Abstract

Recently, a novel concept has been proposed to interpret the nonequilibrium character of oppositely charged polyelectrolyte/ surfactant mixtures. According to this approach, at low surfactant-to-polyelectrolyte ratios the system is a thermodynamically stable solution. In a given composition range colloidal dispersions of the polyelectrolyte/surfactant nanoparticles are formed. In the presence of surfactant excess, the dispersions can be stabilised via the adsorption of the surfactant ions on the surface of the hydrophobic polyelectrolyte/surfactant nanoparticles. In the presence of polyelectrolyte excess, charge stabilised polyelectrolyte/surfactant dispersions might also be prepared if the charge of the macromolecules is large enough. These latter colloidal dispersions are stabilised by the uncompensated charges of the polyelectrolyte. The colloidal dispersion concept provides several options to control the formation of self-assemblies and the kinetic stability of the mixtures. In this paper, the effect of solution preparation protocols and different additives (including non-ionic polymers or surfactants) on the mentioned properties of oppositely charged macromolecule/surfactant systems is discussed.
