研究了离子液体对水/丁二酸二（2-乙基己基）酯磺酸钠（AOT）/异辛烷微乳液温度诱导逾渗的影响。微乳液的几个性质，包括渗流温度阈值（Tp），粘度，和液滴尺寸被用来证明的IL的结构对渗流现象的影响。加入IL后，微乳液出现明显的渗滤现象，且微乳液的Tpof随IL浓度的增加而增加。此外，Tp受咪唑阳离子的烷基侧链长度的影响很大，并随着链长的增加而增加。离子液体阴离子对Tp的影响较小，这是由于离子液体中表面活性剂的头部基团对电荷的排斥作用。此外，微乳液的粘度和液滴尺寸随着离子液体的添加而降低，并且观察到的降低与Tp的增加大致相关。这些结果也证实了离子液体对微乳液逾渗现象的影响。
The effect of ionic liquids (ILs) on temperature-induced percolation of water/sodium bis-(2-ethylhexyl) sulfosuccinate (AOT)/isooctane microemulsions was investigated. Several properties of microemulsions, including percolation temperature threshold (Tp), viscosity, and droplet size were used to demonstrate the effect of the structure of ILs on percolation phenomena. Percolation phenomena of microemulsions were clearly observed after the addition of IL, and the Tpof microemulsions increased with increases in the ILs concentration. In addition, Tpwas greatly affected by the alkyl side-chain length of imidazolium cation and increased with increases in chain length. However, Tpwas slightly affected by the ILs anions due to the charge exclusion caused by the head group of surfactant. Additionally, the viscosity and droplet size of microemulsions decreased with the addition of ILs, and the observed decrease correlated roughly with an increase in Tp. These results also confirm the influence of ILs on percolation phenomena of the microemulsions.
