对多壁碳纳米管(MWCNT)进行表面有机化改性处理后，采用向纺丝溶剂中滴加纳米粒子悬浮液的混合方式，制备了超高分子量聚乙烯(PE-UHMW)／MWCNT复合纤维。通过紫外分光光度计、扫描电子显微镜、热台偏光显微镜分析了MWCNT在基体中的分散情况，并利用X射线衍射、力学性能测试、差示扫描量热分析、热重分析等测试方法对复合纤维的结构及性能进行了表征分析。结果表明，MWCNT分散良好的复合纤维，其力学性能得到了提升，耐热性和耐蠕变性也得到了不同程度的改善。

Multi-walled carbon nano-tubes(MWCNT)/ultra-high molecular weight polyethylene(PE-UHMW) composite fiber was prepared through adding suspension of MWCNT modified with organic reagent drop by drop. The dispersion of MWCNT in polymer matrix was observed and analyzed by ultraviolet spectrophotometer,scanning electron microscopy,thermal platform microscope,and the properties of the composite fiber were characterized using x-ray diffraction,differential scanning caldrimetry, mechanics performance testing,thermogravimetric analysis.The experiment results show that the MWCNT/PE-UHMW fiber is improved in the performances such as mechanical properties,thermal stability and creep resistance.
