摘要:
以KNG-150石墨烯微片(GNPs)为导电填料,PP(聚丙烯)/HDPE(高密度聚乙烯)复合体系为基体材料,制备石墨烯微片/PP/HDPE导电复合材料,研究GNPs质量分数,PP/HDPE质量比对材料的正温度系数效应(PTC)强度和负温度系数效应(NTC)强度的影响. 结果表明:GNPs质量分数处在渗滤区间6%时,材料的PTC强度达到最大值;PP的加入可以有效地提高材料的PTC强度,同时还抑制了NTC效应;当PP/HDPE质量比为3∶7时,效果最佳,此时PTC强度为5.58,NTC强度仅为0.25.
Abstract:
In this paper, the KNG-150 graphene nanoplatelets(GNPs)was used as the conductive filler, and the polypropylene(PP)/high density polyethylene(HDPE)composite system were used as the matrix material, produced the GNPs/PP/HDPE conductive composite, the effect of the GNPs contents and the proportion of PP/HDPE on the intensity PTC and NTC are invented. The result showed that the intensity PTC of this composite reach the max when the content of the GNPs was 6%; The PTC intensity efficiently enhanced and the NTC intensity was inhibited as the PP was added into the composite. When the proportion of m(PP)∶m(HDPE)was 3∶7, this composite reached the best result, the PTC and NTC intensity was 5.58 and 0.25.
