Fig. 24.6 Process of the preparation of double roughness structures. (1–6,7a,8a,9a): the surface
illustrated by pale blue and dark blue colors correspond to crystals of 1o and 1c, respectively.
SEM images of each surface: (7b) a surface with rod-shaped crystals of 1c, (8b) the surface after
irradiation with visible light to that of 7b, (9b) the surface after second UV irradiation to that of 8b
followed by storing it at 50 °C for 1 h in dark; (7c, 8c, 9c) the side view of the surfaces of 7b, 8b,
and 9b, respectively; (7d, 8d, 9d) water droplet (1.5 µL) on surfaces of 7b, 8b, and 9b, respectively.
Scale bars and magnifications, 10 µm and 1000 times for 7b–9b; 5 µm and 2000 times for 7c–9c
