Investigation of Polyelectrolyte-Surfactant precipitates
Mixtures of oppositely charged surfactant and polyelectrolyte show rich aggregation behaviour that varies over a large size range. Some of these systems allow to control the rheological properties of water-based systems. Generally the macroscopic phase behaviour of these mixtures can be described by two monophasic regions in which clear, stable solutions are formed and a region in between where precipitation is observed. The precipitates usually form around charge equilibrium, while both an excess of surfactant or PE charges leads to the formation of stable solutions. Here, we want to investigate the bifasic region to understand the microstructural organization of precipitates.
