Association of surfactants and polymers studied by luminescence techniques
Descrição
Light emission spectroscopy has unique possibilities for the study of central issues of surfactants and associating polymers. With the help of luminescent probes, information may be obtained on matters such as molecular association, microstructure, and molecular dynamics; this constitutes an important contribution to the understanding and control of macroscopic properties, as well as biological function and technical applications. Important aspects of these systems considered in this review are: formation of micelles and hydrophobic microdomains; aggregation numbers of surfactants; shape of molecular aggregates; size of droplets in water or in oil in microemulsions; formation and stability of vesicles; intra- vs. intermolecular association in polymers; conformational changes in polymers; polymer-surfactant association; surfactant organization in adsorbed layers; kinetic aspects regarding the formation and disintegration of self-assembly structures; residence times of molecules in microdomains and migration of active molecules. http://www.sciencedirect.com/science/article/B6V5F-423HJVT-2/1/20eaa5a1608d64c5cc9c31135f1b54df
