1. A method for inhibiting the formation of ice on a surface, the method comprising applying to the surface one or more phase change materials, wherein the one or more phase change materials have a melting point in the range of 0° C. to 30° C., and wherein the phase change materials are selected from the group consisting of cyclohexane, peanut oil, corn oil, eucalyptol, 1-phenyl dodecane, phenyl-cyclohexane, fennel oil, 2′-hydroxy-acetophenone, ethyl cinnamate, anise oil, cyclo-octane, 2-heptyne, n-dodecyl acetate, oleic acid, benzene, nitrobenzene, cyclohexylbenzene, 1,2,3-tribromopropane, 2,2-dimethyl-3-pentanol, hexafluorobenzene, ethylene dibromide, tert-butyl mercaptan, bromoform, diiodomethane, bicyclohexyl, DMSO, 1-bromonaphthalene, ethylenediamine, and formamide,
wherein the one or more phase change materials are incorporated within a layer of a polymer; and
wherein the polymer is an organohydrogel.
