The interaction between two immiscible materials is related to the number of contacts per unit area formed by the two materials. For practical reasons, this information is often parametrized by the interfacial free energy, which is commonly derived via rather cumbersome approaches, where properties of the interface are described by combining surface parameters of the single materials. These combining rules, however, neglect any effect that geometry might have on the strength of the interfacial interaction. In this Article, we demonstrate that the number of contacts at the interface between a thin polymer coating and its supporting substrate is altered upon confinement at the nanoscale level. We show that explicitly considering the effect of nanoconfinement on the interfacial potential allows a quantitative prediction of how sample geometry affects the number of contacts formed at the interface between two materials.

通过纳米约束技术来增强界面相互作用的强度

两种不混溶材料之间的相互作用与两种材料形成的每单位面积的接触数有关。出于实际原因，该信息通常由界面自由能参数化，通常通过相当繁琐的方法得出界面自由能，其中界面性质是通过组合单一材料的表面参数来描述的。这些合并规则但是，忽略了几何形状可能对界面相互作用的强度产生的任何影响。在本文中，我们证明了在纳米级水平上，薄聚合物涂层与其支撑基材之间的界面处的接触数会发生变化。我们表明，明确考虑纳米约束作用对界面电位的影响，可以定量预测样品的几何形状如何影响在两种材料之间的界面处形成的接触数。
