A torrent intercepts the ionic flow in a polyelectrolyte solution.

An anomalous flow response of electric properties was observed in 0.01 wt% aqueous solutions of polyacrylic acid sodium salt (NaPAA) by electric measurements under shear flow using a newly developed apparatus. This response is considered to be caused by the migration of PAA ions being intercepted by the turbulent flow generated by the high shear rate, resulting in the inability to form macroscopic polarizations.
