Other natural surfactants occur in the digestive system, in the lungs, and even in such substances as crude oil. Man-made surfa

Adsorption at liquid interfaces,ised in Figure 2.1. Since the polar head group has a strong preference for remaining in the water and the hydrocarbon tail favours leaving the water, the simple picture that comes to mind for molecules accumulating at the surface of water is that of a monomolecular layer. In fact, this is the most c

Insoluble monolayers, seen how the accumulation of water soluble surfactant molecules at the air/water or oil/water interfaces results in the formation of well-ordered, usually monomolecular, layers. The concentration in water at which these interfaces become filled is a measure of surface activity of the amphiphile, th

General phase behaviour of surfactants,ly small that an aqueous solution behaves like an isotropic fluid. Only when micelles grow to cylinders with considerable asymmetry does the solution start to show features of structure on a macroscopic scale, for example, flow or electric birefringence. Even in these cases, the solution behaves lik

Dispersions of surfactant aggregates,Although they might be made to separate from the equilibrium monomer solution in a high-speed centrifuge, micelles do not normally sediment under gravity. Thermodynamically, a micellar solution can be treated as a single phase although, as seen in chapter 5, the phase-separation model is an entirely

Adsorption on solids,eous) phase in which the surfactant is dissolved has been considered. The only exception was in chapter 4 where Langmuir—Blodgett multilayers represent a type of interaction with a solid surface, albeit rather artificially forced upon the system. Our attention is now turned to systems where a solid
