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。
MWCNTs / PVA-co-PE composites were prepared by in-situ self-assembly method. After blending the composites with cellulose esters, MWCNTs / PVA-co-PE composite nanofibers were prepared by melt blending thermoplastic phase . The morphology and structure of the MWCNTs / PVA-co-PE composite nanofibers and the distribution of MWCNTs in the nanofibers were characterized by SEM and TEM. The effects of MWCNTs / PVA-co -PE composite nanofibers. The results showed that the surface resistance of MWCNTs / PVA-co-PE composites decreased significantly when the MWCNTs content was more than 6%. Increasing the amount of MWCNTs added to MWCNTs / PVA-co-PE composite nanofibers The surface resistance of the nanofibers decreases slightly, but the effect is not very good. This may be because the MWCNTs can not form good conductive channels inside the nanofibers.
