Use of Layered Double Hydroxides as Polymer Fire-Retardant Additives: Advantages and Challenges
Contribution to Book
Fire and Polymers V : Materials and Concepts for Fire Retardancy
Layered Double Hydroxides (LHDs) have been identified as a promising new additive class for generating polymer nanocomposites with enhanced thermal stability and improved flammability properties. An advantage of these materials over structurally similar smectite clays is the ability to tune physical and chemical properties via simple synthetic strategies that can modify the metal hydroxide layer and/or the identity of the charge-balancing interlayer anion. Recent advances in development of LDHs for polymer fire retardancy applications are reviewed here and a discussion of future challenges is provided.
