采用静电纺丝法制备了直径从40 nm到几百nm的聚对苯二甲酰对苯二胺（PPTA）超细纤维。该纤维具有圆形横截面，是双折射的，并且在高于400摄氏度的温度下稳定。电子衍射图案从这两个纺和退火纤维显示赤道和赤道反射，证明在材料中的顺序。采用明场和暗场电子显微镜、电子衍射和原子力显微镜对纤维的晶体结构和形貌进行了表征。
Very small diameter fibers of poly(p-phenylene terephthalamide) (PPTA) ranging in diameter from 40 nm to a few hundreds of nanometers were made by the electrospinning process. The fibers have a circular cross-section, are birefringent and stable at temperatures greater than 400 degrees C. Electron diffraction patterns obtained from both as-spun and annealed fibers show meridional and equatorial reflections demonstrating order in the material. The crystal structure and morphology of the fibers were characterized using bright and dark field electron microscopy, electron diffraction and atomic force microscopy.
