Multifunctional superhydrophobic surfaces
Advances in Colloid and Interface Science, 2021Surface wetting has a significant influence on the performance and applications of the materials. The superhydrophobic surfaces have water repellency due to low surface energy chemistry and micro/nanostructure roughness. The amazing applications of superhydrophobic surfaces (SHSs) lead to increase attention to superhydrophobicity in recent decades. The

Superhydrophobicity is mainly remarkable for the special dynamical behaviours it generates: low adhesion, giant hydrodynamic slip, frictionless motion, rebounds after impacts. Here we discuss most of these properties. We first recall how contact angle hysteresis can be minimized in this state.

It is well known that the roughness of a hydrophobic solid enhances its hydrophobicity. The contact angle of water on such flat solids is typically of the order of 100 to 120 degrees, but reaches values as high as 160 to 175 degrees if they are rough or microtextured.

Metastable Underwater Superhydrophobicity
Physical Review Letters, 2010Superhydrophobicity is generally considered to be a thermodynamically stable wetting state. The stability of the plastron (the thin air film separating the substrate from the water in the superhydrophobic state) was studied in underwater experiments. The plastron exhibited a rapid decay after a well defined onset time, which was found to be dependent ...

Superhydrophobic Graphene Foams
Small, 2012AbstractThe static and dynamic wetting properties of a 3D graphene foam network are reported. The foam is synthesized using template‐directed chemical vapor deposition and contains pores several hundred micrometers in dimension while the walls of the foam comprise few‐layer graphene sheets that are coated with Teflon.

Electrokinetics on superhydrophobic surfaces
Journal of Physics: Condensed Matter, 2012On a superhydrophobic surface a liquid is exposed to a large air-water interface. The reduced wall friction is expected to cause a higher electro-osmotic mobility. On the other hand, the low charge density of a superhydrophobic surface reduces the electro-osmotic mobility.

Superhydrophobicity from the Inside
Langmuir, 2017The nature of trapped air on submersed ultra-water-repellent interfaces has been investigated. These gaseous layers (plastrons) can last from hours to, in some examples such as the Salvinia molesta fern, months. The interface of submerged superhydrophobic surfaces with carefully controlled micropatterned surface roughness has been probed using ...

Superhydrophobic Fibrous Polymers
Polymer Reviews, 2013Superhydrophobicity coming from the appropriate structuration, morphology, and low surface energy material, is a more and more demanded property in many fields. Especially superhydrophobic fibers are interesting because of their re-entrant structure and their potential applications in apparel.

Superhydrophobicity and Superhydrophilicity of Regular Nanopatterns [PDF]
Nano Letters, 2005 The hydrophilicity, hydrophobicity, and sliding behavior of water droplets on nanoasperities of controlled dimensions were investigated experimentally. We show that the "hemi-wicking" theory for hydrophilic SiO(2) samples successfully predicts the experimental advancing angles and that the same patterns, after silanization, become superhydrophobic in ...

Hydrophobic and Superhydrophobic Polyphosphazenes
Journal of Adhesion Science and Technology, 2009Polyphosphazenes are a class of hybrid organic–inorganic polymers that have good solubility in classical organic solvents and are thermo-oxidatively stable. Over the years, poly(dichlorophosphazene) has been used as a macromolecular intermediate to yield a number of polymers which can be hydrophobic or superhydrophobic.
