This chapter discusses methods for converting the many body problem in interacting polymer fluids to a statistical field theory. Auxiliary field transforms are introduced, that decouple interactions among polymer species and reduce the problem to that of individual polymers interacting with one or more fluctuating fields — the subject of Chapter 3. Examples of models for a variety of systems are enumerated, including polymer solutions, blends, block and graft copolymers, polyelectrolytes, liquid crystalline polymers, and polymer brushes.Less

This chapter describes transport in liquid membranes and aims at introducing the concepts of carrier-mediated transport and coupled transport. The topics of facilitated, competitive, co-transport, and counter-transport are covered making use of examples of practical interest. Although this chapter concentrates on relatively simple transport problems involving neutral solutes and heterogeneous complexation reactions, it provides a good introduction to the solution of reaction-diffusion problems. Some basic ideas of liquid¦liquid interfacial electrochemistry are also introduced.Less

This chapter aims to demonstrate the application of dielectric spectroscopy to aqueous polyelectrolyte solutions and to mixed polyelectrolyte–colloid solutions, showing what kind of information, at a molecular level, can be obtained by this technique on the peculiar behavior of these systems. Particular attention is devoted to the study of the interaction of polyelectrolytes with oppositely charged colloidal particles, and particularly lipid vesicles (liposomes) due to the increasing importance of these systems for different applications, especially in medical biotechnologies. After a brief description of polyelectrolytes and liposomes, we describe how dielectric spectroscopy can be used in the study of the physical properties of polyelectrolytes in aqueous solutions. To show the potential of the technique, we briefly review two examples of the use of dielectric spectroscopy in the study of mesoscopic polyelectrolyte–liposome aggregates.Less
