Abstract
A coating includes at least one coating layer containing first particles, second particles, and third particles distributed throughout a cross-linked, continuous polymer matrix. An outer surface of the coating layer includes surfaces of at least first particles extending outward from a top periphery of the polymer matrix. The outer surface exhibits a property of delaying ice formation compared to the coating layer without the first particles. A method includes applying a coating composition in one application step. The one-step coating composition contains first particles, second particles, and third particles in a base containing a polymer. A coating composition includes first particles, second particles, and third particles distributed in a matrix precursor.
