论文摘要
本文介绍了使用石英调谐叉制成的悬挂纤维力探头的频率调制AFM如何为液态液接口提供局部测量。在详细介绍了力探针的制造和校准之后，我们提供了证据表明，该AFM适合在两个液体之间的界面上进行定量测量。测量值的可重复性允许在几个小时内监测聚二甲基硅氧烷 /水移动界面：观察到浸入聚二甲基硅氧烷中的水滴的蒸发，并测量其界面张力的演变。还观察到界面的变形。这些功能以及两个不混溶液体之间的界面的初步结果为界面操纵和研究复杂的流体流体界面铺平了道路。
This article describes how a frequency modulation AFM using a hanging fiber force probe made from a quartz tuning fork provides local measurements on liquid-liquid interfaces. After detailing the manufacture and calibration of the force probe, we provide evidence that this AFM is suitable for quantitative measurements at the interface between two liquids. The repeatability of the measurements allows a poly-dimethylsiloxane / water moving interface to be monitored over several hours : the evaporation of a water droplet immersed in poly-dimethylsiloxane is observed, and its interfacial tension evolution over time is measured. Deformation of the interface is also observed. These capabilities, and preliminary results on the interface between two immiscible liquids, pave the way for interface manipulation and study of complex fluid-fluid interfaces.
