Fig. 4. (a) Variable-temperature SWAXS profiles (left) and POM images (right; scale bar (sb), 50 μm) of DPA10 cooled from 30 to –30 °C, and then heated to –15, 0, 15, and 30 °C at 10 °C min–1 (top to down). (b) SWAXS profiles (left) and POM images (right; sb, 50 μm for (i–iii) and 100 μm for (iv–vi)) of DPA8: (i) freshly melted, (ii) annealed at –18 °C for 1 day, and subsequent aging at 15 °C for (iii) 1 day, (iv) 3 days, (v) 7 days, and (vi) 14 days. The sample area was denoted with asterisk (*) in the POM.
