A non-aqueous electrodeposition process for fabrication of superhydrophobic surface with hierarchical micro/nano structure

Facile preparation of superhydrophobic and superoleophilic sponge for fast removal of oils from water surface

“…25,26 Obviously, the addition of NPs to the surface of PU/PTFE sponge increases the scrollability and hydrophobic feature of water droplets. In the case of PU/PTFE/A-SiO 2 /SiO 2 sample, the surface with micro-/nanostructure has a roughness enough 27,28 to trap air. When a water droplet is suspended on the rough structure, the air is trapped between the rough structures on a surface underneath the droplet, which is known as the Cassie state.…”

Insights into the superhydrophobicity of metallic surfaces prepared by electrodeposition involving spontaneous adsorption of airborne hydrocarbons

“…On the basis of this principle, a number of strategies have been developed to fabricate artificial superhydrophobic surfaces through controlling both of surface chemical composition and surface morphological structures. For example, superhydrophobic cotton textiles by solution immersion of polymethylsilsesquioxane [14], superhydrophobic coatings of organic/inorganic composites by sol-gel processes [15], superhydrophobic rose-like mordenire zeolites by hydrothermal synthesis and surface modification with octyltrimethoxysilane [16], superhydrophobic polystyrene films by phase separation [17], superhydrophobic silica-spherecoated substrates by fluorination treatment and layer-by-layer deposition of poly(diallyldimethylammonium chloride)/sodium silicate multilayer films [18], superhydrophobic substrates with dual-sized raspberry-like polystyrene/silica particles by colloidal self-assembly and surface modification with dodecyltrichlorosilane [19], superhydrophobic metal surfaces by electrodeposition [20,21] or electrooxidation [22] deposition [23], superhydrophobic aluminum alloy substrates by chemical etching in the presence of lauric acid [24], and so on [25,26].…”

The fabrication of superhydrophobic glass fiber-reinforced plastic surfaces with tunable adhesion based on hydrophobic silica nanoparticle aggregates

“…Superhydrophobic surfaces have many potential industrial applications, such as the surface self-cleaning [6], oil/water separation [7], efficient microfluidic devices [8], anticorrosive coatings [9], and so on. Superhydrophobic surfaces can be fabricated by combining rough surface morphology and low surface energy coatings, such as lithography techniques [10,11], templating process [12,13], layer-by-layer assembly [14][15][16], sol-gel technique [17,18], deposition technique [19][20][21], and spray coating [22][23][24][25]. It is reported that hierarchical surface roughness (i.e., both micrometer-and nanometer-sized roughness) is appropriate to show superhydrophobicity [23,26].…”
