| 摘 要： | 用静电纺丝的方法制得聚丙烯腈纳米纤维,并在250℃预氧化,850℃炭化,得到碳纳米纤维。对静电纺纳米纤维、预氧化后纳米纤维和炭化后纳米纤维的表面形态结构用扫描电镜进行分析,并比较其强伸、导电性能,发现碳纳米纤维的导电性能大大增强。原料聚丙烯腈粉末、静电纺纳米纤维、预氧化后纳米纤维和炭化后纳米纤维的内部结构变化采用X射线衍射和红外光谱法进行分析。

| Abstract: | Polyacrylonitrile(PAN) nanofibers were manufactured by electrospinning,and then preoxidized at(250 ℃) and carbonized at 850 ℃,thus obtained carbon nanofibers.The morphology of electrospun nanofibers,preoxidized nanofibers and carbon nanofibers was studied by scanning electron microscope(SEM),and their tensile and elongation,and conductivity were compared.It was found that the conductivity of the carbon nanofibers enhanced significantly.Characterization of the microstructure of PAN powder,electrospun nanofibers,preoxidized nanofibers and carbon nanofibers was performed by X-ray diffractometry and infrared spectroscopy. |
