“…The similar FT-IR spectrum results for W15 surface before and after 240 hours of UV exposure were achieved. Therefore, we concluded the PP-HMDSO coating deposited on anodized and water treated aluminum surfaces have a relatively good stability against UV degradation compared to other research work done by Hugan et al [148] that showed the superhydrophobic coating had changed to hydrophilic coating after 8 hours of UV exposure. It should be noted that 240 hours of exposure in the mentioned apparatus is equivalent to about six months of natural exposure in Canada (see section III.3.6).…”

Accumulated ice on exposed surfaces leads to operational difficulties and extensive maintenance for power transmission lines, antennas, aircraft, ships, and ground transportation vehicles.In the present study, the low pressure plasma polymerized Hexamethyldisiloxane (PP-HMDSO) film is deposited on aluminum surfaces to create a superhydrophobic coating with icephobic properties. Prior to the deposition of this low surface energy coating, aluminum surfaces were anodized or immersed in boiling water to make micro/nano structured surfaces.Plasma parameters were optimized in order to find the best optimum conditions for having high static contact angle and low contact angle hysteresis. Hence, the Grey-based Taguchi method was used as one of the Design of Experiment (DOE) techniques. The stability of coatings was studied under accelerated aging conditions such as UV degradation, immersion in distilled water and different pH solutions, and several icing/deicing cycles. It was observed that the PP-HMDSO coatings are quite stable against UV exposure and immersion in distilled water. However, the icephobicity of the PP-HMDSO coating deposited on the anodized aluminum decreased after fifteen icing/de-icing cycles.The stability of the developed coating was improved against several icing/de-icing cycles by increasing the deposition time of plasma polymerized coating from 15 to 25 minutes. The results showed that increasing the deposition time of plasma polymerization leads to decrease of the ice adhesion strength of coatings on anodized aluminum while it has no significant effect on the PP-HMDSO coating deposited on a water-treated aluminum surface. Finally, the superhydrophobic PP-HMDSO coating also provides anti-corrosion protection for the aluminum substrate.

“…Hydrophobic materials are commonly applied onto textured surfaces to promote hydrophobicity. Teflon [116,117], PFOS (perfluoro-octane sulfonates) [118], PDMS (polydimethylsiloxane) [119], and CNTs (carbon nanotubes) [120,121,122] are representative examples. CVD (chemical vapor deposition), PVD (plasma vapor deposition), and electrochemical deposition techniques are commonly used to coat these materials.…”

“…Shang et al prepared a transparent, superhydrophobic, silica-based surface film by introducing a nano-scale rough surface [1]. Huang et al confirmed that a superhydrophobic surface can be achieved by aligned carbon nanotubes coated with a thin zinc oxide film [2]. Lee and Michielson enhanced the surface hydrophobicity of nylon flock fabric by grafting with poly(acrylic acid) and 1H-1H-perfluorooctyl-amine [3].…”

This paper investigates the use of atmospheric pressure plasma (APP) treatment for improving the surface hydrophobicity of rayon flock synthetic leather with organosilane precursor (tetramethylsilane (TMS)). Plasma deposition of TMS is regarded as an effective, simple, and low-pollution process. The results show that a highly hydrophobic surface is formulated on the rayon flock synthetic leather. Under a particular combination of treatment parameters, a hydrophobic surface was achieved on the APP-treated sample with a contact angle of 135˝while the untreated sample had a contact angle of 0( i.e., the fabric surface was completely drenched immediately). Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and X-ray Photoelectron Spectroscopy (XPS) confirmed the deposition of organosilane.
