scale structures were easily damaged by mechanical impact or deformation, resulting in functional failure. [18][19][20][21][22] To address this fatal drawback, most of the attention was focused on the surface abrasion resistance from rigid friction. [23][24][25][26][27][28] For instance, repair ability and self-healing were exploited to overcome the abrasion damage, suitable organic, or inorganic adhesive were introduced to maintain surface structural integrity or to design the texture of damaged surface similar to the undamaged layer. Therefore, from universal application perspective, it is extremely important to develop suitable adhesive for accommodating various substrates at the specific application environment.Since the strategy that the doublesided adhesive can be used as primer to enhance the wear resistance of topcoat been proposed, [29] many resins have been proved to effectively improve the adhesion of coating. For example, adhesive, such as polydimethylsiloxane (PDMS), [6,30] epoxy resin (EP), [31] polymethyl methacrylate (PMMA), [3,32] polyurethane (PU), [33,34] or polybutadiene (PB), [35] has been demonstrated as one of several promising strategies to enhance its mechanical durability. However, there are still issues about its service life. For example, poor oleophobicity will cause surface contamination and malfunctions when dealing with oil, and surface antifreeze behavior will be directly affected from the synergetic relationship between surface roughness and surface energy. [5,22,32,36,37] Furthermore, despite the development of robust coating as mentioned above, the synergy of adhesives, application integration of composite coating, and its evaluation mechanism at the specific application environment, such as hard flat surface for anti-icing, hard, or soft fiberboard for filter or separation, were rarely reported. Our research group has put forward the idea of fluoroethylene vinyl ether (FEVE) and ethylene vinyl acetate (EVA) composite resin as adhesive. [38] This kind of composite resin is separated in the coating to build a rough structure of primer, which is used to protect the topcoat. However, a tight cross-linked network structure could not be effectively constructed in the composite resin primer, which makes both the hardness and flexibility insufficient for high wear-resistant occasions. The ideal superhydrophobic primer coating should have: i) enough roughness; ii) good adhesion to both the substrate and topcoat;It is an important tendency to develop a durable superwetting coating for potential applications. However, its application, integration and evaluation mechanism in specific application environments are still inadequate toward practical applications. Herein, a universal approach to fabricate ultra-stable and multifunctional superhydrophobic composite coating with superoleophobicity or superoleophilicity using cross-linked composite resin as reinforcement is reported. The nano-porous structure with extremely low surface energy is endowed with excellent mechanical stability, to gre...

“…Fluorocarbon materials are commonly employed to fabricate superhydrophobic coatings due to their inherent low surface energy [27][28][29], however, which are usually expensive and potentially damaged to the environments. Other materials with low surface energy are used to replace the fluorocarbons, such as polydimethylsiloxane [30,31], polyacrylate [32,33], polyethersulfone [34,35], polyvinylidene fluoride [36] and polybenzoxazine [37]. As a thermoplastic elastomer, styrene-butadiene-styrene (SBS) triblock copolymers have two-phase morphology of spherical polystyrene block domains within matrix of polybutadiene.…”

In this work, we developed a simple method to fabricate robust and anti-corrosive superhydrophobic coatings. The multiscale nano/microstructures were induced by styrene-butadiene-styrene and two kinds of nanoparticles of SiO 2 and TiO 2. The unique hierarchical structures contribute to the superhydrophobic coatings with a remarkable water contact angle of 154.4° and contact angle hysteresis of 2.1°. In particular, the superhydrophobic coatings exhibited excellent thermal stability, mechanical stability and self-cleaning property. The synergistic effect of SiO 2 nanoparticles and TiO 2 nanoparticles could improve corrosion resistance of the superhydrophobic coatings. The superhydrophobic coatings retained their original superhydrophobicity when directly soaked in 3.5 wt.% NaCl solution for 3 days. The electrochemical experiments show that the superhydrophobic coatings can significantly improve the corrosion resistance of aluminum plate. Furthermore, the superhydrophobic coatings were applied to oil/water separation. The superhydrophobic coatings give a promising prospect for practical applications in a broad range of fields based on their large-scale and low-cost fabrication method.

Extreme wettability materials applied for oil/water separation have become a research focus in modern society, owing to the large amounts of oil-containing industrial wastewater emissions and the frequent occurrence of oil spills. However, most of the methods to fabricate the extreme wettability materials involve toxic chemical reagents, complex chemical reaction processes, and dangerous operation processes. A new acid, alkali, and organic reagent-free cement-coated mesh was presented for the sustained separation of oil and water from oil/water mixtures. The meshes were fabricated by dipping porous Cu meshes in the cement paste. The micro/nanostructures and hydroxyl groups of the cement enable the meshes to be superhydrophilic in air and superoleophobic under water. The separation efficiencies for oils with a wide range of kinematic viscosities (0.42-74.4 cSt at 40 °C) were all above 94%. The superhydrophilic cement-coated meshes could separate the oil/water mixture containing hot water, salt, and alkali for at least 30 cycles. The superoleophobicity of the cement-coated meshes was intact under seawater for at least 120 hours, showing good durability and stability. This green fabrication method is easy, cost-effective and environment-friendly.
