要旨:
SANS measurements were performed for the ternary microemulsion D2O-octane-[n-dodecylpenta(oxyethylene glycol) monoether (C12E5)] at several compositions: (1) as a function of C12E5 wt fraction [gamma] at constant oil/water wt ratio [alpha] ([alpha] = 0.4, so the oil-to-water volume ratio is one); and (2) as a function of [alpha] (at [gamma] = 0.07 wt fraction) through the main isotropic channel. A formalism recently developed by Teubner & Strey [J. Chem. Phys. (1987), 87, 3195-3200] was used to describe the scattering data. Some problems with the fitting of the data are discussed. The values obtained for d, the domain size, from these fits agree rather well with the conduit sizes measured by electron microscopy.
