Memory effects across surfactant mesophases.

چکیده
We report a detailed analysis of deuteron NMR spectra of micellar, lamellar, cubic, and hexagonal mesophases in the aqueous non-ionic surfactant system C(12)E(6)/water. Samples are prepared with and without shear. Particular attention is paid to an interesting temperature-driven phase sequence that includes all of the above phases that are studied before and after shear parallel or perpendicular to the magnetic field direction. Surprising memory effects are found across mesophase transitions. These memory effects provide clues to the structure of the various phases.

On the Swelling of Bicontinuous Lyotropic Mesophases
The swelling of sponge-like bicontinuous mesophases of bilayers of surfactant (or lipid) in water as a function of dilution is analyzed. Analytic formulae for the swelling are derived assuming ii) constant aggregate thickness and (it) fixed surface area per surfactant molecule at an imaginary surface located within the bilayer. Approximate swelling laws are derived for bicontinuous films and co...
متن کاملConducting polymer nanofibers with controlled diameters synthesized in hexagonal mesophases
Oil-swollen hexagonal mesophases resulting from the surfactant mediated self-assembly of a quaternary mixture of water, surfactant, co-surfactant, and oil, are versatile templates to synthesize anisotropic nanomaterials. Poly(diphenylbutadyine) (PDPB) polymer nanofibrous network structures were produced in the oil tubes of the mesophases by photo-induced radical polymerization using a chemical ...
متن کاملMolecularly ordered inorganic frameworks in layered silicate surfactant mesophases.
Self-assembled lamellar silica-surfactant mesophase composites have been prepared with crystal-like ordering in the silica frameworks using a variety of cationic surfactant species under hydrothermal conditions. These materials represent the first mesoscopically ordered composites that have been directly synthesized with structure-directing surfactants yielding highly ordered inorganic framewor...

Surfactant mesophases mediated by colloidal particles
We have investigated effects of guest colloidal particles on the mesoscopic structures of a surfactant/water system by means of small angle neutron and x-ray scattering techniques. The addition of a small amount of colloidal particles between lamellar slits reduces the undulational fluctuations of lamellae and brings about a lamellar to micelle transition. On the other hand, on addition of coll...
