Dewetting Transitions on Superhydrophobic Surfaces: When Are Wenzel Drops Reversible?
On superhydrophobic surfaces, drops in the Wenzel state can be switched to the suspended Cassie state in some cases but in other cases are irreversibly impaled in the surface roughness. To date, the question of when dewetting transitions are possible for Wenzel drops has not been resolved. Here, we show that pinned Wenzel drops being stretched out-of-plane cannot reduce their contact angle belo...
متن کاملThe rational nanostructuring of surfaces for extraordinary icephobicity
1. Thermodynamic Relations and Poisson Statistics The thermodynamically guided tailoring of surface morphologies aims at depressing the heterogeneous ice nucleation rate by unfavorable thermodynamic conditions stemming from the surface/droplet interaction. The theoretical framework for this surface morphology tailoring can be established by invoking the use of the classical heterogeneous nuclea...
متن کاملSuperhydrophobic surfaces reduce drag
Rare and common The hot grains of tektite and obsidian that show up in HD 172555’s IR spectrum are small enough that the star’s radiation pressure would drive them away from their current 6-AU orbit within 0.1 million years. The SiO molecules would likely condense and reform minerals on the same time scale. Given that rocky planets take 100 My to form, catching a giant impact in HD172555, despi...
متن کاملMechanically durable superhydrophobic surfaces.
Development of durable non-wetting surfaces is hindered by the fragility of the microscopic roughness features that are necessary for superhydrophobicity. Mechanical wear on superhydrophobic surfaces usually shows as increased sticking of water, leading to loss of non-wettability. Increased wear resistance has been demonstrated by exploiting hierarchical roughness where nanoscale roughness is p...
متن کاملHierarchical roughness optimization for biomimetic superhydrophobic surfaces.
Superhydrophobic surfaces should have high contact angles (CA) with water and low contact angle hysteresis (CAH). High CA may be achieved by increasing surface roughness, while in order to have low CAH, superhydrophobic surfaces should be able to form a stable composite interface with air pockets between solid and liquid. Capillary waves, nanodroplets condensation, hydrophilic spots due to chem...
