摘　　要：采用熔融共混法制备了聚丙烯(PP)/纳米碳酸钙(nano-CaCO3)复合材料,研究了nano-CaCO3表面改性前后对复合材料力学性能的影响,利用扫描电镜(SEM)分析了nano-CaCO3表面改性前后在PP基体中的分散性。结果表明:加入量较小时,nano-CaCO3表面改性与否对复合材料的力学性能和在PP基体中的分散性基本没有影响;加入量较大时,表面改性nano-CaCO3使复合材料具有更好的力学性能,并且在PP基体中的分散性及其与PP基体间的界面黏结性也更好。PP/nano-CaCO3 composite was prepared by melt blending PP with nano-CaCO3. The effect of the nano-CaCO3 before and after modification on mechanical property of the PP/nano-CaCO3 composite was studied. The dispersion of the nano-CaCOz before and after modification in PP matrix was analyzed by SEM. The results show that the mechanical property of the PP/nano- CaCO3 composite with the treated or untreated nano-CaCOa and the dispersion of the treated or untreated nano-CaCO3 in PP matrix exhibited slight difference at low Ioadings. At high Ioadings, the mechanical property of the PP/nano-CaCO3 composite with the treated nano-CaCO3 became better than that of the PP/nano-CaCO3 composite with the untreated nano-CaCO3; the dispersion of the treated nano-CaCO3 in PP matrix and interfacial adhesion between them also became better than those of the untreated nano-CaCO3 in PP matrix.
