Abstract
A coating that is able to shed accumulated material (such as ice) that includes a crosslinkable copolymer with hydrogen bonding moieties and liquid-like side chains, and an oil (or other non-aqueous liquid) that is compatible with the side-chains and that resides in the crosslinked coating and on the surface of the coating together with the side-chains that are on the external surface. Methods may use the coating for de-icing, shedding of marine organisms, and smudge-repellency.
