A Modified Contact Angle Measurement Process to Suppress Oil Drop Spreading and Improve Precision

Molecules, 2022
Static contact angle measurement is a widely applied method for wettability assessment. Despite its convenience, it suffers from errors induced by contact angle hysteresis, material heterogeneity, and other factors.

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 ...

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

Wetting and Contact-Angle Hysteresis [PDF]

Nature, 1950
THE study of contact angles and contact-angle hysteresis in the region of low contact angles is not easy owing to difficulties of technique. The contact angle, θ, is given by where θ is the contact angle measured in the liquid and γSA, γSL and γLA are the surface free energies per

Geometric Interpretation of Surface Tension Equilibrium in Superhydrophobic Systems

Entropy, 2015
Surface tension and surface energy are closely related, although not identical concepts. Surface tension is a generalized force; unlike a conventional mechanical force, it is not applied to any particular body or point.
