Introduction
Polyelectrolytes are polymers bearing dissociated ionic groups. Their unique
properties, dominated by strong long-range electrostatic interactions, have
been studied over the past few decades. Substantial theoretical and experimental efforts have been made, for example, to understand the origin of ‘slow’’ domains or ‘‘loose’’ clusters in semidilute solutions of highly
charged polyelectrolytes. This kind of attractive interaction between macroions is not consistent with the standard theory based on the overlap of the electrical double layers between charged flat surfaces. Charge-fluctuation forces between several polyions due to sharing of their counterions or attraction by expansion of the condensed layers between charged rods have been suggested to explain the appearance of these formations. Particular focus has also been placed on polyion interactions with counterions, since their condensation on the polyion surface is one of the most characteristic properties of the polyelectrolytes. The interaction of polyions with other charged or neutral species and, in particular, the adsorption of ionizable polymers at interfaces, is the second aspect of the physical chemistry of polyelectrolytes that has been extensively studied due both to the fundamental importance of this phenomenon and to its central role in numerous industrial processes.
