Resumen:
This review paper presents a procedure for measuring the mesoscopic
scales in micellar solutions embedded with giant cylindrical micelles
using the mean square displacement determined with a quasi-elastic
multiple light scattering method (diffusing wave spectroscopy) and
theory. The mesoscopic scales of interest are the micelles' total
contour length, persistence and entanglement lengths, and the mesh size
of the entangled micellar network. All of them depend on the
physicochemical parameters of the solutions and determine the
rheological behavior. We present an assessment of the whole procedure,
the scattering experiments performance, the recovery of optical
parameters, which includes dealing with the light absorption and its
treatment, and how to develop the micro-rheology for obtaining the
mesoscopic scales in these complex fluids.
