Dynamics of viscous amphiphilic films supported by elastic solid substrates

open access: yes, 1997
The dynamics of amphiphilic films deposited on a solid surface is analyzed for the case when shear oscillations of the solid surface are excited. The two cases of surface- and bulk shear waves are studied with film exposed to gas or to a liquid.
