The Modeling and Study of Depletion Interaction at mixture of C<sub>12</sub>E<sub>5</sub> Microemulsion with Polyethylene Glycol Polymer

Abstract

ABSTRACThe photon correlation spectroscopy and small-angle X-ray scattering is used for study the mixture of C 12 E 5 microemulsion with PEG in order to determine structure and dynamic of the system. Photon correlation spectroscopy experiment showed an exponential relaxation for pure C 12 E 5 microemulsion that come from Brownian motion of oil nano-droplets in water. The shape of the relaxation changed with increasing of PEG concentration in the C 12 E 5 microemulsion, (relaxation becomes non-exponential with the increase of PEG), which demonstrates an increase of cooperatively in the C 12 E 5 microemulsion. The SAXS experiment was used to study the structure of the system, and a model consists of a mixture of core-shell spheres with an Asakura-Oosawa interaction was applied to analyze data.

The Effect of Mixture of AOT Microemulsion with PEG-PPG-PEG Tri-Block Polymer on Surface

“…A lot of optical property of polymer was studied before, [4][5][6][7].The optical property of polymer depends to the polymer formation on the surface and the formation of polymer depends to the interaction of polymer with surface and between the polymer chains, [8,9]. So, one of interesting topic is to study the polymer composition and topography on surface.…”
