Flame-Retardant Modification of Layered Double Hydroxides from Biomass Resources for Polylactic Acid.

ABSTRACT: Layered double hydroxides (LDHs) have attracted more and more attention in the field of flame retardants because of their halogen-free, nontoxic, and excellent smoke suppression properties. However, due to the easy agglomeration and poor compatibility with the polymer matrix, its flame-retardant efficiency was reduced. In this study, a novel flame retardant containing phytic acid-modified LDH (PA-LDH) was prepared for polylactic acid (PLA). The microstructure and properties of PA-LDH were analyzed, and the flame retardancy of PLA composites based on the PA-LDH hybrid system was discussed. The research results indicated that PA-LDH exhibited better dispersion than LDH in PLA, which was favorable for the improvement of its flame retardancy. The PLA composites containing 25 wt % PA-LDH (11.02
