A Review on the Flammability Properties of Carbon-Based Polymeric Composites: State-of-the-Art and Future Trends

Abstract

Carbon based fillers have attracted a great deal of interest in polymer composites becauseof their ability to beneficially alter properties at low filler concentration, good interfacial bonding withpolymer, availability in different forms, etc. The property alteration of polymer composites makesthem 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 polymercomposites, 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 widevariety of carbon-based material addition (such as fullerene, CNTs, graphene, graphite, and so on) onreaction-to-fire of the polymer composites are reviewed and the focus is dedicated to biochar-basedreinforcements for use in flame retardant polymer composites. Additionally. the most widely usedflammability measuring techniques for polymeric composites are presented. Finally. the key factorsand different methods that are used for property enhancement are concluded and the scope for futurework is discussed.
