Dynamics of Oil Exchange in PIC Nanoemulsion - Dependence on the Systems Composition

Abstract: The dynamics of oil exchange in oil-in-water (O/W) nanoemulsions produced spontaneously by the phase inverse concentration (PIC) method is only little known so far. In this experiment we will study this exchange dynamics by means of the stopped-flow method and mixing two otherwise identical PIC nanoemulsions that contain deuterated or hydrogenated oil. SANS is uniquely able to discern this exchange and we will study how the exchange kinetics depends on the composition of the surfactant monolayer (effect of electrostatic and steric stabilisation). The experiments will be done in a systematic fashion and by varying the chain length of the alkane we will be able to distinguish Ostwald ripening from coalescence. In summary we will be able to derive systematic correlations between the molecular compositon of the nanoemulsions and how that affects their internal exchange dynamics.
