Mechanically robust, chemically inert superhydrophobic charcoal surfaces

Abstract

We report a fast and cost-effective strategy towards the preparation of superhydrophobic composites where a double-sided adhesive tape is paved with charcoal particles. The composites are mechanically robust, and resistant to strong chemical agents.

A facile preparation of superhydrophobic L-CNC-coated meshes for oil–water separation

“…To better observe the status of water droplets, a piece of red paper was placed under the tested stainless steel meshes. It is well-known that the surface of the untreated mesh is intrinsically hydrophobic 33 and its WCA is 115.6 (as shown in Fig. 3a).…”

“…26 Also, hydroxyl acrylic resin could play a stabilizing role between hydrophobic modied SiO 2 and substrates. 27 Besides, PVA, 28,29 PDMS, 30,31 double-sided tape, 32 and PVDF 33 were involved in the enhancements of superhydrophobic surfaces.…”

Bio-inspired modification of silicon carbide foams for oil/water separation and rapid power-free absorption towards highly viscous oils

“…In principle, the ideal candidates for oil/water separation should be both hydrophobic and oleophilic, which can be achieved by a certain roughness (classical micro-nano hierarchical structure) with low surface energy materials [5,34]. But, it is not easy to achieve surface modification on SCFs because of the chemical inert of ceramic foams.…”

Low‐Cost and Scaled‐Up Production of Fluorine‐Free, Substrate‐Independent, Large‐Area Superhydrophobic Coatings Based on Hydroxyapatite Nanowire Bundles

“…Xie et al prepared the fluorine-free and mechanically robust superhydrophobic coating on glass by using charcoal particles. [26] Metal-organic frameworks( MOFs), a class of coordination compounds assembled by inorganic metal-containing nodes and organic linkers, [27] are another ideal alternative for fluorine-free superhydrophobic coatings. [28,29] Recently,s ilane and polymers were used to achieve high hydrophobicity.F or instance, Vüllers et al constructed nanohairs on polycarbonatef ilm by hot pulling.…”
