Fig. 4 — Neutron reflectivity profiles expressed as log(neutron reflectivity, R) versus momentum transfer (Q) recorded in different solvent contrasts after addition of 0.1 wt% PNIPAAM₄₁-b-PAMPTMA(+)₂₄ copolymer in 1 mM NaCl to silicon substrate at 20 °C (A) and 46 °C (B). Symbols: D₂O (green symbols), H₂O (blue symbols), and a D₂O/H₂O mixture (red symbols). Error bars given as ±std. Insets: Variation of the scattering length densities (SLD) as a function of distance from the interface in each case
