A series of water soluble, surface‐active ionic liquids (SAILs), namely, 1‐alkyl‐3‐methyl imidazolium chlorides ([Cn‐mim]Cl) and their mixtures with palmitic acid (PA) are investigated in Langmuir monolayers and Langmuir–Blodgett films. It is inferred from the surface pressure‐area isotherms that C16‐mim‐IL mixes non‐ideally with PA and stabilizes the binary mixed films. In addition, the residence of mim‐IL at the water surface is enhanced as a function of the increasing alkyl side chain length. Generally, the compressional moduli values decrease upon increasing the content of the mim‐ILs over a wide range of compositions. Furthermore, film relaxation measurements indicate that the IL component is selectively excluded from the mixed films upon achieving a certain target pressure. Brewster angle microscope images demonstrate minimal changes on the PA domains in the presence of either C4‐ and C8‐mim‐ILs, whereas presence of the hexadecyl counterpart results in the formation of condensed sheets. Atomic force microscopy imaging of deposited films show the formation of propeller‐like aggregates when C8‐ or C16‐mim‐IL is present in the mixed films.

混合单分子层中表面活性离子液体和棕榈酸的形态和相互作用特征。
在Langmuir单层膜中研究了一系列水溶性表面活性离子液体（SAIL），即1-烷基-3-甲基咪唑鎓氯化物（[C n - mim ] Cl）及其与棕榈酸（PA）的混合物。朗格米尔–布洛杰特电影。从表面压力-面积等温线可以推断出，C 16 - mim -IL与PA非理想地混合，并稳定了二元混合膜。此外，随着烷基侧链长度的增加，mim- IL在水表面的滞留性也得到增强。通常，压缩模量值随着mim含量的增加而降低‐IL组成范围广泛。此外，膜松弛测量表明，在达到一定目标压力时，IL组分被选择性地从混合膜中排除。布儒斯特角显微镜图像表明在任一C的存在对PA域最小的变化4 -和C 8 - MIM -ILs，而在冷凝片的形成十六烷基对应物的存在导致。沉积的膜的原子力显微镜成像显示的形成当C螺旋桨状的聚集体8 -或C 16 - MIM -IL存在于混合膜。
