| 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)复合材料。XRD分析表明:PPC/OMMT复合材料形成了插层型纳米复合结构。相对于纯PPC材料,纳米复合材料的拉伸性能和抗冲击性能得到了显著提高,但复合材料的断裂伸长率降低。当OMMT含量为6%时,PPC/OMMT纳米复合材料具有最优的力学性能和最高的玻璃化温度。

| Abstract: | Poly (propylene carbonate) (PPC)/organic montmorillonite (OMMT) composite were prepared by direct melt intercalation. XRD analysis indicated that PPC/OMMT nanocomposites with intercalated structure were prepared. Tensile strength and impact strength of the nanocomposites increased, while elongation at break decreased, compared with that of pure PPC. Moreover, Tg of the nanocomposites increased and the optimum mechanical and thermal properties occurred when OMMT content was 6%. |
