This invention provides durable, low-ice-adhesion coatings with excellent ice-adhesion reduction. Some variations provide a low-ice-adhesion composition comprising a composite material containing at least a first-material phase and a second-material phase that are nanophase-separated on a length scale from 10 nanometers to less than 100 nanometers, wherein the first-material phase and the second-material phase further are microphase-separated on a length scale from 0.1 microns to 100 microns. The larger length scale of separation is driven by an emulsion process, which provides microphase separation that is in addition to classic molecular-level phase separation. The composite material has a glass-transition temperature above −80° C. The coatings may be characterized by an AMIL Centrifuge Ice Adhesion Reduction Factor up to 100 or more. These coatings are useful for aerospace surfaces and many other applications.
