Robust anti-icing coatings via enhanced superhydrophobicity on fiberglass cloth
https://orcid.org/0000-0001-5817-0182
AbstractRobust superhydrophobic coatings with anti-icing properties were obtained by a simple approach, i.e., immersing and spraying of adhesive/hydrophobic silica dispersion on fiberglass cloth. Scanning electron microscopy, water contact angles, abrasion tests and dynamic icing tests were performed to characterize the morphology, hydrophobicity, mechanical durability and icephobicity of the coatings. The experimental results demonstrated that the coatings have good abrasion resistance. The water contact angle and the water sliding angle remain greater than 150° and lower than 10°, respectively, after 60cycles of abrasion. Furthermore, the anti-icing properties of superhydrophobic surfaces were investigated under dynamic flow conditions. It was found that the coatings had the ability to delay ice nucleation without electrical heating, and avoid ice adhesion partly or even completely, under a given mass of heat, which was much less than that of uncoated surfaces. The fiberglass cloth based coatings could reduce by up to 51% of the heating power required to avoid ice accumulation, compared to uncoated surfaces.

HighlightsA simple method of fabricating robust superhydrophobic coatings was proposed.The fiberglass cloth based coatings showed good abrasion resistance.Good mechanical durability relied on the regular texture of fiberglass cloth.The coatings showed outstanding anti-icing performance.
