Free-disperse systems electrostatic component

Only the dispersion and electrostatic components of disjoining pressure have been used to compare with the experimental data. It looks like these two components are not enough to adequately describe the behavior of thin liquid films and the transition region in the system under consideration. The influence of both the stractural (caused by the orientation of water dipoles in the vicinity of free film surfaces) and steric (caused by the direct interaction of the head of the surfactant molecules on the film surfaces) components cannot be ignored. The theory of these components of disjoining pressure is to be developed. [Pg.143]

The electrostatic components of disjoining pressure and free energy of interaction in the film, given by eqs. (VII.21) and (VII.22), are positive, i.e. represent repulsion. These quantities may be compared with corresponding molecular components that are negative and describe attraction. This allows one to analyze according to the DLVO theory the stability of thin films, and consequently of disperse systems stabilized by adsorption layers. Carrying out summation of eqs. (VII.21) and (VII.22) with expressions (VII.9) and (VII. 10) one obtains ... [Pg.548]
