咪唑类离子液体对四乙二醇月桂醚／水层状结构的影响

摘要

In this paper,the lamellar hybrid with ionic liquids doped in lyotropic liquid crystal formed by C12 E4 and water was realized by Small - Angle X - ray Scattering. According to the structural parameters of lamellar structures,the stacking of surfactant molecules will be in a looser manner when doping ionic liquids. The difference of amphiphilic nature between two used ionic liquids makes Bmim-PF6 tend to stay at the interface of polar/apolar section,whereas Bmim-BF4 molecules like to locate in water regions as well as in polar domains.%利用小角X射线散射技术，研究了咪唑类离子液体对C12 E4／水形成的层状结构的影响。结果表明，加入离子液体可使表面活性剂分子以一种更加松散的方式进行堆积；对于两种离子液体Bmim－PF6和Bmim－BF4，前者主要处于双亲分子的EO基团区域，而Bmim－BF4既可处于EO区域也可进于水层。
