Figure 4
(a) Temperature-dependent RSOXS profiles of copolymer scattering as described in the text. Intensity has been scaled to an absolute unit by the responsivity calculated in Section 4[link]. Error is represented by the shaded region and was calculated by combining the profile standard error (as calculated from NIKA) with uncertainty in the thickness measurement. Thickness was measured from the photo-absorption and was determined to be 29 ± 1 nm. Gray lines are profile fits to equation (4)[link] with all relevant parameters given in Table 1[link]. (b) Extracted χ parameters from the fits in part (a). Error is calculated from the Levenberg–Marquardt algorithm used in fitting. The black line is a linear fit as discussed in the main text.
