“…These surfaces have a number of practical applications in various areas such as cleaning coatings [31], biomédical [10], anti-icing [30,32,33], anti-fouling [34,35] and anticorrosion [32], anti-sticking surfaces [36], anti-contamination of glass surfaces such as windows in buildings and windshields in vehicles [37]. Several studies showed a good correlation between hydrophobicity, especially superhydrophobicity and icephobicity of surfaces [7,30,32,[38][39][40][41][42][43]. Hence, the fabrication of hydrophobic and superhydrophobic surfaces has much promise in anti-icing application.…”

“…According to Ji et al [41], the use of Toluene in atmospheric pressure plasma polymerization HMDSO improves the hydrophobicity of a coating. They showed that the contact angle of untreated glass, which is about 50°, was increased to 135° after depositing the plasma polymerized HMDSO coating; with the plasma polymerized HMDSO/Toluene thin film it showed a superhydrophobic surface (contact angle ~ 150°, Figure 11.12).…”

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.

Superhydrophobic coatings are essential to prepare water-repellent surfaces, self-cleaning materials, etc. Silica nano-materials are often immobilized to different surfaces for imparting super-hydrophobicity. Direct coating of silica-nanoparticles is often challenging since it can easily be peeled off under different environments. Herein, we reported the use of properly functionalized polyurethanes to facilitate the strong binding of silica-nanoparticles to surfaces. The alkyne terminal polyurethane was synthesized by step-growth polymerization while click-reactions facilitated to post-functionalization using phenyl moiety and were characterized by 1 H, 13 C nuclear magnetic resonance (NMR) spectroscopies, and 1 H spin-lattice relaxation times (T 1 s). Upon functionalization, the glass transition temperature (Tg) increased due to enhanced interchain interactions. Moreover, additives like di-(propyleneglycol)dibenzoate showed a substantial plasticizing effect to compensate for the increase in Tg, an important parameter for low-temperature applications. NMR signatures the spatial interactions between various protons of grafted silica-nanoparticles and phenyl triazole functionalized polyurethanes, thus indicating the usefulness of polyurethanes to bind silica-nanoparticles. After coating functionalized silicananoparticles to leather using functionalized polyurethanes, a contact angle value of more than 157°was observed with retention of grain patterns of leather due to transparency. We anticipate the results to help design varieties of materials with superhydrophobicity where the structural integrity of the surfaces is retained.

Surfaces with water contact angles above 150° are regarded as superhydrophobic. In this study the use of atmospheric pressure plasma jet system called PlasmaStreamTM to deposit superhydrophobic coatings is investigated. The coatings were deposited from the following liquid precursors: hexamethyldisiloxane (HMDSO), tetramethyl cyclotetrasiloxane (Tomcats) and a mixture of Tomcats and fluorosiloxane. The objective of the study is to investigate how precursor type and deposition conditions, influences the morphology and mechanical performance of the deposited superhydrophobic coatings. Optical profilometry, AFM, SEM, Ellipsometry, XPS, Water contact angle and FTIR techniques were used to evaluate the surface roughness, morphology, thickness and chemical functionality of the deposited coatings. The mechanical properties were evaluated using the Nano Tribometer, Nano Scratch, Ultra Nanoindentation and ultrasonic abrasion tests. Superhydrophobic coatings deposited from a precursor mixture of Tomcats and fluorosiloxane yielded a substantial enhancement in coating adhesion and mechanical durability compared to the superhydrophobic coatings obtained with either Tomcats or HMDSO precursors alone.
