Coacervates have been studied for a long time for their unusual properties: they are dense networks of charged polymers that are soluble in water. Instead of flocculating when exposed to high salt concentrations, they dissolve. They are fully permeable to water, yet they are capable of strongly binding heavy metals or large (bio-)molecules , making them useful for wastewater purification, coatings, and as drug carriers. By modifying them to form micelles, the micelle cores become small coacervate networks; Complex Coacervate Core Micelles (C3Ms). Unlike gels, they are dispersed into solution easily. The structure of C3Ms is quite well known, but exchange kinetics of the polymers between micelles is nearly unknown. Understanding these kinetics by direct observation with SANS is important to assess the stability of these micelles for their applications in non-ideal, real-life environments.
