Dynamic of Laponite solutions: an interpretation within the coupling model scheme

The basic predictions of the coupling model (1) have been tested on Laponite suspensions at different clay and salt concentrations. In spite of parameters obtained through a fit analysis slightly different from that predicted by the coupling model, several interesting results consistent with the model have been found. These findings can open a new route to the interpretation of the intriguing dynamical behavior of this widely studied and discussed charged colloidal system.
