利用小角X射线散射和小幅振荡实验研究了Brij 97/H2O/ bmim-BF4 和 Brij 97/H2O / bmim-PF6 体系层状液晶的微观结构和动态流变性质.结果表明两层状液晶体系分别表现gel-like 和fluid-like 的动态流变行为,而且 bmim-PF6 和 bmim-BF4增溶在液晶结构的不同位置.

Microstructure and dynamic rheological properties of lamellar liquid crystals formed in Brij 97/water/ bmim-BF4 and Brij 97/water/ bmim-PF6 systems were investigated by means of SAXS and small amplitude oscillatory shear measurements. It is shown that two systems exhibit gel-like and fluid-like rheograms respectively, along with the different locations of bmim-PF6 and bmim-BF4 penetrating through the lamellar phase.
