Figure 1.

AFM height images (2.5×2.5 μm²) of ULC nanogels in situ adsorbed on a PAH‐coated glass substrate in the hydrated state at various temperatures (above and below the VPTT). The same position is imaged at the different temperatures as identified by the dirt contamination (F, marked in black). The images were obtained by applying a force of SP=500 pN resp. 300 pN (in collapsed resp. swollen state) in Peak Force tapping mode. The temperature was varied in 2 °C‐steps (A–E) starting at T=35 °C (A), decreasing until a temperature of T=27 °C is reached (E) and afterwards heating again to T=35 °C (F).
