Measured contact angle of DI water as a function of time after surface treatment for different surface topographies (polished, ripples, spikes) with either no coating, a thin coating (130 to 140 nm) or a thick coating (1070 to 1080 nm) of different coating material (SiOx, PP). The insets to the right of the plot show exemplary images of the water droplets on the surface and the corresponding contact angle. The contact angle areas of superhydrophobic (θ > 150°) and superhydrophilic (θ < 10°) states are indicated in green and blue, respectively.
