Figure 2
(a) XN images of the designed nanocomposite in accordance with the f value changes (top), and schematic illustration of the representative spatial distribution of AuNPs for each corresponding case (bottom). The repeated temperature starting from low temperature and then high temperature and then back to the original low temperature condition is defined as f = 1. AuNPs are homogeneously distributed at initial f = 0 [0] and form isotropic clusters at f = 10 [I]. However, the clusters elongate at f = 20 [II] and at f = 50 [III]. On further increase to f = 70 [IV], line formation becomes prominent. (b) Three types of temperature variation cycle at a fixed frequency of 0.125 min−1. The transition temperature for change is short enough to be neglected. The Type A symmetric temperature variation is designed with 4 min at 60°C and 4 min at 20°C; the asymmetric Type B with 6 min at 60°C and 2 min at 20°C; and Type C with 2 min at 60°C and 6 min at 20°C. (c) XN images of the nanocomposites in accordance with the designed types at a fixed state of f = 20. Wrinkling is accelerated in Type B. (d) None of the types generates line patterns even at a high f = 80 when a small volume change is induced by the temperature shift between 20°C and 50°C. |
