Metal-Organic Frameworks (MOFs) have emerged as advanced porous crystalline materials due to their highly ordered structures, ultra-high surface areas, fine-tunable pore sizes, and massive chemical diversity. These features, arising from the coordination between an almost unlimited number of metal ions/clusters and organic linkers, have resulted in significant interest in MOFs for applications in gas storage, catalysis, sensing, energy, and biomedicine. Beyond their stand-alone properties and applications, recent research has increasingly explored the integration of MOFs with other substrates, particularly electrodes, polymeric thin films, and glass surfaces, to create synergistic effects that enhance material performance and broaden application potential. Coating MOFs onto these substrates can yield significant benefits, including, but not limited to, improved sensitivity and selectivity in electrochemical sensors, enhanced mechanical and separation properties in membranes, and multifunctional coatings for optical and environmental applications. This review provides a comprehensive and up-to-date summary of recent advances (primarily from the past 3-5 years) in MOF coating techniques, including layer-by-layer assembly, in situ growth, and electrochemical deposition. This is followed by a discussion of the representative applications arising from MOF-substrate coating and an outline of key challenges and future directions in this rapidly evolving field. This article aims to serve as a focused reference point for researchers interested in both fundamental strategies and applied developments in MOF surface coatings.
金属有机框架材料（MOFs）因其高度有序的结构、超高的比表面积、可精细调节的孔径以及丰富的化学多样性，已成为先进的多孔晶体材料。这些特性源于几乎无限数量的金属离子/簇与有机连接体之间的配位作用，使得MOFs在气体存储、催化、传感、能源和生物医学等应用领域引发了广泛关注。除了其自身的性质和应用外，最近的研究越来越多地探索将MOFs与其他基底，特别是电极、聚合物薄膜和玻璃表面相结合，以产生协同效应，从而提高材料性能并拓宽应用潜力。将MOFs涂覆在这些基底上可带来诸多显著益处，包括但不限于提高电化学传感器的灵敏度和选择性、增强膜的机械性能和分离性能，以及用于光学和环境应用的多功能涂层。本综述全面且最新地总结了MOF涂覆技术（主要是过去3至5年）的最新进展，包括逐层组装、原位生长和电化学沉积。随后讨论了MOF - 基底涂层的代表性应用，并概述了这一快速发展领域的关键挑战和未来方向。本文旨在为对MOF表面涂层的基础策略和应用开发感兴趣的研究人员提供一个重点参考。
