Pressure-indeced structural reorganization of polyelectrolyte-surfactant complexes
Within the proposed experiment, we aim to further investigate the response of polysaccharide/surfactant complexes towards applied hydrostatic pressure. Previous experiments performed on mixtures of the biopolycation chitosan and oppositely charged ethoxylated fatty acids revealed strong structural transition upon application of hydrostatic pressure. However, the structural changes observed in SANS experiments are in contrast with the predictions based on thermodynamic predictions from molar volumes. Herein, we propose to perform a further set of experiments which will allow us to understand which are the driving forces governing the pressure responsiveness of these systems.
