Textile material fibers coated with ZnO: (a) NP deposited by PLD with 10 pulses, (b) TF deposited by PLD with 100 pulses.
2D AFM topography images for the TF deposited in (a),(c) a 13 Pa oxygen flux and (b),(d) vacuum at different scales: (a),(b) (10 × 10) μm2 and (c),(d) (2 × 2) μm2.
SEM micrographs of ZnO NP deposited in a 13 Pa oxygen flux on a Si substrate. Target-substrate separation distance was of (a) 3 cm, (b) 4 cm, and (c) 5 cm. Inset: Water droplet in static mode and the measured CA.
