Mechanical response of adsorption layers
Interfacial viscoelasticity isnot a single material constant.
Interfacial rheology describes the mechanical response of an adsorption layer when a fluid interface is deformed. The response can contain both elastic and viscous contributions and depends on interfacial composition, age, deformation amplitude and frequency.
