| 摘 要： | 通过静电纺丝法制备出多壁碳纳米管(MWCNTs)增强聚己内酯(PCL)超细复合纤维膜。用扫描电镜(SEM)、透射电镜(TEM)、拉曼光谱仪、差示扫描量热仪(DSC)和X射线衍射仪(XRD)对MWCNTs/PCL超细复合纤维进行表征,并进行了拉伸测试。结果表明,MWCNTs分散于PCL纤维中,MWCNTs的加入降低了PCL的结晶度。当PCL中MWCNTs的含量为0.5 wt%时,其结晶度最低,但此时MWCNTs/PCL超细复合纤维具有最好的力学性能。

| Abstract: | Multi-walled carbon nanotubes (MWCNTs) reinforced poly(ε-caprolactone) (PCL) ult rafine composite fibers were prepared by means of elect rospinning. Scanning electron microscopy (SEM) , transmission electron microscopy (TEM), Raman spect roscopy, differential scanning calorimeter (DSC) and X-ray diff raction (XRD) were used to characterize the electrospun ultrafine MWCNTs/PCL fibers and the mechanical properties of fibers were also tested. The results indicate that MWCNTs have been dispersed in PCL, which can reduce the crystallization of PCL. When the content of MWCNTs is 0. 5 wt% , elect rospun MWCNTs/PCL composite fibers have the best mechanical properties with the lowest crystallinity of PCL. |
