The bizarre rneological properties of microemulsion with anionic surfactant |

| Abstract: | Optically transparent oil-water dispersions (microemulsions) formed spontaneously upon mixing hexadecane, hexanol, K oleate, and water in specific proportions. Microemulsion viscosities were measured for several oil-water ratios. The striking optical and viscosity changes observed at specific water/oil ratios are consistent with a phase inversion mechanism of the type water spheres ?water cylinders ?water lamellae ?continuous water phase. In the lamellar region, the dispersion exhibits neg. thixotropic and shear thickening properties. The abnormal rheol. properties exhibited by dispersions with water/oil ratio = 1 are explained in terms of ion-dipole association between oleate and hexanol mols. on adjacent droplets. This phenomenon was studied as a function of pH, water ratio, and added salt (KCl, BaCl2, LaCl3) nature and concentration |
