Abstract

Brownian motion is a subject of renewed interest since the development of photon correlation spectroscopy (PCS) in the last decade. The dynamic properties of microemulsions and colloidal systems are studied by measuring the relaxation of concentration fluctuations. The mixture of C₁₂E₅nanoemulsion with PEG have been studied by small-angle X-ray scattering and dynamic light scattering in order to determine structure and dynamic of the system. Light scattering experiment shown an exponential relaxation for pure C₁₂E₅ nanoemulsion that the shape of the relaxation change with increasing of polymer concentration in the C₁₂E₅ nanoemulsion, that relaxation becomes non-exponential, which demonstrates increase of cooperatively in the C₁₂E₅ nanoemulsion.
