Three γ-form crystal growth directions in nylon-12 rods correspond to different γ-cell orientation with respect to the long axis of the rod. (a) The γ-form crystal growth direction in the long axis of the rod is along the [200] direction as determined by the SAED pattern in Fig. 3(b), or (b) in between the [200] and [20] directions in Figs. 3(c) and 3(g), or (c) in between the [] and [001] directions in Figs. 3(d), 3(f) and 3(h). |
