Polyelectrolyte Microemulsion Complexes (PEMECs) with Structures Tunable by pH
By mixing polyelectrolytes and oppositely charged colloids one can control structure and rheology of the system. In many applications, micelles are used as carriers for drug molecules, pollutants, reactants and similar substances that otherwise couldn't be dispersed in the solvent. It is therefore of great importance to investigate the behavior of 'loaded carriers' as it can be different to that of normal (empty) micelles. Oil-in-water microemulsion droplets with oppositely charged polyelectrolytes can be studied in detail by SANS measurements, because of the good contrast conditions of neutrons and having appropriate size range. As both components, microemulsion and polyelectrolyte, have pH dependent charge conditions, we will study the complex formation as a function of pH. This shall open highly interesting insights into pH-triggered complexation and droplet release as it is important for controlled uptake, delivery and release of the carriers.
