Light Scattering Study of Mixture of Polyethylene Glycol with C<sub>12</sub>E<sub>5</sub> 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.

Photon Correlation Spectroscopy and SAXS Study of Mixture of NaCl with AOT Microemulsion at X = 6.7

“…Our results show that the length scale of the droplet changes from 60 Å to 30 Å and shape of droplets changed from spherical to cylindrical by increasing the mass fraction. The study of the C 12 E 5 microemulsion at different droplet mass fraction shows a repulsive behavior that with increase of concentration of PEG on the C 12 E 5 microemulsion, system become attractive [19,20]. In the AOT microemulsion, the collective diffusion coefficient shows a negative slop at mass fraction and so shows a attractive interaction that with add NaCl the interaction stay attractive.…”

Polymer length scale on modification of a reverse microemulsion

“…[4] For instance, by reducing the colloid mass fraction, for a system with attractive interaction, the diffusion coefficient increases. [4] In general, microemulsions can be used to deliver drugs for patients via several ways; furthermore, the topical application of microemulsions has gained increasing attention. [6,7] Microemulsions have gained interest not only for the delivery of mixture component but also due to their preferential solubility in either water or oil phases.…”

“…[1][2][3][4][5] The interactions can be precisely controlled as many relevant parameters such as ion, [1,2] the shape of particles, [3] additive and concentration.
