Fabrication of superhydrophobic coating with enhanced stability and anti-icing performance

Ice accretion on outdoor equipment detrimentally affect their performance and increase the maintenance cost. Significant advancements have been made in the development of superhydrophobic coatings for anti-icing, however, the intricate manufacturing procedures and limited stability remain primary challenges that hinder their widespread use in practical application. In this context, a durable superhydrophobic coating has been fabricated using a simple spraying technique, achieving a contact angle of 166.7±1.4° and a roll-off angle of 0.6±0.2°. The coating exhibits excellent stability with contact angle maintained above 160° after undergoing various examinations. Meantime, the superhydrophobic coating possesses an enhanced anti-icing property with the time to ice formation prolonged to 42.8 min. This stable superhydrophobic coating, suitable for various outdoor uses, is hoped to contribute to the development of eco-friendly anti-icing coatings.
