Polymer matrix is vulnerable to fire hazards and needs to add flame retardants to enhance its performance and make its application scenarios more extensive. At this stage, it is more necessary to add multiple flame-retardant elements and build a multi-component synergistic system. Metal organic frameworks (MOFs) have been studied for nearly three decades since their introduction. MOFs are known for their structural advantages but have only been applied to flame-retardant polymers for a relatively short period of time. In this paper, we review the development of MOFs utilized as flame retardants and analyze the flame-retardant mechanisms in the gas phase and condensed phase from the original MOF materials, modified MOF composites, and MOF-derived composites as flame retardants, respectively. The effects of carbon-based materials, phosphorus-based materials, nitrogen-based materials, and biomass on the flame-retardant properties of polymers are discussed in the context of MOFs. The construction of MOF multi-structured flame retardants is also introduced, and a variety of MOF-based flame retardants with different morphologies are shown to broaden the ideas for subsequent research.
聚合物基体易受火灾危害，需要添加阻燃剂以提高其性能并使其应用场景更加广泛。现阶段，更有必要添加多种阻燃元素并构建多组分协同体系。金属有机框架材料（MOFs）自问世以来已被研究了近三十年。MOFs以其结构优势而闻名，但应用于阻燃聚合物的时间相对较短。在本文中，我们综述了用作阻燃剂的MOFs的发展，并分别从原始MOF材料、改性MOF复合材料以及MOF衍生复合材料作为阻燃剂的角度，分析了其在气相和凝聚相中的阻燃机理。在MOFs的背景下，讨论了碳基材料、磷基材料、氮基材料和生物质对聚合物阻燃性能的影响。还介绍了MOF多结构阻燃剂的构建，并展示了各种不同形态的基于MOF的阻燃剂，为后续研究拓宽思路。
