A pulsed gradient spin-echo FT 1H NMR study on the system soybean lecithin/water/perdeuterated cyclohexane is presented. The self-diffusion coefficient of water, Dw, was measured as a function of the water content (W0) and was found to show a bell-shaped trend. The composition at which the maximum in Dw occurs is the same at which the viscosity is the highest. We rationalize the rising part of the plot in terms of a water diffusion inside wormlike reverse micelles which increase their length… CONTINUE READING
