Figure 3.40 Phase contrast optical image of a monolayer crystal of poly(ethylene oxide) grown at 55°C in a 10 pm molten film. Edges of the 22 nm thick lamella are revealed by self-decoration after quenching. The 6-axis is vertical and the a -axis is horizontal this shape may be compared with that in Figure 3.9. Width of the micrograph is 150 pm. From Kovacs and Gonthier [57] with kind permission from Springer Science-tBusiness Media B.V.

Figure 3.41 Transmission electron micrograph of a polyethylene crystal grown at 130°C from a molten film. A screw dislocation was centered in the etched hole abont which spiral growth has started. Scale bar is 2 pm. From Al-Raheil and Al-Share [58] with permission from John Wiley Sons, Inc.
