Fabrication of robust and durable slippery anti-icing coating on textured superhydrophobic aluminum surfaces with infused silicone oil

Superhydrophobic Coating Based on Porous Aluminum Oxide Modified by Polydimethylsiloxane (PDMS)

“…Polydimethylsiloxane is a polymer with a wide range of applications due to its chemical stability, resistance to biodegradation, optical transparency, and favorable mechanical properties [ 27 ]. Many publications describe the use of polydimethylsiloxane (PDMS) to achieve superhydrophobic coatings (including coatings on aluminum), using anodized aluminum oxide as a template to form PDMS nanopillars, and using PDMS in the production of stamps to transfer a lotus leaf structure onto a selected substrate [ 16 , 17 , 18 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 ]. However, using PDMS to impregnate a porous aluminum coating in order to obtain a superhydrophobic surface in a process similar to the one described within this paper has not been recognized in the available literature.…”

Fabrication of a Porous Slippery Icephobic Surface and Effect of Lubricant Viscosity on Anti-Icing Properties and Durability

“…Researchers have prepared many SLIPS materials because of their potential applications, such as self-cleaning [17], anti-corrosion [18,19], anti-frosting [20,21] and anti-icing [19,22] features. Additionally, the lubricant layer on the SLIPS displays slippery properties leading to a minimized adhesion between the surface and the ice [23,24]. A lubricant has mobility, and thus can allow self-healing properties [18,25].…”

“…SLIPSs can be obtained by infusing a lubricant into a porous structure. The porous structure of SLIPSs has been prepared in several ways, such as chemical etching [24], porous polymer, self-assembly, and chemical deposition [20]. Anodic oxidation is a common approach to improving the abrasion resistance of an aluminum surface.…”

Chemical Fabrication Strategies for Achieving Bioinspired Superhydrophobic Surfaces with Micro and Nanostructures: A Review

“…[68,69,71] Moreover, the low-surface-energy materials such as PDMS and ACNT can be deposited directly on the substrates by CVD technique to form superhydrophobic surfaces. [55,61,62,67] There is no additional modification process required.…”

“…After deposition of 5 h, film structures covering the chemically etched Al surface were formed gradually by the directional connection between hydrophobic SiO 2 nanoparticles, which ensured the achievement of a superhydrophobic Al surface with a WCA of 158.7° ( Figure a). In 2019, Barthwal et al [ 62 ] also coated an etched Al substrate with a PDMS film to produce a superhydrophobic surface using a similar method. Tan et al [ 63 ] deposited a layer of low‐density isotropic pyrocarbon (LDIP) on a graphite disk substrate by virtue of CVD technology under 1550 °C and the flow rates of propylene, argon, and hydrogen were 1:10:15 for 30 h. The LDIP is composed of nanoparticles with special microscopic characteristics, creating unique micro/nanosized litchi‐like hierarchical structures, which can generate superhydrophobicity and superoleophilicity without low‐surface‐energy modification (Figure 1b,c).…”
