摘　　要：采用扫描电镜(SEM)、动态力学分析(DMA)、力学性能测试、动态流变分析等手段研究了基体极性和相容剂对磷酸盐玻璃(TFP)/聚丙烯(PP)复合体系相容性的影响。结果表明,当基体用聚丙烯接枝马来酸酐(PP-MAH)替换非极性的聚丙烯(PP)时,磷酸盐玻璃(TFP)粒子在基体中的分散尺寸由10μm减小为2μm,分散相对复合材料的复数黏度(η*)的影响更为明显;加入相容剂后,体系的黏度进一步增大,且基体的玻璃化转变温度向高温方向移动了5℃,复合材料的断裂伸长率近似线性增长。The effect of enhancing the polarity of matrix and adding compatibilizer on the compatibilization of polypropylene/phosphate glass（PP/TFP） composites was studied by scanning electron microscope（SEM）,dynamic mechanical analysis（DMA） and mechanical analysis etc.The experimental results show that the size of disperses TFP particles decreases from 10 μm to 2 μm and the complex viscosity increases more when PP-MAH replaces PP as the matrix,indicating that the interaction between TFP and PP-MAH is better than that between TFP and PP. The complex viscosity of the composites increases further when PAM15 is added as the compatibilizer.The glass transition temperature of matrix moves to high temperature by 5 ℃.The elongation at break of these composites increases linearly with increasing the content of PAM15.
