Icephobicity of Oil-Infused Silicone Elastomer Coatings: Ice Adhesion, Freezing Time, and Room-Temperature Characterization.

ABSTRACT: Passive anti-icing coatings are a promising solution to the dangers of ice accumulation on surfaces. We studied plain polydimethylsiloxane (PDMS) and (commercially available) NuSil R-2180 coatings alongside PDMS coatings infused with two molecular weights and percentages of silicone oil. The icephobicity of the coatings was measured via ice adhesion strength and freezing time. 100 repeated deicing cycles were performed, which showed the oil-infused coatings had consistently lower ice adhesion strengths (∼10-20 kPa) than nonoil-infused coatings (∼100 kPa). The nonoil-infused coatings also showed increasing instances of exceptionally high ice adhesion strengths (>650 kPa), reducing the reliability of their icephobicity long-term. Oil infusion did not negatively affect the freezing time of th
