Covers the rheology of surfactant solutions, from theoretical models to practical industrial applications of these systems. Discusses a wide range of surfactant structures, including entangled worm-like micelles, spontaneous vesicle systems with yield stresses, lamellar, hexagonal, and cubic liquid crystalline phases, and polymer-micelle complexes. Includes coverage of cryo-TEM, SANS, SAXS, light scattering, time-resolved fluorescence quenching, NMR, rheo-optical techniques, and optical probe diffusion methods used to study the link between structure and rheology.
