In this thesis, the dynamic light scattering (DLS) technique is applied to, and further developed for, the determination of the translational diffusivity for various heterogeneous systems. The investigated systems consist of technical polyol-based microemulsions and particulate systems in free media, as well as under confinement. While these microemulsions are of interest for the production of high-performance polyurethane insulation foam material using the POSME process, knowledge of the diffusion processes within particulate systems is necessary for the tailored design of particulate products such as columns for size-selected chromatography. Here, the translational diffusivity can be used to determine the size of droplets and particles in heterogeneous systems via the Stokes Einstein relation.<\/p>","protected":false},"excerpt":{"rendered":"
In dieser Arbeit wird die Methode der dynamischen Lichtstreuung (DLS) zur Bestimmung des translatorischen Diffusionskoeffizienten verschiedener heterogener Systeme angewendet und weiterentwickelt.
