doi:10.19491/j.issn.1001-9278.2021.06.020

Abstract

Abstract:

Metal organic frameworks （MOFs） have provided a new direction for the flame retardancy of polymer materials. Besides being used as flame retardants， MOFs can also be hybridized into organic and inorganic materials to achieve better flame?retardant properties. In this paper， the classification and synthetic methods of MOFs were briefly introduced， and the recent research progress in the flame retardancy of polymer materials was reviewed in terms of the aspects from the applications of modified and unmodified MOFs in polymers to their flame retardant mechanism. The application perspective was summarized and prospected.

Key words: metal organic framework material, flame retardant mechanism, multifunctional, organic?inorganic hybrid, mechanical property
