研究了琥珀酸二 (2 -乙基己基 )酯磺酸钠 (AOT)与聚合物表面活性剂混合后在非极性溶剂中的聚集行为 .结果表明 ,随聚合物与 AOT摩尔比的增大 ,体系的 CMC逐渐增大 ,但该摩尔比大于 1∶ 1时 ,用水增溶法不能测出 CMC;研究了荧光探针 Ru(bpy) 2 + 3在该混合反胶团中的荧光行为 .随有机相含水量 W0 增大 ,对微极性敏感的荧光探针的最大发射波长 λmax逐渐红移 ,荧光强度 F则逐渐减弱 .随聚合物含量增大 ,混合体系表面活性剂极性基的水合过程在较小 W0 下完成
The aggregation behavior of AOT with a polymeric surfactant in apolar solvents was studied.The results showed that with the increase of molar ratio of AOT to AOT, , The CMC of the system gradually increased. However, the CMC could not be measured by water solubilization when the molar ratio was greater than 1: 1. The fluorescence of Ru (bpy) 2 + 3 in this mixed reverse micelle was studied. With the increase of the organic phase water content W0, the maximum emission wavelength λmax of the micropolar-sensitive fluorescent probe gradually red-shifted and the fluorescence intensity F decreased gradually.With the increase of the polymer content, the polar groups of the surfactant The hydration process is done at smaller W0
