A Brief Review on Bioinspired ZnO Superhydrophobic Surfaces: Theory, Synthesis, and Applications
Figure 8
FE-SEM images of the prepared film on a glass substrate at different magnifications. (a) shows a high density array of ring-like structures deposited on the substrate. (b) shows that the diameter of a ring is about 8 mm. (c) is the high-magnification image and shows that the rings surface was covered with a layer of rods. (d) indicates the distribution of the ring diameters. Copyright 2013, RSC.
