摘要(Abstract)：

采用超声波辅助溶液共混的方式制备聚乙烯醇/多壁碳纳米管(PVA/MWCNT)复合溶液,并将该溶液与聚氧化乙烯(PEO)溶液共混,利用静电纺丝技术制备PVA/PEO/MWCNTs复合超细纤维。运用扫描电子显微镜(SEM)、X-射线衍射仪(XRD)、示差扫描量热仪(DSC)方法对不同MWCNTs含量的PVA/PEO/MWCNTs复合纤维的微观形貌、结构和热性能进行了观察分析。结果表明:随着MWCNTs含量的增加,纤维直径显著变细,MWCNTs的加入降低了纤维的结晶性,纤维的热稳定性有所提高。
In this paper,the polyvinyl alcohol/multi-walled carbon nanotubes(PVA/MWCNTs) complex solution was prepared by ultrasonic solution mixing methods,then this solution was mixed with polyethylene oxide(PEO),and the PVA/PEO/MWCNTs/ultra-fine composite fiber was obtained through electrospinning technique.The microstructure and heat properties of samples with different contents of MWCNTs were analyzed by scanning electron microscopy(SEM),X-ray diffraction(XRD),differential scanning calorimeter(DSC).The results indicated that the diameter of fiber got markedly thinner with increase of MWCNTs,the crystallinity of fiber reduced because of addition of MWCNTs.Furthermore,the thermal stability of composite fiber had improved some.
