摘　　要：以环氧功能化聚丙烯(PP-g-GMA)作为纳米SiO2/PP复合材料的增容剂,研究了PP-g-GMA对复合材料力学、结晶和流变性能的影响。研究结果表明,PP-g-GMA的加入使PP复合材料的拉伸强度、冲击强度提高;使PP的结晶峰温明显提高,使复合材料的储能模量和复合黏度均明显高于纯PP。Epoxy functionalized PP （PP-g-GMA） was added into nano-SiO2/PP composites as compatibilizer, and the effects of PP-g-GMA on mechanic, crystallization and rheology properties of composites were studied. The results showed that the addition of PP-g-GMA can improve the mechanic properties of nano-SiO2/PP composites, facilitate filler induced crystallization of PP, raised crystallization temperature and increased the modulus and viscosity of PP.
