Metal-organic frameworks (MOFs) are considered as the potential flame retardant substances with proper flame retardancy. Despite their unique structural features and adjustable chemical composition, MOFs alone could hardly meet all the requirements of the commercial flame retardant applications. Recently, co-application of MOFs and inorganic or organic additives has been introduced as a novel approach to obtaining highly efficient flame retardant polymer nanocomposites. The synergistic effect of these additives can resolve the limitations of MOFs. This review addresses the flame retardant mechanism of MOFs, and their composites application and new prospects of MOFs to promote fire safety in polymers. This review focuses on the latest studies on MOFs as efficient flame retardant additives for diverse polymer composites and their impact on thermal stability and flame retardancy.

金属有机骨架（MOF）被认为是具有适当阻燃性的潜在阻燃物质。尽管MOF具有独特的结构特征和可调节的化学成分，但仅靠MOF很难满足商业阻燃应用的所有要求。近来，已经引入了MOF与无机或有机添加剂的共同应用作为获得高效阻燃聚合物纳米复合材料的新方法。这些添加剂的协同作用可以解决MOF的局限性。本文综述了MOFs的阻燃机理及其在复合材料中的应用，以及MOFs在促进聚合物防火方面的新前景。
