Figure 7
(a) Intermediate scattering functions of the PEG microgels measured in the bulk (blue) and adsorbed state at an incident angle of 0.35° (red) and 1.0° (green) (Gawlitza et al., 2015). (b) Schematic illustration of the evanescent wave intensity distribution within a PEG microgel according to the simulation from Fig. 5. The red–green color transition indicates depths probed at different incident angles in grazing-incidence geometry; colors correspond to the data in (a). The shape of the red–green figure schematically represents the shape of the PEG microgel. |
