The Effect of Film Thickness on Lamellar Growth Rate and Morphology

The Effect of Film Thickness on Lamellar Growth Rate and Morphology 

The topographical AFM images of poly(ethylene vinyl acetate) films with various thicknesses ranging from 20 to 460 nm are shown in Fig. 33 [80]. The bulk-like spherulites are seen in the 460-nm film. In thick films, the surface morphology of the film is very similar to the bulk. As the thickness decreases to 152 nm, more small spherulites are observed. This is possibly due to the
