emulsions

Emulsions are found in numerous products and industrial processes. The performance of these products and processes is tied tightly to their colloidal stability so that the interfacial structure plays a critical role. In many processes, the fluid-fluid interface is stabilized by nanosized particles or proteins that can act as a physical shell preventing drop coalescence. For charged particles, the stabilization can also be a result of electrostatic interactions. Despite the industrial relevance of these systems, the physical interactions that control their phase behavior are not very well known due to the nanoscale dimensions. In this project, we utilize a combination of scattering techniques (SAXS, SANS and light scattering) to probe the organization of nanoparticles at the emulsion interface and correlate this to their interfacial behavior.
