“…Comparably, the non-oiled nanoparticle coating alone cannot replicate the results either. As is highly probable based on the WSA measurements, water droplets get pinned to the surface, and thus, the ice will have a mechanical hold on the surface, resulting in mechanical interlocking effect 16 and an increased ice adhesion strength. All of the oiled samples were also notably better icephobic surfaces than the reference PTFE-tape (WCA ¼ 110 , WSA ¼ 10 ), which can be clearly seen in the lowest ice adhesion strength values of the PTFE-tape and the SLIPS, 44 and 9 kPa, respectively.…”

Slippery, liquid-infused porous surfaces offer a promising route for producing omniphobic and anti-icing surfaces. Typically, these surfaces are made as a coating with expensive and time consuming assembly methods or with fluorinated films and oils. We report on a route for producing liquid-infused surfaces, which utilizes a liquid precursor fed oxygen-hydrogen flame to produce titania nanoparticles deposited directly on a low-density polyethylene film. This porous nanocoating, with thickness of several hundreds of nanometers, is then filled with silicone oil. The produced surfaces are shown to exhibit excellent anti-icing properties, with an ice adhesion strength of ∼12 kPa, which is an order of magnitude improvement when compared to the plain polyethylene film. The surface was also capable of maintaining this property even after cyclic icing testing.

The icephobic performance of alkyl-grafted aluminum surfaces

et al. 2015

Abstract. The work analyzes the anti-icing performance of flat aluminum surfaces coated with widely used alkyl-group based layers of octadecyltrimethoxysilane, fluorinated alkylsilane and stearic acid as they are subjected to repeated icing/deicing cycles. The wetting properties of the samples upon long-term immersion in water are also evaluated. The results demonstrate that smooth aluminum surfaces grafted with alkyl groups are prone to gradual degradation of their hydrophobic and icephobic properties, which is caused by interaction and reactions with both ice and liquid water. This implies that alkyl-group based monolayers on aluminum surfaces are not likely to be durable icephobic coatings unless their durability in contact with ice and/or water is significantly improved.

“…This property is due to the surface micro/nano scale roughness and the hydrophobicity of stearic acid. Nevertheless, a few studies did not agree with this hypothesis [55,56], Chen et al…”

“…In most of the research studies, the accumulation of ice was performed in a wind tunnel in order to simulate real atmospheric ice conditions [7]. While in other cases, the delay time of water frozen on a surface was studied [55]. Sarshar et al [53] showed that the superhydrophobic surfaces can also lead to the delay of ice formation.…”

“…[ 55] have shown that hydrophilic and hydrophobic surfaces have a lower ice adhesion strength than superhydrophobic and superhydrophilic surfaces (see Figure II In order to investigate the relation between icephobicity and hydrophobicity, the following factors should be considered: the deposition of specific functional groups of a low surface energy material coating, the method of accumulating ice on the surface, the type of ice, and the morphology of the surface. The deposition of low surface energy materials leads to the creation of a hydrophobic coating, but the effect of specific functional groups can lead to improve hydrophobic characteristics.…”

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.
