Contact-angle hysteresis induced by pulmonary surfactants
Journal of Applied Physiology, 1983Hydrophilic surfaces in the form of glass slides have been coated with monolayers of three of the major components of pulmonary surfactant, and the wettabilities of the resulting surfaces have been studied by applying a single drop of saline. As fluid was added and removed over successive cycles, there was much hysteresis between the contact angle ...

Contact angle hysteresis: surface morphology effects
Colloid and Polymer Science, 2012Irradiation of metallic surfaces using ultra- short pulse laser results in a dual-scale structure. While metallic surfaces are superhydrophilic immediately after laser irradiation, prolonged exposure to air renders sur- faces superhydrophobic due to surface reactions and deposition of carbonaceous materials onto the surface.

Contact Angle Hysteresis on Random Surfaces
Europhysics Letters (EPL), 1987Contact angle hysteresis on weakly heterogeneous surfaces is studied using an extension of Imry and Ma's analysis of the random field problem. Deformations of the liquid-vapor interface in response to the heterogeneity are characterized by a length Ld which increases as the magnitude of the heterogeneity decreases.

Thermodynamic aspects of contact angle hysteresis
Advances in Colloid and Interface Science, 1994Abstract Theoretical models regarding the thermodynamic aspects of contact angle hysteresis are reviewed. General thermodynamic considerations are briefly summarized in order to emphasize the local nature of the thermodynamic equilibrium condition regarding the contact angle.

Contact angle hysteresis: A molecular interpretation
Journal of Colloid and Interface Science, 1980Abstract “Intrinsic contact angle hysteresis” is defined as hysteresis that cannot be ascribed to roughness, heterogeneity, or penetrability of the solid surface. It can be explained if we postulate that the layer of liquid immediately adjacent to the solid surface has an ordered structure similar to that of a liquid monocrystal.
