Phase-dependent shear-induced order of nanorods in isotropic and nematic wormlike micelle solutions

In situ shear was used to investigate the assembly and dispersions of gold nanorods embedded in wormlike micelle solutions made by the survivant cetylpyridinium chloride and counter-ion sodium salicylate, with in situ shear. The nanorods did not achieve hexagonal order in the micelles' nematic phase, but instead produced smectic-like layers in the gradient's gradient plane under shear, with higher surfactant concentrations. The nanorods eventually received a nematic-like order under shear as a result of alignment in the flow, at a higher surfactant concentration, where the micelles form a hexagonal phase.
