Tailoring the polymer-metal interface is crucial for advanced material design. Vacuum deposition methods for metal layer coating are widely used in industry and research. They allow for installing a variety of nanostructures, often making use of the selective interaction of the metal atoms with the underlying polymer thin film. The polymer thin film may eventually be nanostructured, too, in order to create a hierarchy in length scales. Grazing incidence X-ray scattering is an advanced method to characterize and investigate polymer-metal interfaces. Being non-destructive and yielding statistically relevant results, it allows for deducing the detailed polymer-metal interaction. We review the use of grazing incidence X-ray scattering to elucidate the polymer-metal interface, making use of the modern synchrotron radiation facilities, allowing for very local studies via in situ (so-called "stop-sputter") experiments as well as studies observing the nanostructured metal nanoparticle layer growth in real time.
定制聚合物-金属界面对于先进材料设计至关重要。用于金属层涂层的真空沉积方法在工业和研究中广泛使用。它们能够安装各种纳米结构，通常利用金属原子与底层聚合物薄膜的选择性相互作用。聚合物薄膜最终也可能被纳米结构化，以便在长度尺度上形成层次结构。掠入射X射线散射是表征和研究聚合物-金属界面的一种先进方法。由于其无损性且能产生具有统计相关性的结果，它有助于推断聚合物与金属之间的详细相互作用。我们回顾了利用掠入射X射线散射来阐明聚合物-金属界面的情况，利用现代同步辐射设施，通过原位（所谓的“停止溅射”）实验进行非常局部的研究，以及实时观察纳米结构化金属纳米颗粒层生长的研究。
