Abstract

Metal organic frameworks (MOFs) are a novel class of multidimensional nanoscale substances that exhibit highly controllable structures and possess large specific surface areas and porosities. In recent years, MOFs have garnered significant attention as flame retardants. This paper elucidates the construction method of MOFs-based flame retardant nanostructures and the flame retardant mechanism. Meanwhile, it provides a comprehensive review of recent advancements in utilizing pristine MOFs, MOFs composites incorporating phosphorus-nitrogen-based, carbon-based, silicon-based, and other materials, as well as MOFs-based multicomponent hybrids as flame retardant in polymeric materials. This study presents the modification of MOFs for their application as flame retardants in terms of both structure and chemical composition and outlines their flame retardant mechanisms and flame retardant efficiencies. The emphasis is placed on elucidating the flame retardant mechanism achieved through multi-component synergy. Finally, the paper summarizes the existing challenges as well as the prospects of MOFs-based flame retardants, with a view to providing guidance for the design of innovative flame retardant materials.

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
