“…The contact angle and work of adhesion of the polar liquids for Samples 1–3 are shown in Figure 8(a,b), respectively as per the procedure described elsewhere [43]. Ideally the static CAs of the sample should be found experimentally using a series of probe liquids, with a balanced composition of polar and non-polar components.…”

The wettability of reactively sputtered Y2O3, thermally oxidized Y-Y2O3 and Cd-CdO template assisted Y2O3 coatings has been studied. The wettability of as-deposited Y2O3 coatings was determined by contact angle measurements. The water contact angles for reactively sputtered, thermally oxidized and template assisted Y2O3 nanostructured coatings were 99°, 117° and 155°, respectively. The average surface roughness values of reactively sputtered, thermally oxidized and template assisted Y2O3 coatings were determined by using atomic force microscopy and the corresponding values were 3, 11 and 180 nm, respectively. The low contact angle of the sputter deposited Y2O3 and thermally oxidized Y-Y2O3 coatings is attributed to a densely packed nano-grain like microstructure without any void space, leading to low surface roughness. A water droplet on such surfaces is mostly in contact with a solid surface relative to a void space, leading to a hydrophobic surface (low contact angle). Surface roughness is a crucial factor for the fabrication of a superhydrophobic surface. For Y2O3 coatings, the surface roughness was improved by depositing a thin film of Y2O3 on the Cd-CdO template (average roughness = 178 nm), which resulted in a contact angle greater than 150°. The work of adhesion of water was very high for the reactively sputtered Y2O3 (54 mJ/m2) and thermally oxidized Y-Y2O3 coatings (43 mJ/m2) compared to the Cd-CdO template assisted Y2O3 coating (7 mJ/m2).

“…Barshiilia et al [9] prepared three different zinc oxide based coatings and discussed the effect of surface morphology on the adhesion, static and dynamic contact angle of water. Aytug et al [10] combined magnetron sputtering with thermal processing and differential etching to obtain nanostructured SHP thin films.…”

“…Perez et al [11] utilized Al-x at.%Zn (x = 3, 6, 10, 16, 19) PVD coatings to study the influence of metallurgical states on the corrosion behavior, while neglecting how different surface morphology might affect the wettability. To the best of our knowledge, the literature [9,[12][13][14] mainly explored ZnO SHP films obtained by sputtering zinc target, followed by annealing treatment. At present, studies on the Al 2 O 3 -ZnO SHP films fabricated through the analogous process still remain relatively scarce.…”

“…In the past, many researchers have tried to improve the hydrophobicity of solid film by radio frequency (RF) magnetron sputtering [19]. Barshiilia et.al prepared three types of ZnO based coatings and analyzed the effect of surface morphology on the wettability [20]. Ma et.al obtained ZnO micro-nano composite hydrophobic films via the three-step method including sol-gel dip-coating method, RF magnetron sputtering and hydrothermal method [21].…”
