Dynamics and stability of thin films; Intermolecular forces


Wetting properties of a liquid comprise static and dynamic aspects. In the static case, the contact angle, spreading coefficient, and effective interface potentials are relevant. For dynamics, properties like the wetting or dewetting velocity, influenced by viscosity and viscoelasticity as well as by the hydrodynamic boundary conditions between the liquid and its confining media are important.


Equilibrium and dynamical wetting properties of liquid systems with nanoscopic dimensions on solid substrates are largely determined by the intermolecular interactions [1, 2] between all of a system’s constituent parts. Thus, the control of wetting properties relies on a thorough understanding of the microscopic mechanisms at the root. These interactions can be grouped as short ranged and long ranged. Observed macroscopic or collective phenomena result from a balance between these interactions at disparate len ...
