A mathematical model is formulated and solved numerically describing the local thinning of liquid films between a solid/ liquid interface and a fluid/liquid interface with a variable surface concentration of an insoluble surfactant. Reynolds lubrication approximation is used. The initial excess surf

Film formation of three different latices was studied using atomic force microscopy. The latices were made from a mixture of butyl acrylate, styrene, and acrylic acid using either a polymerizable or an unreactive anionic surfactant as an emulsifier. Sodium 11-crotonoyloxyundecan-1-ylsulfate and sodi
The deformation, drainage, and rupture of an axisymmetrical film between colliding drops in the presence of insoluble surfactants under the influence of van der Waals forces is studied numerically at small capillary and Reynolds numbers and small surfactant concentrations. Constant-force collisions
