Swelling layered clay minerals form an important sub-group of the phyllosilicate family. They are characterized by their ability to expand or contract in the presence or absence of water. This property makes them useful for a variety of applications, ranging from environmental technologies to heterogeneous catalysis, and including pharmaceutical and industrial applications. Solid State Nuclear Magnetic Resonance (SS-NMR) has been extensively applied in the characterization of these materials, providing useful information on their dynamics and structure that is inaccessible using other characterization methods such as X-ray diffraction. In this review, we present the key contributions of SS-NMR to the understanding of the mechanisms that govern some of the main applications associated to swelling clay minerals. The article is divided in two parts. The first part presents SS-NMR conventional applications to layered clay minerals, while the second part comprises an in-depth review of the information that SS-NMR can provide about the different properties of swelling layered clay minerals.

膨胀层状粘土矿物形成了页硅酸盐家族的一个重要亚群。它们的特点是在有水或无水的情况下能够膨胀或收缩。这种特性使它们可用于各种应用，从环境技术到多相催化，包括制药和工业应用。固态核磁共振 (SS-NMR) 已广泛应用于这些材料的表征，提供有关其动力学和结构的有用信息，而这些信息是使用其他表征方法（如 X 射线衍射）无法获得的。在这篇综述中，我们介绍了 SS-NMR 对理解控制与膨胀粘土矿物相关的一些主要应用的机制的关键贡献。文章分为两部分。
