Figure 1

(A) A schematic illustration of the reversible thermosensitive transition of poly(NIPAAm) (dark green lines) between the random coil and collapsed globule conformations, governed by entropy-driven interactions with water molecules (light yellow dots). The red dashed lines in the inset indicate possible hydrogen bonding between water molecules and the substituents of the polymer chain. (B) A schematic illustration of the process in which grafted linear poly(NIPAAm) chains on a laterally fluidic surface can condense in the presence of an external stimuli and further aggregate to form clusters.
