Characterization by Confocal Laser Scanning Microscopy of the Phase Composition at Interfaces in Thick Films of Polymer Blends

Figure 4

Confocal images collected @530 nm of as casted unfiltered samples: (a) and (b) 1 : 1 glass/blend interface and blend/air interface, respectively; (c) and (d) 1 : 2 glass/blend interface and blend/air interface, respectively; (e) and (f) 2 : 1 glass/blend interface and blend/air interface, respectively (23.04 × 23.04 μm, 0.09 μm/px, 512 × 512 px) (color online). (g) The corresponding total PL counts (total counts integrated all over the image area) as detected by the instrument.
