Abstract
-perfluorodecyltriethoxysilane leads to superhydrophobic properties, and the equilibrium temperature of the coating is up to 71.1 °C at 1 solar irradiation because of the photothermal effect of carbon black. The results of the analysis of anti-icing/deicing properties of the coatings to evaluate their potential for engineering applications demonstrate that it takes longer time for ice to form on the coated surface than on a substrate without coating, and the ice completely melts under sunlight after 10 min and falls off automatically by its weight for the addition of 30 wt% carbon black and above, showing excellent deicing performance. Both types of substrates show excellent adhesion with the superhydrophobic coating, which can be classified as class 1 based on the paint and varnish-cross-section test method, and the ceramic material exhibits better adhesion than the glass.
