摘　　要：采用熔融共混法制备了高密度聚乙烯(HDPE)/HDPE接枝马来酸酐(HDPE-g-MAH)/纳米碳酸钙(nano-CaCO3)复合材料,研究了HDPE-g-MAH用量对复合材料力学性能的影响,并利用透射电镜(TEM)分析了nano-CaCO3在HDPE基体中的分散性。结果表明:HDPE-g-MAH的加入可明显改善复合材料的力学性能,并且有助于强化nano-CaCO3在HDPE基体中的分散效果。HDPE/HDPE-g-MAH/nano-CaCO3 composite was prepared by melt blending HDPE with HDPE-g- MAH and nano-CaCO3. The effect of the content of HDPE-g-MAH on the mechanical properties of the composite was studied. The dispersion of the nano-CaCO3 in HDPE matrix was analyzed by TEM. The results show that the mechanical properties of the composite improve evidently by adding the HDPE-g-MAH, and the addition of the HDPE-g-MAH is beneficial to improve the dispersion of the nano-CaCO3 in HDPE matrix.
