Droplet microemulsions confined to cylindrical nanochannels
The structural arrangement of colloids in confinement is a generally important topic that will be addressed here by employing rather monodisperse microemulsion droplets in well defined silica pores (SBA-15). In these experiments the size and surface charge of the microemulsion droplets will be varied systematically, as well as the pore size in order to achieve comprehensive insights into how these parameters affect the incorporation of microemulsion droplets into such pores. These experiments are both of fundamentally high interest, as these are very well defined model systems, but also relevant as the solubilisation of oil in the presence of pores is of central importance for processes like tertiary oil recovery or soil decontamination. SANS is uniquely qualified for this study as by contrast matching of the silica pores one can solely focus on the structural arrangement of the microemulsion droplets. From the analysis of the scattering patterns we will gain comprehensive insights into how this confinement affects the structure and arrangement of the soft microemulsion droplets.
