We report shear startup data on solutions of entangled linear wormlike micelles, only differing in the concentration of a binding aromatic salt. Wormlike micelles behave similarly to ordinary polymers in fast shear flows, exhibiting pronounced overshoots as well as tiny undershoots in transient shear viscosity, before approaching the steady state. The analogy is here emphasized by successfully comparing data with predictions of a constitutive equation recently adopted for ordinary entangled polymers. In the fast shear flow, entangled linear wormlike micelles appear to align, stretch, and tumble just like polymeric chains.

线性蠕虫状胶束在快速剪切流中的行为类似于缠结的线性聚合物

我们报告了缠结线性蠕虫状胶束溶液的剪切启动数据，仅在结合芳香盐的浓度上有所不同。蠕虫状胶束在快速剪切流中的行为类似于普通聚合物，在接近稳态之前，在瞬态剪切粘度中表现出明显的过冲和微小的下冲。通过成功地将数据与最近用于普通缠结聚合物的本构方程的预测进行比较，这里强调了类比。在快速剪切流中，纠缠的线性蠕虫状胶束似乎像聚合物链一样排列、拉伸和翻滚。
