We study the confinement of a hydrophilic polymer (polyethylene glycol or PEG) between the bilayers of the zwitterionic surfactant tetradecyldimethyl aminoxide (C(14)DMAO). Small angle X-ray scattering and electron microscopy experiments show that the polymer modifies the physical properties of the lyotropic smectic (L(alpha)) phase. The observed effects are similar to those reported for anchored hydrophobically-modified polymers, indicating a strong interaction between PEG and the C(14)DMAO… Expand

Effect of a neutral water-soluble polymer on the lamellar phase of a zwitterionic surfactant system.
The results of Freeze-Fracture Electron Microscopy and Small Angle X-ray Scattering experiments show that the addition of the polymer induces the spontaneous formation of highly monodisperse multilayered vesicles above a threshold polymer concentration. Expand
Elastic Properties of Polymer-Decorated Membranes
Polymers attached to one side of a fluid membrane induce a spontaneous cur- vature Msp of the membrane and change its elastic constants. For an ideal polymer in the mushroom regime, we determine MspExpand
