通过原位自组装法制备MWCNTs/PVA-co-PE复合材料,将此复合材料与纤维素酯共混后,利用热塑性聚合物熔融共混相分离法制备了MWCNTs/PVA-co-PE复合纳米纤维。通过SEM和TEM分析表征了MWCNTs/PVA-co-PE复合纳米纤维的形态、结构以及多壁碳纳米管在纳米纤维中的分布状态;研究了多壁碳纳米管添加量对MWCNTs/PVA-co-PE复合纳米纤维导电性能的影响。结果表明,当多壁碳纳米管的添加量大于6%时,MWCNTs/PVA-co-PE复合材料的表面电阻会显著下降;提高MWCNTs的添加量会使MWCNTs/PVA-co-PE复合纳米纤维的表面电阻稍微下降,但是效果不大,这可能是由于MWCNTs在纳米纤维内部不能形成良好的导电通道。
Abstract：The composites of multi-walled carbon nanotubes(MWCNTs)/poly(vinyl alcohol-co-ethylene)(PVA-co-PE) were prepared by in-situ polymerization.The composites were then blended with cellulose acetate butyrate(CAB),the MWCNTs/PVA-co-PE nanofibers were prepared by melt blending and phase separation of the(MWCNTs/PVA-co-PE)/CAB blends.The morphology of MWCNTs/PVA-co-PE nanofibers and the distribution of MWCNTs in PVA-co-PE were analyzed by SEM and TEM.The effect of mass fraction of MWCNTs on surface resistance of MWCNTs/PVA-co-PE nanofibers was studied.The results showed that when mass fraction of MWCNTs was 6wt%,the surface resistance of MWCNTs/PVA-co-PE composite decreased obviously.However,with the increase of mass fraction of MWCNTs,the surface resistance of MWCNTs/PVA-co-PE nanofiber decreased less obviously,which may be caused by discontinuous distribution of MWCNTs in PVA-co-PE.
