摘　　要：研究了1-丁基-3-甲基咪唑十二烷基硫酸盐([bmim][DS])和1-丁基-3-甲基咪唑二(2-乙基己基)磺基琥珀酸酯盐([bmin][AOT]两种表面活性离子液体在正庚烷/水界面的动态界面张力和膨胀特性。比较了[bmim][DS]或[bmin][AOT]和传统表面活性剂十二烷基硫酸钠(SDS)或二(2-乙基己基)磺基琥珀酸酯钠(Na[AOT])之间的膨胀弹性,并且考察了1-丁基-3-甲基咪唑阳离子之间静电相互作用对界面膜特性的影响。另外,通过对比[bmim][DS]和[bmim][AOT]在不同浓度下的膨胀弹性,验证了烷基链数量的改变对界面膨胀流变行为的影响。The dynamic interfacial tension and dilational properties of 1-butyl-3-methylimidazolium dodecyl sulfate（ [bmim][DS]） and 1-butyl-3-methylimidazolium di（ 2-ethylhexyl） sulfosuccinate（ [bmim][AOT]） at n-heptane/water interface were studied. The dilational elasticity of [bmim][DS] or [bmim][AOT]was compared with traditional surfactants（ SDS or Na[AOT]）. The influence of electrostatic interaction of 1-butyl-3-methylimidazolium cations on the properties of interfacial film was investigated. In addition,by comparing the dilational elasticity at different concentrations of [bmim][DS] and [bmim][AOT],we verified the effects of the change in the number of alkyl chains on the interfacial dilational rheological behavior.
