Fig. 6: Illustration of water residing within a representative hydrophobic film, with the majority of water present at the relatively rough polymer–water interface.

From: SMART transfer method to directly compare the mechanical response of water-supported and free-standing ultrathin polymeric films

Fig. 6

Layer 1 depicts decreasing water content with increasing distance from the film–water interface followed by a reduced water content in layer 2. “Wet” and “dry” polymer chains are depicted on the right, illustrating that the water resides within pre-existing voids throughout the film and does not swell the polymer chains.
