摘要：
The properties of viscoelastic dilute aqueous solutions containing the hexadecyltrimethylammonium cation (CTA+) are investigated by monitoring the proton magnetic resonance spectrum and the linear dichroism induced in a shear gradient. It is found that the viscoelastic behavior of the dilute solutions correlates with the formation of rod-shaped micellar aggregates. This correlation is manifested both with respect to changes in composition and in temperature. It is suggested that the behavior of the solutions is caused by the presence of a periodic colloidal structure formed due to the repulsive force between the aggregates. © 1979 American Chemical Society.
