摘要:
通过共挤出技术制备了高力学强度的聚乙烯/多壁碳纳米管(PE/MWCNTs)复合纤维。为了提高MWCNTs在PE纤维基体中的分散性,对MWCNTs进行了石蜡的包覆处理。利用红外光谱仪、光学显微镜、扫描电子显微镜、透射电子显微镜、拉曼光谱、电子万能试验机等研究了MWCNTs的引入对PE纤维性能的影响。结果表明,制备的复合纤维具有连续、均匀的结构。在普通的PE/MWCNTs共混物中,MWCNTs呈现随机排列的结构; 而在由共挤出制备的复合纤维中,MWCNTs可以沿纤维的轴向发生明显取向。与普通共混物相比,PE/MWCNTs复合纤维的力学强度得到了明显的改善。
Abstract:
Polyethylene/multi-walled carbon nanotubes(PE/MWCNTs)nanofibers with high mechan-ical strength were successfully prepared by coextrusion process. In order to solve the dispersion of MWCNTs in PE matrix, simple paraffin wax coating process was conducted. The effects of the introduction of MWCNTs on the properties of PE nanofibers were investigated by infrared spectroscopy, optical microscopy, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy and electronic universal testing machine. The results showed that the prepared composite nanofibers have a continuous and uniform structure. MWCNTs are randomly aligned in common PE/MWCNTs blends. However, in the one-dimensional confined space created by nanolayer coextrusion, paraffin wax-coated MWCNTs can be well aligned along the axial direction of nanofibers. Compared with common blends, the mechanical properties of PE/MWCNTs nanofibers have been greatly improved.
