Figure 6
Scattering contribution of the Si block and the initiator layer to the general scattering intensity of the PEG microgel (a) and PNIPAM brush (b) simulated in the grazing-incidence geometry. All simulations are performed against D2O. The light-blue dashed–dotted line is the scattering signal from the neat Si block, the blue dashed line that from the Si block coated with the initiator layer (in the case of the PNIPAM brush), and the black solid line is the scattering signal from the corresponding polymer system onto the Si block. The red line indicates the q value at which GINSES measurements were performed. |
