用偏光显微镜和RS75控制应力流变仪研究了LAS/AEO-9/肥皂/水拟三元体系的相行为.发现在靠近LAS/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/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层状相液晶过渡.在偏光显微镜下,观察到了层状相液晶和六角相液晶的偏光织构,并得到流变性能研究结果的印证.

Phase behavior and rheology property of LAS/AEO-9/Soap/H_2O pseudo-ternary system was studied with polarizing microscope and RS75 rheometer.The results showed that only lamellar phase could be observed on the side of the LAS/H_2O of the phase diagram.On the side of the AEO-9/H_2O,the changes of phases of the surfactant solution were very typical.With the increase of surfactant concentration,the phase in the solution transformed from micelle solution to hexagonal phase liquid crystal and lamellar phase liquid crystal gradually.The polarized patterns of lamellar phase liquid crystal and hexagonal phase liquid crystal had been observed under polarizing microscope.The results of rheology property study confirmed the phase behavior observation.
