“…This mirror-like interface is ascribed to an air layer trapped between water and the rough microstructures of the as-prepared mesh, demonstrating that the mesh is not wetted by water (Figure 4b). 40,41 The phenomenon of mirror effect agrees well with the Cassie wetting state. If a bubble is released below the mesh and touches the mesh in water, the air in the bubble is able to enter into the trapped air layer under the driving force of pressure (Figure 4d).…”

Reversible switch between underwater superaerophilicity and superaerophobicity on the superhydrophobic nanowire-haired mesh for controlling underwater bubble wettability Controlling the underwater bubble wettability on a solid surface is of great research significance. In this letter, a simple method to achieve reversible switch between underwater superaerophilicity and underwater superaerophobicity on a superhydrophobic nanowire-haired mesh by alternately vacuumizing treatment in water and drying in air is reported. Such reversible switch endows the as-prepared mesh with many functional applications in controlling bubble's behavior on a solid substrate. The underwater superaerophilic mesh is able to absorb/capture bubbles in water, while the superaerophobic mesh has great anti-bubble ability. The reversible switch between underwater superaerophilicity and superaerophobicity can selectively allow bubbles to go through the resultant mesh; that is, bubbles can pass through the underwater superaerophilic mesh while are fully intercepted by the underwater superaerophobic mesh in a water medium. We believe these meshes will have important applications in removing or capturing underwater bubbles/gas. © 2018 Author (s)

“…The water repellency was further improved by the addition of fluoroalkylsilane. Nowadays, some researches [24,25] used silica nanoparticles to create surface rough micro/nanostructures with subsequent modification of hydrophobic materials (e.g., fluoroalkylsilane, long-chain alkylsilane) to prepare superhydrophobic surfaces by multiple-step procedure [26,27]. Huang et al [28] fabricated superhydrophobic transparent surfaces by a sol-gel method with silica-based coating in ethanol and subsequent coating of a low surface energy material 1H,1H,2H,2H-perfluorooctyltrichlorosilane.…”

The hexadecyltrimethoxysilane(HDTMS)-modified silica (H-SiO 2 ) nanocomposite hydrosol was prepared via water-based sol-gel reaction with methyltrimethoxysilane (MTMS) and HDTMS as precursors under alkaline condition in the presence of surfactant. The influences of base catalyst amount and surfactant concentration on the particle size and distribution of H-SiO 2 nanocomposite hydrosol were analyzed. The obtained H-SiO 2 nanocomposite was characterized by particle size analyzer, Fourier-transform infrared spectrometry (FTIR), thermal gravimetric (TG) and field emission scanning electron microscopy (FE-SEM), respectively. The H-SiO 2 nanocomposite hydrosol was applied to coat onto the cotton fabric sample via one-step process. The cooperative action of rough surface structure due to the silica nanoparticles and the low surface energy caused by long-chain alkylsilane in the H-SiO 2 nanocomposite coating provided the treated cotton fabric with excellent superhydrophobicity.

Preparation and corrosion resistance of iron plate with micro-nano-structure were investigated. A clean iron plate was etched with a mixture of FeCl 3 , H 2 O, hydrochloric acid, H 2 O 2 and H 3 PO 4 to form a super hydrophilic surface which was treated with fatty acid solution to form a micro-nano-structure surface on which the water contact angle was about 147°. The super hydrophilic surface was treated with 3-aminopropyltriethoxysilane solution and then fatty acid solution (test plate) to turn to a super hydrophobic surface and the water contact angle was greater than 150°. This test plate coated with alkyd vamish exhibited better corrosion resistance to H 2 SO 4 than blank iron plate.
