Filippelli, Luigi; Medronho, Bruno LU ; Rossi, Cesare Oliviero; Miguel, Maria G. and Olsson, Ulf LU (2009) 8th National Meeting of the Italian-Liquid-Crystal-Society In Molecular Crystals and Liquid Crystals 500. p.166-181
Abstract
Nuclear magnetic resonance spectroscopy and rheological analysis have been used to investigate the stability of mechanically induced tri-ethylene-glycol-mono-n-decyl-ether (C10E3)/deuterium oxide (D2O) multi-lamellar vesicles (MLVs) and the transition from MLVs to planar lamellae. It was found that MLVs prepared by vortex stirring, relax back to the lamellar phase in a few hours while the relaxation of the shear induced MLVs takes days. Pulsed gradient spin echo and water self-diffusion coefficient experiments, revealed that the MLVs texture, obtained by vortex stirring, is composed of large size structures. These data indicate that the kinetics of lamellar re-formation depend on the MLVs number density.
