| 摘 要： | 用偏光显微镜和RS75控制应力流变仪研究了LAS(直链烷基苯磺酸钠)/AEO-9(脂肪醇聚氧乙烯醚)/乙二醇/水的拟三元体系的相行为.发现在靠近LAS/乙二醇/水一侧整个液晶区只出现层状相液晶相、无六角相液晶相;而在靠近AEO-9/乙二醇/水一侧的相行为变化比较典型,随着表面活性剂浓度增大,由胶束溶液逐渐向六角相液晶和...

| Abstract: | The phase behavior and rheological property of LAS/AEO-9/C2H6O2/H2O were studied by the polarizing microscope and RS75 rheometer.The results showed that only lamellar phase could be observed on the side of the phase diagram of the LAS/C2H6O2/H2O system.With respect to the AEO-9/C2H6O2/H2O system,the phase changes were very typical.With an increasing surfactant concentration,the phase in the solution gradually changed from a micellar solution to a hexangular phase and lamellar phase.The optical textures of l... |
