Shear-induced sponge-to-lamellar phase transition studied by rheo-birefringence
(2004) In Colloid and Polymer Science 282(8). p.918-926- Abstract
- We report on the shear induced transition from the L-3- to the L-alpha-phase studied by means of flow birefringence using the system pentaethyleneglycol monododecylether (C12E5), decane, water. The dependence of the critical shear rate, at which the transition from the isotropic state to the anisotropic takes place, on membrane volume fraction was studied in temperature ramp experiments at different constant shear rates and in isothermal shear ramp experiments. These results are compared with relaxation experiments from the shear aligned state back to the isotropic. For all these experiments power law exponents in the membrane volume fraction between 1.6 and 2.8 were found, which are rather low compared to values of current theories. The... (More)
