The fluorescence measurements of tetraethylene glycol dodecyl ether (C12E4) and triblock polymer (Pluronic P103), poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide), (EO)17(PO)60(EO)17, binary mixtures have been performed over the whole mixing range in the temperature range of 20-40 degrees C. The results have been evaluated by computing various micellar parameters and excimer formation. It has been concluded that mixed micelle formation takes place due to unfavorable mixing at lower temperature range, and the magnitude of which decreases with the increase in temperature up to 40 degrees C. The reduction in the unfavorable mixing has been attributed to the dehydration of P103 micelles with the increase in temperature.
在20至40摄氏度的温度范围内，对十二烷基四乙二醇醚（C12E4）与三嵌段聚合物（普朗尼克P103），即聚环氧乙烷-聚环氧丙烷-聚环氧乙烷，（EO）17（PO）60（EO）17的二元混合物进行了荧光测量。通过计算各种胶束参数和激基缔合物的形成对结果进行了评估。得出的结论是，在较低温度范围内，由于混合不利会形成混合胶束，并且随着温度升高至40摄氏度，其数量会减少。不利混合的减少归因于随着温度升高P103胶束的脱水。
