Light Scattering Study of Mixture of Polyethylene Glycol with C_{12}E_{5} Microemulsion

ABSTRACT

The mixture of C_{12}E_{5} microemulsion 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 C_{12}E_{5} microemulsion that with increasing of PEG concentration in the C_{12}E_{5} microemulsion, relaxation becomes non-exponential, which demonstrates that increase of cooperativity. The study structure of the system with SAXS experiment, shown with increasing of PEG concentration, the size of the droplet doesn’t change but interaction between droplets increases that have agreement with light scattering data’s.

The mixture of C
