Measured contact angle of DI water as a function of time after surface treatment for different surfaces (ripples, spikes) obtained from laser texturing and plasma coating of a thin SiOx coating with a thickness of d = 140 nm. 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 area of a superhydrophilic state (θ < 10°) is indicated in blue.
