Clarification of the details of the interface structure between liquids and solids is crucial for understanding the fundamental processes of physical functions. Herein, we investigate the structure of the interface between tetraglyme and graphite and propose a model for the interface structure based on the observation of frequency-modulation atomic force microscopy in liquids. The ordering and distorted adsorption of tetraglyme on graphite were observed. It is found that tetraglyme stably adsorbs on graphite. Density functional theory calculations supported the adsorption structure. In the liquid phase, there is a layered structure of the molecular distribution with an average distance of 0.60 nm between layers.
阐明液体和固体界面的细节结构对于理解物理功能的基本过程至关重要。在此，我们研究了四甘醇和石墨之间的界面结构，并基于液体中调频原子力显微镜的观察提出了一种界面结构模型。观察到四甘醇在石墨上的有序和扭曲吸附。结果发现，四甘醇在石墨上稳定吸附。密度泛函理论计算支持了吸附结构。在液相中，分子分布具有层状结构，层与层之间的平均距离为 0.60nm。
