“…Since then, the superhydrophobic and superhydrophilic surfaces have been paid close attention owing to their very special wettability and important applications. [3][4][5][6] Superhydrophobic surface is defined as a surface with a static water contact angle (CA) larger than 150° and a sliding angle (SA) lower than 10°. Superhydrophilic surface refers to the surface with a static water CA lower than 5°.…”

Superhydrophilic surface with a static water contact angle of 4±2º via two-step immersion process and superhydrophobic surface with a static water contact angle of 169±2º and a sliding angle of almost 0º via succedent thermal treatment have been successfully fabricated on alumin um substrates. The surface morphologies and chemical compositions were investigated using field emission scanning electron microscopy, x-ray powder diffraction and x-ray photoelectron spectroscopy, and the formation mechanism was also analyzed. The thermal treatment which causes the generation of oxides and the appearance of nano-sized particles is very important for the surface characteristic transformation from superhydrophilicity to superhydrophobicity. The effects of various experimental parameters on wettability, corrosion resistance, anti-icing and deicing properties, stability and large-area preparation were also studied. The corrosion rate of the asprepared superhydrophobic surface decreases by about 57.6 times compared with that of the untreated aluminum surface and appropriately 34.8 times compared with that of the pure copper surface. These excellent properties of the superhydrophobic surface may be favorable for its potential applications and industrialization.

Due to their superior water-repelling effects, superhydrophobic surfaces have received increasing attention as a promising solution to corrosion of metallic materials. The present article introduces the fundamental theories behind superhydrophobicity followed by a comprehensive review of the recent progresses of this rapidly growing field over the past 5 years. A critical discussion over anticorrosion mechanisms of superhydrophobic surfaces is also provided. For many realistic applications, future efforts are pressingly demanded to prolong the corrosion resistance of these superhydrophobic surfaces. To this end, several important strategies and examples in designing stable, selfhealable, or inhibitor-loaded superhydrophobic surfaces are discussed.

“…Finally, three images were analyzed using the supplied software to determine the contact angle. For each sample, the contact angle measurement was repeated on five randomly selected areas on the surface of the bioelectrode [24]. The average value of their contact angles was taken as the static contact angle of the samples.…”
