摘　　要：以竹炭(BC)为填料,聚丙烯(PP)树脂为基体,采用熔融共混法制备了PP/BC复合材料,通过扫描电子显微镜、吸水率、显气孔率、力学性能和热稳定性进行综合分析,研究了BC含量对其导电性能的影响。结果表明,BC的引入可以显著降低PP/BC复合材料的体积电阻率,当BC含量大于30%(质量分数,下同)时,增长效果尤为明显。The bamboo charcoal(BC)-reinforced polypropylene composites were prepared by a melt-blending method,and the effect of BC content on the electrical conductivity of the composites was evaluated.The results indicated that the addition of BC reduced the volume resistivity of the composites significantly,and the electrical conductivity exhibited a higher growth rate especially with the addition of BC over 30 wt%.Moreover,the morphology,water absorption,apparent porosity,mechanical properties and thermal stability of the composites were also investigated.
