| Abstract: | We performed small angle neutron scattering (SANS) experiments in ternary microemulsion systems, consisting of AOT (dioctyl sulfosuccinate sodium salt), water and 3 kinds of n-alkane (hexane, octane and decane). The observed SANS profile was analyzed by two different models; one is a traditional Ginzburg-Landau model and the other is a product of a particle form factor and a structure factor. In the second model, a particle form factor of polydisperse spherical droplets and a structure factor of hard-sphere with the adhesive inter-droplet potential were used. The first model explained the broad peak profile only at low Q range and the second did at all the measured Q range. From the fitting by the second model, the stickiness parameter was estimated and it increased with increasing the carbon number of n-alkane. This result indicates that the interaction between droplets increases with increasing carbon number. This tendency is almost the same as increasing pressure. |
