Contact angle hysteresis and lateral adhesion strength on random rough surfaces
The Physics of Fluids, 2022Based on the classical RJ model of contact angle hysteresis, a new dimensionless parameter ( q0/ q2) sensitive to roughness power spectrum is proposed to be linearly related to (1) contact angle hysteresis caused by roughness heterogeneity and (2 ...

A Hysteretic Model Considering Contact Angle Hysteresis for Fitting Soil‐Water Characteristic Curves
Water Resources Research, 2021The soil‐water characteristic curve (SWCC) plays an essential role in the analysis of the shear strength, deformation, hydraulic conductivity, and aqueous diffusion of unsaturated soils.

Contact Angle Hysteresis Explained
Langmuir, 2006A view of contact angle hysteresis from the perspectives of the three-phase contact line and of the kinetics of contact line motion is given. Arguments are made that advancing and receding are discrete events that have different activation energies. That hysteresis can be quantified as an activation energy by the changes in interfacial area is argued ...

Hysteresis during contact angles measurement
Journal of Colloid and Interface Science, 2010A theory, based on the presence of an adsorbed film in the vicinity of the triple contact line, provides a molecular interpretation of intrinsic hysteresis during the measurement of static contact angles. Static contact angles are measured by placing a sessile drop on top of a flat solid surface.

Thermodynamically consistent phase-field modelling of contact angle hysteresis
Journal of Fluid Mechanics, 2020In the phase-field description of moving contact line problems, the two-phase system can be described by free energies, and the constitutive relations can be derived based on the assumption of energy dissipation.

Dynamic contact angles and contact angle hysteresis
Journal of Colloid and Interface Science, 1977Abstract Contact angles have been measured as a function of the three-phase-boundary velocity. Large velocity effects observed with other techniques were not seen using the plate method. It is possible to relate the dependence of contact angles on velocity to surface heterogeneity.

Contact Angle Hysteresis of Microbead Suspensions
Langmuir, 2010Microbead suspensions are often used in microfluidic devices for transporting biomolecules. An experimental investigation on the wettability of microbead suspension is presented in this study. The variation in the surface tension and the equilibrium contact angle with the change in the volume fraction of the microbead is presented here.
