A novel method to fabricate superhydrophobic surfaces based on well-defined mulberry-like particles and self-assembly of polydimethylsiloxane

Facile fabrication of superhydrophobic polysiloxane/magnetite nanocomposite coatings with electromagnetic shielding property

“…nanoparticle content, and also further confirms that ''one-pot coating'' method is feasible for acquiring the superhydrophobic coatings. The above percolation threshold for superhydrophobicity is close to that reported for polysiloxane/CaCO 3 /SiO 2 (40%) 27 and PS/nano-PFOA-TiO 2 (50%) 29 coatings, however, much higher than that of fluorinated polysiloxane/nano-TiO 2 coatings (25%) 33 in which the low percolation threshold may be due to the high porosity of TiO 2 nanoparticles aggregates.…”

“…For example, Yang et al prepared superhydrophobic coating by modification of micro-CaCO 3 /nano-SiO 2 composite particles with hexamethyldisilazane and further blending with a mixed polysiloxane binder that was composed of polydimethylsiloxane (PDMS), vinyltriethoxysilane, and c-aminopropyltriethoxysilane. 27 Cao et al prepared anti-icing superhydrophobic coatings from organosilane-modified nano-(or micro-)SiO 2 particles, acrylic polymer and silicone resin (Dow Corning 840). 28 Xu et al 29 combined perfluorooctanoic acid (PFOA)-modified TiO 2 nanoparticles with polystyrene (PS) while Harton et al 30 blended PDMS-modified SiO 2 with PS to get the superhydrophobic coatings.…”

“…[27][28][29][30] Namely, organic (or organic-inorganic hybrid) binder was blended with micro/nanoparticles and solvents, and then cast on substrates. After drying, superhydrophobic surface was readily achieved through the self-organization of the coating components.…”

Mechano-Chemical Preparation and Application of Mulberry-Like CaCo3/SiO2Composite Particles in Superhydrophobic Films

“…In this contribution, we present a simple, robust, and effective procedure to fabricate superhydrophobic surfaces with excellent film property by employing room temperature vulcanized (RTV) silicone rubber and mulberry-like composite particles based on the our early research (18). Because SiO 2 and CaCO 3 particles are reinforced fillers and semireinforced fillers of RTV silicone rubber, mulberry-like composite particles were prepared by adhering silicon dioxide nano-particles to microcalcium carbonate microparticles by vigorous stirring to prevent the agglomeration of the former.…”

Metal oxide thin films and nanostructures for self-cleaning applications: current status and future prospects

“…Surface topography plays a major role in the hydrophobic behavior of the surfaces. Techniques such as lithography, etching are effective to fabricate surfaces with different topology such as square pillars, parallel grooves [82][83][84][85][86][87][88][89][90][91][92]. Typical examples of polymer base superhydrophobic surfaces are shown in Figure 10.…”
