| 摘 要： | 以聚丙烯（PP）为基体，以弹性体（POE、TPU）和纳米SiO2为改性剂，采用熔融共混法制备了PP／弹性体／纳米SiO2复合材料，研究了材料的力学性能、动态力学性能、结晶性能与流变性能。结果表明，弹性体和纳米粒子的加入具有明显的协同增韧效应；弹性体和纳米SiO2促进PP的结晶，TPU和纳米SiO2有更好的结晶成核作用；弹性体和纳米粒子使复合材料的模量、复合粘度增大。 |

| Abstract: | Polypropylene/elastomer/nano-silica composites were prepared by melt-blending process. Mechanic, dynamic mechanic, crystallization and rheological properties of composites were studied. The results showed that elastomer and nano-silica make significantly synergistic toughing effect on PP. Elastomer and nano-silica could promote the crystallization of PP,the heterogeneous nucleation effect of TPU and nano-silica were more obvious. The introduction of elastomer and nano-sili ca increased the modulus and viscosity of PP composites. |
