This monograph considers the main physicochemical aspects, such as preparation, structure, and properties, of foam and foam films; special emphasis is placed on foam stability. A major contribution represents the independent consideration of formation and stability of foam films in theoretical and experimental aspects. Data and information about foams, physicochemical characterization of surfactants, phospholipids and polymers is also presented.

From the Preface: “...In the present monograph, we have attempted to both explain and describe the processes running in the foams and their equilibrium properties on the basis of quantitative regularities of electrostatic, molecular, etc. interactions, physicochemical, hydrodynamic and other surface phenomena. However, considering the complex nature of foam properties, it has, understandably, proved impossible for a number of properties and processes, still awaiting quantitative explanation...”

Target Audience: Graduate and postgraduate students, scientists, researchers, and technologists dealing with thin liquid films, colloids, oil recovery, and bioengineered surfaces.
