“…Several test methods have been reported to assess the mechanical robustness of superhydrophobic surfaces, such as sandpaper wear, tape stripping, sand erosion tests, pencil or knife scratch tests, and liquid impact tests [16,17]. Among these, the sandpaper abrasion test is the most common method for evaluating the mechanical robustness of superhydrophobic surfaces.…”

The physical mixing of inorganic fillers and a polymer matrix is a common method for constructing superhydrophobic coatings. Nevertheless, the interface bonding strength between the polymer and nanofiller was weak. The construction of interacting covalent bonds is a potential solution. In this study, carbon nanotubes were modified by aminopropyltriethoxysilane (APTES) and fluorosilane, and the reaction between the amino groups in APTES and -NCO(curing agent N3390) improved the bonding strength. Thus, the coatings maintained superhydrophobicity even after 260 abrasion cycles, 200 tape-peeling cycles, 18-day heat treatment, and acid/alkali attack. Furthermore, the corrosion current density could be reduced by three orders of magnitude compared with that of bare steel.

Anti-icing is crucial for transmission conductors to avoid long-term power outages caused by severe icing climates. Here, superhydrophobic aluminum conductors with composite honeycomb nanopore structures were prepared by the twice-anodic oxidation method. Effects of the anodized current density on the surface morphology, structure, hydrophobicity, and anti-icing performance were experimentally studied. As the current density increases, the film thickness of the lower layer of a small nanopore structure increases, while the dissolution effect on the upper layer of a large nanopore structure is strengthened. Also, the composite nanopore structure exists in the damaged condition and has a rougher surface at the micron level. By comparing the surface wettability and anti-icing performance of all samples, the sample under the current density of 0.01875A/cm2 showed the optimal anti-icing properties, including a contact angle (CA) of 168°, the ice adhesion force of 4.87 kPa, and the longest frost formation time. The good anti-icing performance makes the anodized aluminum of composite nanopore structures a satisfactory candidate for improving their anti-icing behavior in the industry.

“…Liu et al have reported a durable anti-icing superhydrophobic anodic alumina surface [1]. Xiang et al also confirmed the anti-icing performance of anodized aluminum strands [1,12]. Therefore, further considering the anodic oxidation method to achieve precise control of the nanopore's structure can achieve the preparation of good a anti-icing Al surface for complex aluminum strands.…”

Icing on transmission lines often causes potential electric damage in power systems. Superhydrophobic anodized Al conductors have been proposed to have good anti-icing properties. In this study, superhydrophobic anodized Al conductors with composite nanopore structures were prepared by a two-step anodization. The microstructure, hydrophobicity, and anti-icing properties of composite nanopore structures were compared and studied. The optimal preparation parameter was determined as a current density of 0.04375 A/cm2 and anodization time of 15 min. Compared with the bare substrate, the optimal anodized Al surface of the composite nanopore structures show excellent hydrophobic and anti-icing properties, including a contact angle of 173°, a contact angle hysteresis of 0.122°, an ice adhesion strength of 0.71 kPa, and a glaze icing weight of 0.1 g after the 8 h. Therefore, the prepared anodized Al surface of composite nanopore structures with good anti-icing properties has profound application potential for overhead transmission lines.
