“…It has a hollow sphere structure, which is usually composed of six-membered rings at a number ranging from five to seven. The free radical trapping effect of fullerenes can improve the flame retardancy of materials and has attracted the attention of many researchers [95]. In addition, other types of carbon nanomaterials, such as expandable graphite and carbon black, have been a source of research as well.…”

In recent years, nanocarbon materials have attracted the interest of researchers due to their excellent properties. Nanocarbon-based flame retardant polymer composites have enhanced thermal stability and mechanical properties compared with traditional flame retardant composites. In this article, the unique structural features of nanocarbon-based materials and their use in flame retardant polymeric materials are initially introduced. Afterwards, the flame retardant mechanism of nanocarbon materials is described. The main discussions include material components such as graphene, carbon nanotubes, fullerene (in preparing resins), elastomers, plastics, foams, fabrics, and film–matrix materials. Furthermore, the flame retardant properties of carbon nanomaterials and their modified products are summarized. Carbon nanomaterials not only play the role of a flame retardant in composites, but also play an important role in many aspects such as mechanical reinforcement. Finally, the opportunities and challenges for future development of carbon nanomaterials in flame-retardant polymeric materials are briefly discussed.

“…In recent years, free‐radical scavengers such as fullerene (C 60 ) 24,25 and hindered amine 26–28 were proved to be good synergists in improving the flame retardancy of IFR. Our previous works 29–31 revealed that a very small amount of N ‐alkoxy hindered amines (NOR) efficiently improved the flame retardancy of PP by free‐radical quenching.…”

High‐efficiency macromolecular intumescent flame retardant (MIFR) is urgently demanded but of great challenge. In this work, a novel N‐alkoxyamine‐containing MIFR‐decorated zirconium phosphate (ZrP) nanosheet (denoted as RQMIFR‐ZrP) was synthesized and combined with ammonium polyphosphate (APP) to endowed polypropylene (PP) with excellent flame retardancy. With the addition of 6.3 wt% RQMIFR‐ZrP and 18.7 wt% APP, PP classed a UL‐94 V‐0 rating with a high LOI value of 39.5%. Moreover, the peak heat release rate, the total heat release, the peak of CO production, and the peak of CO2 production of PP/RQMIFR‐ZrP/APP decreased by 94.0%, 83.2%, 91.3%, and 91.7%, respectively. It revealed that RQMIFR‐ZrP not only generated nitroxyl radicals (NO•) to suppress the chain degradation of PP but also promoted to form high‐quality intumescent char layers with the catalytic carbonization and layered barrier effect of ZrP nanosheet, which effectively prevented PP from burning. This work provides a new approach to preparing high‐performance flame‐retardant polymer.

“…Fullerene, informally called buckyball, is an allotrope of carbon. The fullerene family contain C 60 , C 70 , C 78 , C 82 , C 84 , C 90 , C 96 , and so on, and, among these, the most important and widely used member in polymer composites is C 60 , which is spherically shaped carbonaceous nanomaterial having excellent medical benefits and it is also an antioxidant [ 8 ]. C60 is called radical sponge i.e., C60 shows high reactivity towards free radicals and can trap more than 34 free radicals during the combustion of polymer [ 9 ].…”

Carbon based fillers have attracted a great deal of interest in polymer composites because of their ability to beneficially alter properties at low filler concentration, good interfacial bonding with polymer, availability in different forms, etc. The property alteration of polymer composites makes them versatile for applications in various fields, such as constructions, microelectronics, biomedical, and so on. Devastations due to building fire stress the importance of flame-retardant polymer composites, since they are directly related to human life conservation and safety. Thus, in this review, the significance of carbon-based flame-retardants for polymers is introduced. The effects of a wide variety of carbon-based material addition (such as fullerene, CNTs, graphene, graphite, and so on) on reaction-to-fire of the polymer composites are reviewed and the focus is dedicated to biochar-based reinforcements for use in flame retardant polymer composites. Additionally, the most widely used flammability measuring techniques for polymeric composites are presented. Finally, the key factors and different methods that are used for property enhancement are concluded and the scope for future work is discussed.
