Abstract
Abstract Layered double hydroxides (LDHs) have wide application as a promising flame retardant and highly efficient thermal stabilizer for various polymer resins. In this chapter, we summarize the most recent progress in the area of flame-retardant polymer/LDH nanocomposites, in order to outline the potential and to promote further developments in this field. Here we discuss the techniques and indices (e.g., thermogravimetric analysis, microscale combustion calorimeter, limiting oxygen index, cone calorimetry, and UL-94) for evaluating the thermal stability and flame-retardant properties of polymer nanocomposites. The effect of inorganic and organic LDH composition, the synergistic effect with other thermal stabilizers and fire retardants, and the corresponding thermal stability and flame-retardant mechanisms of LDHs are reviewed systematically.
