Superhydrophobic aluminum alloy surfaces by a novel one-step process [PDF]

, 2010
A simple one-step process has been developed to render aluminum alloy surfaces superhydrophobic by immersing the aluminum alloy substrates in a solution containing NaOH and fluoroalkyl-silane (FAS-17) molecules.

Multiscale Superhydrophobic Zeolitic Imidazolate Framework Coating for Static and Dynamic Anti‐Icing Purposes

Advanced Materials Interfaces, 2023
Ice formation is a major challenge for engineering systems. Superhydrophobic surfaces constitute an effective approach to address this challenge. However, in addition to complex preparation methods, surface texture‐ and chemistry‐related shortcomings ...

Super-Hydrophobic Multi-Walled Carbon Nanotube Coatings for Stainless Steel

, 2015
We have taken advantage of the native surface roughness and the iron content of AISI 316 stainless steel to direct grow multi-walled carbon nanotube (MWCNT) random networks by chemical vapor deposition (CVD) at low-temperature ($< 1000^{\circ}$C ...

Statistical Mechanics of Electrowetting

Entropy
We derive the ab initio equilibrium statistical mechanics of the gas–liquid–solid contact angle on planar periodic, monodisperse, textured surfaces subject to electrowetting. To that end, we extend an earlier theory that predicts the advance or recession

Corrosion and wettability of PEO coatings on magnesium by addition of potassium stearate

Journal of Magnesium and Alloys, 2017
Hydrophobic PEO coatings were fabricated in an electrolyte containing potassium stearate. The wetting behaviour of coated samples was studied using dynamic and static contact angle.

Wetting hysteresis induced by nanodefects [PDF]

, 2015
Wetting of actual surfaces involves diverse hysteretic phenomena stemming from ever-present imperfections. Here, we clarify the origin of wetting hysteresis for a liquid front advancing or receding across an isolated defect of nanometric size.

Microstructured superhydrorepellent surfaces: Effect of drop pressure on fakir-state stability and apparent contact angles

, 2009
In this paper we present a generalized Cassi-Baxter equation to take into account the effect of drop pressure on the apparent contact angle theta_{app}.
