Scattering curves of CMK-8 with 0, 20, 40, and 50 wt % sulfur loading (a), the inset shows the non-shifted data magnified around the Bragg peaks, and fits of the modified Porod law (b). Kratky plot of the pore scattering with corresponding CLD fit (c) and CLD (d). The inset shows the Porod length lP (black) and from the CLD fit (red).
