Abstract: An anti-icing coating having a continuous phase and a discrete phase. The continuous phase includes a fluorine-containing polymer formed from a fluorine-containing precursor having a functionality of greater than 2. The discrete phase includes a plurality of domains having a fluorine-free hygroscopic and/or hydrophilic material. The plurality of domains are dispersed within the continuous phase and are immersible with the continuous phase. At least a portion of the fluorine-free material is bonded to the fluorine-containing polymer with an isocyanate-containing moiety. The fluorine-containing polymer is crosslinked with a crosslinking molecule having at least 4 functional groups. The fluorine-free material is a poly(ethylene glycol).
