| Popis: | NiAl layered double hydroxide doped Zn with dodecylbenzenesulfonate anions (NiZnAl) was prepared by one-step coprecipitation method. Hexaphenoxycyclotriphosphazene (HPCP) is a cyclophosphazene derivative. NiZnAl first combined with HPCP were used to prepare polylactic acid (PLA) composites. Effect of NiZnAl and HPCP on flame retardancy of PLA was investigated. NiZnAl exhibited nano-dispersion in PLA composites, and its layers were intercalated by PLA chains. Limiting oxygen index value of all the PLA composites with incorporation of HPCP and NiZnAl increased, and UL-94 tests passed V0 ratings. With the presence of NiZnAl in PLA/HPCP composites, the amount of graphite crystalline carbon after burning was increased. High peak of heat release rate, heat release capacity, and the total heat release had a big reduction. The amount of char residue was increased apparently. The thermal degradation process was delayed. The summary results suggested that NiZnAl and HPCP had a good synergistic flame retardant effect in PLA. POLYM.
