520 |a Preventing water droplets from transitioning to ice is advantageous for numerous applications. It is demonstrated that the use of certain phase-change materials, which are in liquid state under ambient conditions and have melting point higher than the freezing point of water, referred herein as phase-switching liquids (PSLs), can impede condensation-frosting lasting up to 300 and 15 times longer in bulk and surface infused state, respectively, compared to conventional surfaces under identical environmental conditions. The freezing delay is primarily a consequence of the release of trapped latent heat due to condensation, but is also affected by the solidified PSL surface morphology and its miscibility in water. Regardless of surface chemistry, PSL-infused textured surfaces exhibit low droplet adhesion when operated below the corresponding melting point of the solidified PSLs, engendering ice and frost repellency even on hydrophilic substrates. Additionally, solidified PSL surfaces display varying degrees of optical transparency, can repel a variety of liquids, and self-heal upon physical damage
