Fig. 1.

Layer thickness d (upper panels) and adsorbed amount Γ (lower panels) determined by null ellipsometry, as a function of time after addition of PNIPAAM₂₄-b-PAMPTMA(+)₉ copolymer to silica at 20 °C (region I), followed by a temperature increase to 40 °C (region II), followed by addition of γ-CD at 20 °C (region III), and then followed by a temperature increase to 40 °C (region IV). The macromolecular concentrations are as follows: 0.005 wt% PNIPAAM₂₄-b-PAMPTMA(+)₉ in 1 mM NaCl and 0.05 wt% γ-CD in 1 mM NaCl
