摘要
碳纳米管(CNTs)的添加可以增加聚氯乙烯(PVC)的强度和刚度,并提高其导电性能。为了提高PVC的适应性与稳定性,文章合成了不同比例的PVC/CNTs复合材料,并分析其拉伸强度、导热性能、导电性能和热稳定性能,以确定复合材料的最优CNTs含量。结果表明:随着CNTs质量分数的增加,PVC/CNTs复合材料的拉伸强度先升高后降低。加入CNTs后,复合材料的导热性能得到提高。当CNTs质量分数为2.0%时,PVC/CNTs复合材料的拉伸强度、导热性能、导电性能和热稳定性能较优。
The addition of carbon nanotubes(CNTs) can increase the strength and stiffness of polyvinyl chloride(PVC) while enhancing its electrical conductivity.In order to improve the adaptability and stability of PVC,the study synthesized PVC/CNTs composites with varying proportions and analyzed their tensile strength,thermal conductivity,electrical conductivity,and thermal stability to determine the optimal content of CNTs in the composite.The results show that with an increase in the mass fraction of CNTs,the tensile strength of PVC/CNTs composites first increase and then decrease.The introduction of CNTs improves the thermal conductivity of the composites.When the mass fraction of CNTs is 2.0%,the PVC/CNTs composite exhibits superior tensile strength,thermal conductivity,electrical conductivity,and thermal stability.
