Adhesion is a key issue for researchers of various fields, it is therefore of uppermost importance to understand the parameters that are involved. Commonly, only surface parameters are employed to determine the adhesive forces between materials. Yet, van der Waals forces act not only between atoms in the vicinity of the surface, but also between atoms in the bulk material. In this review, we describe the principles of van der Waals interactions and outline experimental and theoretical studies investigating the influence of the subsurface material on adhesion. In addition, we present a collection of data indicating that silicon wafers with native oxide layers are a good model substrate to study van der Waals interactions with coated materials.
粘附是各个领域研究人员关注的一个关键问题，因此，理解涉及的参数至关重要。通常，仅使用表面参数来确定材料之间的粘附力。然而，范德华力不仅作用于表面附近的原子之间，而且还作用于体材料中的原子之间。在这篇综述中，我们描述了范德华相互作用的原理，并概述了研究次表面材料对粘附影响的实验和理论研究。此外，我们还提供了一组数据，表明具有本征氧化层的硅片是研究与涂层材料的范德华相互作用的良好模型衬底。
