Outline of Final Research Achievements

In this study, we aimed to determine ways to control the physical properties of particles adsorbed at deformable interfaces, i.e. systems comparable to emulsions stabilized by particles. In particular, we investigated how the physical properties of the particles (size, hydrophobicity and charge) and the packing of the particles (packing density and mobility in the film) at a deformable interface such as an air/water interface affect the physical properties of the interface. We determined that the physical properties of the interface could be changed and controlled via the size and hydrophobicity of the particles, the particle packing density, and by the addition of another material (e.g., polymer or cross-linker) to the interface. We envision that the results obtained from our study will help improve the particle stabilized emulsions used in biotechnological and nano-technological applications.
