采用熔融纺丝法制备的PP（聚丙烯）/有机粘土纳米复合材料纤维，通过SEM、FTIR、XRD、DSC和力学性能测试等手段对其进行了表征。结果表明，在PP基体中添加0.1%的有机粘土，提高了PP/有机粘土纳米复合纤维的结晶度和力学性能（抗拉强度）。随着有机粘土含量的增加（≥0.3%），纤维的结晶度和抗拉强度均略有下降，且在相同拉伸比下，含有机粘土纤维在加热过程中呈现出多峰现象。此外，在红外二色性测试中，聚丙烯中有机粘土的添加量较低（0.1%），纤维的取向度略有提高。©2010 Wiley期刊公司高分子学报，2010
Fibers prepared by melt spinning process from the PP (polypropylene)/organoclay nanocomposite were characterized in details with the aid of SEM, FTIR, XRD, DSC, and mechanical measurements. The results suggested that the lower content of organoclay (0.1%) added to the PP matrix increased the crystallinity and mechanical property (tensile strength) of the PP/organoclay nanocomposite fiber. With increasing the content of organoclay (≥ 0.3%), the crystallinity and the tensile strength both a little decreased, and the fiber containing organoclay exhibited multi-peaks at the same draw ratio during the heating process. Furthermore, the degree of orientation of the fiber increased a little with lower content of organoclay (0.1%) introduction to PP during the infrared dichroism measurement. © 2010 Wiley Periodicals, Inc.
