| 摘 要： | 通过熔融插层法制备了聚碳酸亚丙酯(PPC)/有机蒙脱土(OMMT)纳米复合材料。研究了OMMT对PPC/OM-MT纳米复合材料热氧老化的影响。结果表明,老化以后复合材料的拉伸强度以及断裂伸长率的保留率均高于纯PPC。加入OMMT后,复合材料的热老化性能明显改善。

| Abstract: | Poly(propylene carbonate) (PPC)/organophilic montmorillonite (OMMT) nanocomposites were prepared by direct melt intercalation. Effect of OMMT on thermal oxidative aging of PPC/OMMT nanocomposites was investigated. The results showed that the reserved values of tensile strength and elongation at break of PPC/OMMT nanocomposites were higher than that of pure PPC after thermal oxidative aging. The heat-aging properties of PPC were obviously improved by adding OMMT. |
