Abstract: Disclosed are compositions that may be useful for forming synthetic membranes, methods of forming membranes therefrom, and membranes. In an embodiment, a membrane comprises a free hydrophilic polymer and a polyurethane, the polyurethane comprising a backbone comprising the reaction product of a diisocyanate, a polymeric aliphatic diol, and, optionally, a chain extender, wherein the backbone comprises a C2-C16 fluoroalkyl or C2-C16 fluoroalkyl ether, or the polyurethane comprises an endgroup comprising a C2-C16 fluoroalkyl or C2-C16 fluoroalkyl ether.
