... (182.08 eV) and Zr–O (184.48 eV). The results verify that HPSi and hydrolytic condensation of zirconium alkoxide reduce the surface energy of the substrate and contribute to the strong mechanical properties of the fabricated hydrophobic coating. The microstructures and roughness of the prepared coating...

In this study, using aluminum sheets as substrates, some hydrophobic ratchet surfaces with different geometric parameters...

... on the spray–dry–cure method to establish a hydrophobic sol–gel coating on a lignocellulosic coir fibre surface. The fibres were first activated with oxygen plasma to ensure spreading of the droplets and thus coating uniformity. The efficiency of this method was highlighted by the high content of fluorine...
