| Abstract: | Effects of inorganic electrolytes on the micellar structure of Pluonic F108 and P94 in aqueous solutions have been investigated using UV-spectroscopy, fluorescence emission spectroscopy and viscosity measurements. The values of critical micelle concentration decreased and the composition of the micellar core tended to consist of PO segments mainly with increasing KCl concentration. The intrinsic viscosity and hydration of the micellar shell increased at the present of KCl. The effect of KSCN on structure of the Pluronic micelles was opposite to KCl. |
