摘　　要：利用红外光谱分析、热重分析、差示扫描量热分析、X射线衍射分析等方法,对聚乙烯纤维、聚丙烯纤维、聚四氟乙烯纤维分别进行表征,得到不同纤维的特征谱图和数据。多种方法结合可实现对聚乙烯纤维、聚丙烯纤维、聚四氟乙烯纤维的鉴别。Polyethylene(PE)fibers,polypropylene(PP)fibers and polytetrafluoroethylene(PTFE)fibers were characterized by infrared spectroscopic analysis,thermogravimetric analysis,differential scanning calorimetric analysis and X-ray diffraction analysis,and the characteristic spectra and data of different fibers were obtained.The combination of multiple methods could realize the identification of PE fibers,PP fibers and PTFE fibers.
