Abstract.
We study the influence of nanoparticle doping on the lyotropic liquid crystalline phase of the industrial surfactant Brij30 ( C12E4 and water, doped with spherical polyoxometalate nanoparticles smaller than the characteristic dimensions of the host lamellar phase. We present viscometry and in situ rheology coupled with small-angle X-ray scattering data that show that, with increasing doping concentration, the nanoparticles act to decrease the shear viscosity of the lamellar phase, and that a shear-induced transition to a multilamellar vesicle “onion” phase is pushed to higher shear rates, and in some cases completely suppressed. X-ray data reveal that the nanoparticles remain encapsulated within the membranes of the vesicles, thus indicating a viable method for the fabrication of nanoparticle incorporating organic vesicles.

We use a pre-shear treatment rather than a quench into the low-temperature isotropic region of the phase diagram muller, as at 50% surfactant concentration there is no low-temperature lamellar-isotropic phase transition, as seen in the C_12E_4 phase diagram daffy and confirmed by observations of cross-polarised optical texture after a quench to 0^C

Shear viscosities measured here for the pure undoped lamellar phase at 40% surfactant concentration are around an order of magnitude higher than those given by Müller for a pure 40% C_12E_4 lamellar phase at equivalent shear rates muller. We can identify two reasons for this: previous experiments demonstrate that there is a clear effect of the nature of the cell material and surface roughness oops
