“…Therefore, integrating monotonous superhydrophobicity with multifunctionality characteristics, such as response to magnetic, electric, thermic, and mechanic stimuli, to achieve a wide range of applications has become a new focus. [ 3 ] For example, incorporating conductive materials into a superhydrophobic coating can achieve useful conductors for electrode materials. [ 4 ] Also, superhydrophobic films can be driven or absorbed magnetically by combining the film with magnetic materials.…”

Photothermal superhydrophobic coatings are essential for a variety of applications including anti‐icing and light‐driven self‐propelled motion. However, achieving a flexible and durable superhydrophobic coating with high photothermal efficiency and long‐term stability is still challenging. Herein, a facile and eco‐friendly approach to realizing a superhydrophobic coating with excellent flexibility is proposed. The coating is obtained by spraying titanium nitride (TiN) nanoparticles embedded in polydimethylsiloxane (PDMS) solution onto various substrates. A tight binding between the substrate and nanoparticles occurs that offers the coating the mechanical robustness to endure bending, twisting, abrasion, and tape peeling. The water repellency is retained even after 500 cycles of bending–twisting tests. Combined with the micro–nanoscale porous structure of the surface and plasmonic property of TiN nanoparticles, the coating shows excellent superhydrophobicity and high photothermal conversion properties. The equilibrium temperature of the coating is as high as 130 °C at room temperature under 1 W cm−2 of 808 nm near‐infrared laser irradiation. Due to its flexible property, the coating can be easily applied to irregular surfaces, which, together with the excellent anticorrosion, anti‐icing, and defrosting performances, makes it a reliable resource for multifunctional applications. This work offers a novel technological approach to flexible devices, wearable electronics, and smart textiles.

“…A coating with a contact angle value greater than 150 • in water is a superhydrophobic surface, and presents not only deicing ability, but also stimulichromism, antibacterial activity, flame retardant, and lubricating properties. Coatings with contact angle values less than 90 • are hydrophilic, and when the values are under 10 • , the surface is superhydrophilic [169][170][171]. A large number of coating components can increase or decrease the contact angle, leading to a biomimetic structure that is able to induce special properties and multifunctionality.…”

Starting with a description of the meaning of sustainable coating nowadays, this review presents a selection of methods for sustainable coatings manufacture using raw materials, saving energy and costs. This selection creates an introduction for the coatings performances of intensively investigated coated alloys and their multifunctionality. There are many examples and EU recommendations to be discussed, and we especially chose to introduce sustainable coatings with both industrial and medical functions, such as bioinspired films and coatings on high-entropy alloys, biodegradable metallic alloys, etc. A special focus is on nanotechnology and nanomaterials in green procedures, enhancing coatings’ multifunctionality, introducing green corrosion inhibitors, smart additives, and coatings based on superhydrophobicity. The conclusions and future perspectives of sustainable and multifunctional coatings, as expressions of sustainable advanced materials, are based on important motivations of such studies.

“…The Cassie model, which is further combined with the influence of the chemical properties of the material surface, completes the wetting theory and has theoretical guiding significance for the experiment [5]. Currently, superhydrophobic surface design is mainly based on low surface energy and micro/nanostructures [5][6][7]. Methods for preparing rough surface structures can be divided into two categories.…”

“…Disadvantages of the method include high costs, complex operations, and a lack of general promotion. The other is the "bottom-up" approach that begins with a single small component to produce a complex surface, such as spraying, spin coating, and dipping physical deposition techniques, to prepare superhydrophobic coatings [6,[8][9][10][11]. This method incorporates a viscous resin solution as the matrix and functional powders as the reinforcement to prepare a superhydrophobic composite coating.…”

Superhydrophobic surfaces have great potential for self-cleaning, anti-icing, and drag-reducing because of their water repellency property. However, their super-hydrophobicity is destroyed under mechanical abrasion due to the vulnerability of the delicate surface textures. Here, we demonstrate a strategy to create a robust superhydrophobic surface using MXene and fluoridated silica as functional fillers in epoxy resin. The fluoridated silica produces low surface energy, MXene serves as a wear-resistant phase and epoxy resin is the binding matrix. The composite coating demonstrates a self-cleaning effect to remove particles from the superhydrophobic surface by rolling water droplets. Moreover, the coating exhibits excellent mechanical durability by standing abrasion to maintain super-hydrophobicity. The superhydrophobic composite coating has the advantages of low cost and feasibility and has the potential for expandable industrial promotion.
