Interfacial Effects on the Spherulitic Morphology of Isotactic Polystyrene Thin Films on Liquid Substrates

Figure 6

TEM images of iPS thin films crystallized between silicone oil and glycerol (silicone oil/iPS/glycerol); Au was deposited on the side that contacted with glycerol (a and b) and with silicone oil (c and d). The final crystallization temperature was 178°C. The arrow in panel (b) indicates a texture of dominant lamellae.
