Kerr effect of Xanthan/DTAB aqueous solutions

Mostrar todas las versiones(2)

The Kerr effect of the Xanthan (charged polyelectrolyte; 113 ppm)/DTAB (surfactant) mixture in aqueous solution was studied. The static Kerr constant (B) and mean relaxation times (τ) values as a function of surfactant concentration (CDTAB) were determined. The observed birefringence (Δn) is not a l...
