Abstract
The temperature dependent theological and structural behavior of a long-chain C16E4 (tetraethylene glycol monohexadecyl ether) surfactant in D2O has been studied within the regime of low shear range. In the absence of shear flow, the system forms a lamellar liquid crystalline phase at relatively high temperatures. The present paper reports on the shear-induced multi-lamellar vesicle (MLV) formation in C16E4/D2O at 40 wt.% of surfactant in the temperature range of 40-55 degrees C. The transition from planar lamellar structure to multi-lamellar vesicles has been investigated by time-resolved experiments combining rheology and nuclear magnetic resonance (rheo-NMR), rheo small-angle neutron scattering (rheo-SANS) and rheometry. The typical... (More)
