Abstract:
In one embodiment, articles subject to ice formation during normal use are described comprising a repellent surface such that the receding contact angle of the surface with water ranges from 90 degrees to 135 degrees wherein the repellent surface comprises a fluorochemical material having a Mn of at least 1500 g/mole. The fluorochemical material typically has a molecular weight of no greater than 50,000 g/mole. In one embodiment, the repellent surface further comprises a non-fluorinated organic polymeric binder. In another embodiment, the repellent surface comprises a thermally processable polymer and a fluorochemical material melt additive. Also described are methods of making an article comprising providing an article subject to ice formation during normal use; and providing a liquid repellent surface, as described herein, on the article.
