Phase separation in membranes incorporating components functionalized with water soluble polymers exhibits novel features. These occur because the domain rich in functionalized components is decorated by a polymeric brush. Three main scenarios may occur; i) phase separation with a lowered interfacial free energy between the domains, ii) formation of modulated phases, iii) repression of the phase separation. While the discussion focuses on the collapse behavior of a single polylipid anchored to a membrane, the conclusions apply to a wide variety of systems.
