Fabrication of superhydrophobic polyurethane/MoS2 nanocomposite coatings with wear-resistance

Durable superhydrophobic/superoleophilic epoxy/attapulgite nanocomposite coatings for oil/water separation

“…Lin et al prepared superhydrophobic and superoleophobic fabrics coated with a hydrolysis product from fluorinated-decyl polyhedral oligomeric silsesquioxane and a fluorinated alkyl silane, which showed excellent durability to acid, UV light, machine wash, and abrasion [27]. In our previous work, we reported a wear-resistant superhydrophobic and oleophobic coating using polyurethane/molybdenum disulfide nanocomposites [28]. Based on these works, in this article, we successfully fabricated durable superhydrophobic/superoleophilic coatings for oil/water separation through spray-coating the suspension of epoxy resin and attapulgite on the stainless steel meshes.…”

Facile fabrication of wear-resistant multifunctional surfaces on titanium alloy substrate by one-step anodization and modification with silicon dioxide nanoparticles

“…mixed deionized water-glycerol solution at a voltage of 20 V for 60 min and obtained an irregularly arranged micro-to nanosurface after annealing. The above studies focused on the continuous optimization of the electrochemical technique in simplified procedures, the environmental friendliness of the reaction reagent, and the operability of the reaction condition, but few of them considered the mechanical stability of the surface [5,21,22]. However, multifunctional surfaces lacking a stable surface structure would have problems such as a short service life and requirement for frequent replacement, which would limit the application of these multifunctional surfaces in real environments.…”

Green preparation of a cellulose nanocrystals/polyvinyl alcohol composite superhydrophobic coating

“…Especially in the most spray methods, the paint is rst prepared using organic solvents and then sprayed onto the substrate surface. [15][16][17] The organic solvents evaporate into air and pollute the environment, especially when spraying is done indoors, where relatively conned spaces have poor ventilation. In preparation process of superhydrophobic coatings, ethanol, 18 tetrahydrofuran, 19 acetone, 20 toluene, 21 and so on were common organic solvents which were toxic or ammable and explosive substances.…”
