Photographic images of the water droplet on the surface and contact angles of the samples. Photographic images of the water droplet on the surface of (a) ZnO nanorods with no seed layer, (b) ZnO NRAs/zinc acetate seed layer, (c) ZnO NRAs/MWCNT (2 wt.%)-composed seed layer, and (d) ZnO NRAs/MWCNT (5 wt.%)-composed seed layer on ITO/glass and the measured contact angles of the corresponding samples.
