Abstract
We present pulsed-field-gradient NMR and time-resolved small-angle neutron scattering experimental data to bear out the polymer-like nature of long, flexible micelles in the lecithin—water—cyclohexane system. The molecular transport of lecithin is described in terms of curvilinear lateral diffusion along the contour length of unbranched entangled cylindrical micelles. Moreover, an isotropic-to-nematic phase transition is induced under shear, characterized by a certain degree of alignment of the micelles. As a final result the lecithin micelles appear to be more polymer-like than wormlike micellar systems in general.
