Corrosion protection by hydrophobic silica particle-polydimethylsiloxane composite coatings

Water-repellent and corrosion-resistance properties of superhydrophobic and lubricant-infused super slippery surfaces

“…The value of |Z| 0.01 Hz of SLIPS was 10 7 U cm 2 , which was increased by two orders in comparison with the superhydrophobic surface. Similar to other reports, [42][43][44] the values of |Z| in the high-frequency range were evidently different between these four samples. The highfrequency limit of the Bode plots is supposed to represent the electrolyte resistance; the variation at 10 5 Hz was due to the air layer between the superhydrophobic interface and the solution, which made the electrolyte resistance for the superhydrophobic-coated Mg alloy larger than that for the untreated alloy.…”

Long-term corrosion protection by a thin nano-composite coating

“…Thin plasma polymerized HMDSO coatings have also been reported to have good stability when immersed in water [29], even though reorientation of surface groups and migration of polar molecules to the coating-water interface reduces the surface hydrophobicity with time. We recently reported enhanced corrosion protective properties for steel using a PDMS coating containing silica nanoparticles [30] and, subsequently, a HMDSO coating applied by the plasma process was chosen as a top coat on the surfaces fabricated here. Our results presented here show that the three-layer system combines these properties to provide excellent corrosion protection to the underlying carbon steel substrate.…”

Durable Self‐Healing Superhydrophobic Coating with Biomimic “Chloroplast” Analogous Structure

“…Biomimetic superhydrophobic surfaces, with water contact angle (WCA) greater than 150° and sliding angle (SA) smaller than 10°, have attracted significant attention in recent years due to their outstanding antiicing, anticorrosive, self‐cleaning, and drag‐reducing properties. It is well known that superhydrophobicity of solid surfaces is governed by both hierarchical surface structures and low‐surface‐energy materials .…”
