摘要
无机电解质 KCl的加入促使 Pluroinc嵌段共聚物 F10 8和 P94的临界胶束浓度 Ccm c减小 ,胶束内核的 PO百分含量增加 ,外壳整体水化程度增大 ,反映为胶束的特性粘度 [η]值增大。而 KSCN的影响则相反。
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.
