摘要
研究了非离子表面活性剂NP-10在硝酸钠水溶液中形成的层状液晶的流变性。体系的频率扫描曲线随温度升高表现出3种不同的形式:低温时类似广义Maxwell模型;高温时的曲线形式还没有合适的方程来拟合;中等温度范围内表现出典型的非离子表面活性剂层状液晶的频率扫描曲线形式。用4元素的Burgers模型拟合了体系蠕变-回复实验的数据,线性相关系数都在0 9以上。
Rheological properties of lamellar liquid crystalline phase of nonionic surfactant NP-10 in NaNO_3 water solution was investigated.The frequency sweeping rheogram at low temperature is in agreement with a generalized Maxwell model,while no equation can fit the rheogram at high temperature.A typical frequency sweep rheogram of nonionic surfactant liquid crystal can be observed at a moderate temperature range.Creep-recovery experiment data was fitted by a four elements Burgers model,and the linearity correlation coefficient is always superior to 0.9.
