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

Figure 3

TEM images of iPS thin films crystallized via a temperature profile with = 160°C (a and b) and 178°C (c and d) on glycerol substrates (air/iPS/glycerol). A fibril-like texture is seen outside the edge of the film, as indicated by the arrow in (c).
