Electrowetting-induced dewetting transitions on superhydrophobic surfaces.
نویسندگان
چکیده
We develop and demonstrate the use of electrowetting to achieve the dewetting (Wenzel-to-Cassie transition) of superhydrophobic surfaces. We effect this transition by means of an opposing flat plate and a three-electrode system; the liquid droplet is completely pulled out of its wetted Wenzel state upon the application of a suitable voltage. We also experimentally quantify the dissipative forces preventing the dewetting transition. The energy associated with these nonconservative forces is comparable to the interfacial energies.

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 کاملReversible wetting-dewetting transitions on electrically tunable superhydrophobic nanostructured surfaces.
In this work, electrically controlled fully reversible wetting-dewetting transitions on superhydrophobic nanostructured surfaces have been demonstrated. Droplet behavior can be reversibly switched between the superhydrophobic Cassie-Baxter state and the hydrophilic Wenzel state by the application of electrical voltage and current. The nature of the reversibility mechanism was studied both exper...
متن کاملWetting and dewetting transitions on hierarchical superhydrophobic surfaces.
Many natural superhydrophobic structures have hierarchical two-tier roughness which is empirically known to promote robust superhydrophobicity. We report the wetting and dewetting properties of two-tier roughness as a function of the wettability of the working fluid, where the surface tension of water/ethanol drops is tuned by the mixing ratio, and compare the results to one-tier roughness. Whe...
متن کاملElectrowetting on Superhydrophobic Surfaces: Present Status and Prospects
Electrowetting devices with an initial superhydrophobic water contact angle (>150◦) have now been demonstrated on a variety of structured substrates. These substrates are more complex than a conventional superhydrophobic surface since electrowetting requires an electrical conductor that is coated with a highperformance dielectric and a hydrophobic fluoropolymer. Substrate structures that have b...
متن کاملDroplet Shapes on Superhydrophobic Surfaces under Electrowetting Actuation
Droplet behavior on structured surfaces has recently generated a lot of interest due to its application to selfcleaning surfaces and in microfluidic devices. In this paper, the droplet shape and the droplet state on superhydrophobic surfaces are predicted using the Volume of Fluid (VOF) approach. Various structured surfaces are considered and the apparent contact angles are extracted from the p...
