SEM images of (a, c, e, and g) hydrophobic pure siloxane and (b, d, f, and h) superhydrophobic siloxane-particle (2% w/v) films deposited on (a, b) modern blank, (c, d) modern printed, (e, f) old, and (g, h) Japanese paper. Specific areas of Figures (g) and (h) are revealed in higher magnification SEM images in Figures (i) and (j), respectively. The image in (j) corresponds to an area that exists between the protruded aggregates, indicated by the dotted line in (h). The area shown in (i) was randomly selected and is provided for comparative purposes. Photographs of water drops are shown in (a) and (b).
