Experimental SWAXS spectra (ID02, ESRF) of three samples near the binodal, at mass fractions in octan-1-ol/ethanol/water of (a), (d) 0.188/0.373/0.439 for the water-rich sample, (b), (e) 0.4735/0.3227/0.2038 for the bicontinuous sample and (c), (f) 0.5864/0.2657/0.1479 for the oil-rich sample. Solid red lines are best fits to the two-contribution model [equation (1)[link]], dashed green lines are the OZ contributions, and dotted dark-orange lines are the Lorentzian functions for dense clusters of hydroxy groups. Plots (a)–(c) are on a double logarithmic scale and plots (d)–(f) are on a double linear scale. The deviation at high Q can be avoided if the constant background used in these plots is replaced by the sum of the Lorentzian functions fitting the WAXS peaks (see e.g. the fits in Fig. 1[link]). Similar plots for samples further away from the binodal are shown in Fig. S5 in the supporting information.
