Figure 7.16 Left Spreading of a drop of PDMS on a silicon wafer observed with an ellipsometer 19 h after deposition. Redrawn after Ref. [283], On a much smaller scale (right) prewetting layers around droplets of polystyrene on a flat silicon oxide surface are observed. The atomic force microscope image shows an area of (2.5 /um)2 [284].

The left picture shows aggregates of silicon oxide particles with a diameter of 0.9 pm (see example 1.1). At the bottom an atomic force microscope image of cylindrical CTAB micelles adsorbed to gold(lll) is shown (see example 12.3, width 200 nm). The right image was also obtained by atomic force microscopy. It shows the surface of a self-assembled monolayer of long-chain alkylthiols on gold(lll) (see fig. 10.2, width 3.2 nm).
