Abstract

The crystalline morphology of electrospun PCL nanofibers was studied. Random and aligned nanofibers were obtained by a conventional plate collector and a two-parallel-conductive-plate collector, respectively. Scanning electron microscopy and 2D wide-angle X-ray diffraction were employed to characterize the nanofibers. The degree of crystallinity of aligned nanofibers was higher than that of randomly aligned nanofibers. The crystallites in the nanofibers were highly oriented along the nanofiber axis, as were the molecular chains. The estimated crystallite size in the nanofibers suggested that a single nanofiber was composed of dozens of nanofibrils and a nanofibril was further composed of crystallites along the nanofiber axis with an amorphous region of extended PCL molecular chains between neighboring crystallites.
