride (GCN) in polyurethane (PU), functionalized TaN significantly improves corrosion resistance and fire‐retardant capabilities. Electrochemical evaluations of aluminum coated with varying amounts of functionalized TaN/GCN in PU demonstrated substantial enhancements in protective behavior in chloride environments. The PU nanocomposite exhibited superior flame retardancy, with significant reductions in peak heat release rate (PHRR), total heat release (THR), and total smoke production (TSP) compared to pure PU. Flame retardancy tests demonstrated increased thermal stability, attributed to the synergistic effects between GCN and silanized TaN. Electrochemical impedance spectroscopy (EIS) measurements showed a high coating resistance of 8.89×1011 Ω cm2 for PU/functionalized TaN/GCN, even after 40 days of electrolyte exposure. Additionally, the PU/functionalized TaN/GCN coating demonstrated exceptional water repellency, indicated by a water contact angle (WCA) of 164°. Mechanical tests revealed that PU/functionalized TaN/GCN exhibited favorable adhesion strength and hardness, maintaining integrity even under prolonged immersion. These findings suggest that this nanocomposite is a promising coating component for aerospace applications. The integration of functionalized TaN/GCN within the PU matrix presents a novel approach to developing multifunctional coatings with enhanced performance across various metrics essential for aerospace materials.
