The SANS experiments were performed on the KWS-1 beamline [30] at Heinz Maier-Leibnitz Zentrum (Garching, Germany). The samples were measured in standard Hellma quartz cuvettes with a path-length of 1 mm and kept at 25 °C throughout the experiment. For the measurements, a neutron wavelength of 7 Å was used. To cover the desired Q-range, the samples were measured at three sample to detector distances of 19.6 m, 7.6 m and 1.6 m for 1200 s, 600 s and 300 s respectively. Calibration to absolute intensities was done using poly(methyl methacrylate) (PMMA) as a secondary standard. For data correction, merging and reduction (azimuthal averaging) the toolkit QtiKWS by JCNS was used. The shape model (core-shell-shell sphere) is commonly used and readily available in most software. The model-dependent data analysis was carried out using the macro IRENA for IgorPro.
