Study on thermal stability and combustible property of Poly(lactic acid)/Nickel molybdate nanorod composites

通过水热法合成形貌规整的钼酸镍(NiMo),并合成掺杂稀土Ce元素的钼酸铈镍(NiMoCe)纳米棒做对比研究。用聚苯乙烯(PS)增强聚乳酸(PLA)基体,聚乙二醇(PEG)用于PLA材料的增韧。熔融共混法制备PLA/PS/PEG/纳米棒复合材料,研究复合材料的热稳定性、燃烧性能和机械性能。结果表明,纳米棒可以有效提高材料的热稳定性、降低燃烧性能,PS和PEG在PLA基体中具有增强和增韧作用。

Nickel molybdate （NiMo） nanorods with uniformmorphorlogy were prepared by the hydrothermal technique, and nickel molybdates doped with Ce （NiMoCe） nanorods were syn- thesized for comparative research. Polystyrene （PS） was used for enhancing poly （laelie） acid （PLA）. Polyethylene glycol （PEG） was used as a toughening reagent. PLA/PS/PEG/ naorod composites were prepared. The thermal stability, com- bustible property and mechanical＂ property of PLA composites were investigated. The results showed that nanorods were use- ful to improve the thermal stability of PLA composites and de- crease combustible property, PS and PEG had enhancing and toughening effect.
