“…Thus, the force balance used to obtain Young-Dupré equation at a line is replaced by force balance over a region and allows many details of a contact line to emerge other than the contact angle itself. Investigators have included in the disjoining pressure the dispersion forces (2, 3), short-range repulsion (4), polar forces (5), gradient forces (6, 7), a combination of dispersion and electrostatic double-layer forces (8,9), the structural effects of micelles (10)(11)(12), and the randomness of dissolved polymers (13). Of course, many of these calculations are phenomenological, but have served well since the time they were originally conceived by Derjaguin and co-workers (16).…”

“…(This same phenomenon also occurs in the transition region between two bulk phases and is usually analyzed through the concept of surface tension.) Two different procedures have been utilized to account for the influence of the van der Waals interaction on the film dynamics: a disjoining pressure approach (3,4,20,21) and a body force procedure (2,8,11).…”

The stability of thin (< 100 nm) symmetrical and unsymmetrical membranes, assimilated with viscous liquids, to short and long wavelength perturbations is investigated. The asymmetry is due to the two different viscous phases surrounding the membrane and to the different interfacial tensions on the two faces of the membrane. The cell membrane is a case for which the present treatment is of significance. The dynamics of the membrane to perturbations is described by the Navier-Stokes equation modified with a body force which accounts for the fact that the range of the interaction forces is larger than the thickness of the film. The body force is computed assuming pair-wise additivity and accounting for the deformation of the interface produced by the perturbation. General dispersion equations are derived, and these equations describe the squeezing and stretching modes of perturbations. The growth coefficient is expressed as a function of the wavelength for various ratios of the viscosities of the two surrounding phases and various values of the two interfacial tensions. In the limiting cases of interfacial tension ratio equal to unity and wavelength large compared to the thickness of the film results of the previous investigators are obtained. For the symmetrical case expressions are derived for the critical and dominant wavelength of the squeezing and stretching modes. An application of the results to a cell membrane shows that the growth of the instability is dominated in this case by the stretching mode since the time scale of growth of the perturbations is four orders of magnitude less than that in the squeezing mode. For unsymmetrical systems the effect of differences between the interfacial tensions on the two faces on the ratio of the amplitudes of perturbations on the two faces is investigated. The results show in what manner differences in interfacial tension convey amplified or damped messages across the membrane.
