摘要：

We consider for the first time the consequence of flow fields on the size of micellar aggregates. In the case of extensional flow, we incorporate directly an effective potential into the conditions for self-assembly equilibrium. While the perpendicular component of the viscous forces serves mainly to align the rodlike micelles, the parallel contribution results in a deformation energy. This latter term imposes on the size distribution an upper cutoff which is a strongly decreasing function of velocity gradient. © 1990 American Chemical Society.
