Layered double hydroxides (LDH) has wide applications as non-toxic and halogen-free flame retardant for
various resins and highly efficient thermal stabilizer for halogen-containing polymers. This review will discuss some public
patents and relevant papers on the flame retardancy and the thermal stability of LDH/polymer composites when the
LDHs with different chemical compositions are used as the additive in the polymer matrix. We have summarized these related
LDHs in two tables: one for flame retardant and the other for thermal stabilizer.
