Metal-organic frameworks(MOFs)are a kind of unique inorganic-organic hybrid structural compounds,which are porous compounds formed by central metal ions(clusters)and organic ligands,and have a wide range of applications in adsorption,drug transport and flame retardant fields.The basic structure and classification of MOFs were briefly described,the latest research progress of MOFs as a single flame retardant in flame retardant polymer materials and in collaboration with other compounds for synergistic flame retardant polymer materials was reviewed,the flame retardant effect and flame retardant mechanism of different MOFs flame retardants in polymer composites were analyzed,and the flame retardant mechanism of MOFs flame retardants was summarized.Finally,the flame retardancy application of MOFs in polymer materials was prospected.
