SEM micrographs of surface microstructures of the pure PTFE and PTFE/PPS coatings. SEM micrographs of surface microstructures with different magnifications of the pure PTFE coating surface (P1 coating) (a ×600, b ×2,000, c ×10,000) and PTFE/PPS superhydrophobic coating cured at 390°C under H2 atmosphere (P2 coating) (d ×600×, e ×2,000, f ×10,000). The insets show the behavior of water droplets on their surface: (a) WCA = 136° and (d) WCA = 170°.
