“…The chemical composition and bonding state of the SiO 2 @ PSDP coating were further verified by X-ray photoelectron spectroscopy (XPS) and illuminated the mechanism of wettability change. As shown in Figure 2a, the XPS survey spectrum from PSDP is mainly composed of C, O, F, and S elements, 25,51 while the spectrum for SiO 2 @PSDP shows obvious O 1s (40.08%, at. %) and Si 2p (19.09, at.…”

Sulfur-rich polymers generated from the inverse vulcanization of elemental sulfur with unsaturated monomers have emerged as a family of organic polymers with unique functionalities and broad potential applications. First described in 2013, inverse vulcanization is still in its infancy regarding its fundamental development, property exploration of the resultant polymers, and practical utilizations. Herein, the robust properties of sulfur-rich composites generated by inverse vulcanization with SiO2-embedded elemental sulfur are revealed, furnishing superhydrophobicity with static water contact angles of up to 154.7 ± 1.8°, a high anticorrosive effect of 98.9% protection efficiency for Mg alloy in 3.5 wt % NaCl solution, and a good antibacterial performance against Escherichia coli (81%) and Staphylococcus aureus (75%). The resulted composite also shows excellent self-cleaning functionalities. This has not only expanded the properties/functionalities and applications of the sulfur-rich polymers resulting from inverse vulcanization but also provided low-cost alternatives to superhydrophobic coating materials for practical applications.

“…In most practical cases, even slightly abrasive forces or easily rubbing can simply damage or ruin the nanoscale structure of treated surfaces and reduce the non-wetting performance of coatings. More recently, many reports evaluated the mechanical stability of the super-repellant surfaces via an abrasion test by providing a 100 g load placed on 800#, , 1000#, , 2000#, , and 3000# grit sandpapers. Hence, to assess the mechanical durability of the coatings, abrasion tests were conducted using a 600# grit sandpaper with 10 cm length serving as an abrasive surface.…”

Surfaces with special wettability have aroused lots of attention due to their broad applications in many fields. In this work, we systematically report selective and various fabrications of nanofluids based on readily available materials such as SiO 2 nanoparticles and polydimethylsiloxane to create superhydrophobic, superoleophobic, superhydrophilic/superoleophobic, and underwater superoleophobic coatings. The efficiency of prepared coatings is investigated on mineral rock plates as porous substrates via the straightforward and cost-effective solution-immersion technique. The static water contact angle of 170°, effortless bouncing of water droplets, and self-cleaning property with a near zero tilt of the solid surface are signs of a high-performance superhydrophobic surface treated with the polydimethylsiloxanemodified silica nanofluid. The superamphiphobic nanofluid coating endows a non-adhesive feature to the rock surface by which the water and oil droplets can be freely moved on the surface with negligible tilt and are easily detached by a needle tip without leaving a trail. What is more, the superamphiphobic surface provides excellent anti-fouling and self-cleaning properties, along with convenient rolling-off behavior with sliding angles ≤8°for various oily liquids. Also, the obtained superhydrophilic/superoleophobic surface exhibits dual superoleophobicity both in air and underwater. These diverse coatings can be used on different substrates, which notably expand the scope of applications. As a case, we employed the superhydrophilic/superoleophobic coating on a stainless-steel mesh for oil−water separation. The separation efficiency of above 99% for various oil−water mixtures confirms the superior oilshielding and water-affinity properties of the coating. All of the abovementioned advantages, combined with significant chemical and mechanical stability and high-pressure−high-temperature resistance of the treated surfaces, indicate that the prepared multifunctional coatings will hold great potential in a variety of practical and industrial applications.

“…The traditional manufacturing techniques, machining and casting, are generating a large amount of waste materials. Therefore, to achieve environmental sustainability researchers have begun to pay more attention to other methods, such as laser cladding, producing functional coatings with improved properties, while reducing the waste material and improving the costs associated [32][33][34][35][36][37]. The cold spray process has also been proposed as a sustainable, versatile method that can be used with various substrates for multiple applications.…”

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.
