Influence of nanosized silica particles on the microstructure lamellar phase of AOT/Isooctane/ Water ternary system

ABSTRACT

Lamellar phase samples of AOT/isooctane/water ternary system were prepared. The microstructure of the lamellar phase containing nanosized silica particles was examined by optical polarized microscope [OPM] and Small Angle X-ray scattering [SAXS]. Both were used to investigate the phases changing for different silica particle concentrations. The interaction between dopled particle and bilayer of lamellar phase were analyzed and the change of silica concentration shows the defection of the bilayer structure of lamellar phase. The effect of silica concentration was profound in the images of lamellar phase and the phase changed from birefringent to isotropic with increases of concentration
